Hydrogen production. Green algae as a source of energy. (1/164)

Hydrogen gas is thought to be the ideal fuel for a world in which air pollution has been alleviated, global warming has been arrested, and the environment has been protected in an economically sustainable manner. Hydrogen and electricity could team to provide attractive options in transportation and power generation. Interconversion between these two forms of energy suggests on-site utilization of hydrogen to generate electricity, with the electrical power grid serving in energy transportation, distribution utilization, and hydrogen regeneration as needed. A challenging problem in establishing H(2) as a source of energy for the future is the renewable and environmentally friendly generation of large quantities of H(2) gas. Thus, processes that are presently conceptual in nature, or at a developmental stage in the laboratory, need to be encouraged, tested for feasibility, and otherwise applied toward commercialization.  (+info)

The health impacts of exposure to indoor air pollution from solid fuels in developing countries: knowledge, gaps, and data needs. (2/164)

Globally, almost 3 billion people rely on biomass (wood, charcoal, crop residues, and dung) and coal as their primary source of domestic energy. Exposure to indoor air pollution (IAP) from the combustion of solid fuels is an important cause of morbidity and mortality in developing countries. In this paper, we review the current knowledge on the relationship between IAP exposure and disease and on interventions for reducing exposure and disease. We take an environmental health perspective and consider the details of both exposure and health effects that are needed for successful intervention strategies. We also identify knowledge gaps and detailed research questions that are essential in successful design and dissemination of preventive measures and policies. In addition to specific research recommendations, we conclude that given the interaction of housing, household energy, and day-to-day household activities in determining exposure to indoor smoke, research and development of effective interventions can benefit tremendously from integration of methods and analysis tools from a range of disciplines in the physical, social, and health sciences.  (+info)

Daily average exposures to respirable particulate matter from combustion of biomass fuels in rural households of southern India. (3/164)

Indoor air pollution resulting from combustion of biomass fuels in rural households of developing countries is now recognized as a major contributor to the global burden of disease. Accurate estimation of health risks has been hampered by a paucity of quantitative exposure information. In this study we quantified exposures to respirable particulate matter from biomass-fuel combustion in 436 rural homes selected through stratified random sampling from four districts of Tamil Nadu, India. The study households are a subset of a larger sample of 5,028 households from the same districts in which socioeconomic and health information has been collected. Results of measurements for personal exposures to respirable particulate matter during cooking were reported earlier. This has been extended to calculation of 24-hr exposures with the aid of additional measurements during noncooking times and the collection of time-activity records. Concentrations of respirable particulate matter ranged from 500 to 2,000 micro g/m(3) during cooking in biomass-using households, and average 24-hr exposures ranged from 90 +/- 21 micro g/m(3) for those not involved in cooking to 231 +/- 109 micro g/m(3) for those who cooked. The 24-hr exposures were around 82 +/- 39 micro g/m(3) for those in households using clean fuels (with similar exposures across household subgroups). Fuel type, type and location of the kitchen, and the time spent near the kitchen while cooking were the most important determinants of exposure across these households among other parameters examined, including stove type, cooking duration, and smoke from neighborhood cooking. These estimates could be used to build a regional exposure database and facilitate health risk assessments.  (+info)

The origin, fate, and health effects of combustion by-products: a research framework. (4/164)

Incomplete combustion processes can emit organic pollutants, metals, and fine particles. Combustion by-products represent global human and environmental health challenges that are relevant not only in heavily industrialized nations, but also in developing nations where up to 90% of rural households rely on unprocessed biomass fuels for cooking, warmth, and light. These issues were addressed at the Seventh International Congress on Combustion By-Products, which convened 4-6 June 2001 in Research Triangle Park, North Carolina. This congress included a diverse group of multidisciplinary researchers and practitioners who discussed recent developments and future goals in the control of combustion by-products and their effects of exposure on human and ecologic health. Participants recommended that interdisciplinary, coordinated research efforts should be focused to capitalize on the important potential synergisms between efforts to reduce the adverse human health effects linked to exposures to combustion by-products and broader efforts to reduce greenhouse gas emissions and save energy through efficiency. In this article we summarize the principal findings and recommendations for research focus and direction.  (+info)

Electricity generation by direct oxidation of glucose in mediatorless microbial fuel cells. (5/164)

Abundant energy, stored primarily in the form of carbohydrates, can be found in waste biomass from agricultural, municipal and industrial sources as well as in dedicated energy crops, such as corn and other grains. Potential strategies for deriving useful forms of energy from carbohydrates include production of ethanol and conversion to hydrogen, but these approaches face technical and economic hurdles. An alternative strategy is direct conversion of sugars to electrical power. Existing transition metal-catalyzed fuel cells cannot be used to generate electric power from carbohydrates. Alternatively, biofuel cells in which whole cells or isolated redox enzymes catalyze the oxidation of the sugar have been developed, but their applicability has been limited by several factors, including (i) the need to add electron-shuttling compounds that mediate electron transfer from the cell to the anode, (ii) incomplete oxidation of the sugars and (iii) lack of long-term stability of the fuel cells. Here we report on a novel microorganism, Rhodoferax ferrireducens, that can oxidize glucose to CO(2) and quantitatively transfer electrons to graphite electrodes without the need for an electron-shuttling mediator. Growth is supported by energy derived from the electron transfer process itself and results in stable, long-term power production.  (+info)

Exposure assessment for respirable particulates associated with household fuel use in rural districts of Andhra Pradesh, India. (6/164)

Indoor air pollution associated with combustion of solid fuels seems to be a major contributor to the national burden of disease in India, but relatively few quantitative exposure assessment studies are available. This study quantified the daily average concentrations of respirable particulates (50% cut-off at 4 microm) in 412 rural homes selected through stratified random sampling from three districts of Andhra Pradesh, India and recorded time activity data from 1400 individuals to reconstruct 24-h average exposures. The mean 24-h average concentrations ranged from 73 to 732 microg/m(3) in gas- versus solid fuel-using households, respectively. Concentrations were significantly correlated with fuel type, kitchen type, and fuel quantity. The mean 24-h average exposures ranged from 80 to 573 microg/m(3). Among solid fuel users, the mean 24-h average exposures were the highest for women cooks and were significantly different from men and children. Among women, exposures were the highest in the age group of 15-40 years (most likely to be involved in cooking or helping in cooking), while among men, exposures were highest in the age group of 65-80 years (most likely to be indoors). The data are being used to develop a model to predict quantitative categories of population exposure based on survey information on housing and fuel characteristics. This would facilitate the development of a regional exposure database and enable better estimation of health risks.  (+info)

Potential role of a novel psychrotolerant member of the family Geobacteraceae, Geopsychrobacter electrodiphilus gen. nov., sp. nov., in electricity production by a marine sediment fuel cell. (7/164)

Previous studies have shown that members of the family Geobacteraceae that attach to the anodes of sediment fuel cells are directly involved in harvesting electricity by oxidizing organic compounds to carbon dioxide and transferring the electrons to the anode. In order to learn more about this process, microorganisms from the anode surface of a marine sediment fuel cell were enriched and isolated with Fe(III) oxide. Two unique marine isolates were recovered, strains A1(T) and A2. They are gram-negative, nonmotile rods, with abundant c-type cytochromes. Phylogenetic analysis of the 16S rRNA, recA, gyrB, fusA, rpoB, and nifD genes indicated that strains A1(T) and A2 represent a unique phylogenetic cluster within the Geobacteraceae. Both strains were able to grow with an electrode serving as the sole electron acceptor and transferred ca. 90% of the electrons available in their organic electron donors to the electrodes. These organisms are the first psychrotolerant members of the Geobacteraceae reported thus far and can grow at temperatures between 4 and 30 degrees C, with an optimum temperature of 22 degrees C. Strains A1(T) and A2 can utilize a wide range of traditional electron acceptors, including all forms of soluble and insoluble Fe(III) tested, anthraquinone 2,6-disulfonate, and S(0). In addition to acetate, both strains can utilize a number of other organic acids, amino acids, long-chain fatty acids, and aromatic compounds to support growth with Fe(III) nitrilotriacetic acid as an electron acceptor. The metabolism of these organisms differs in that only strain A1(T) can use acetoin, ethanol, and hydrogen as electron donors, whereas only strain A2 can use lactate, propionate, and butyrate. The name Geopsychrobacter electrodiphilus gen. nov., sp. nov., is proposed for strains A1(T) and A2, with strain A1(T) (ATCC BAA-880(T); DSM 16401(T); JCM 12469) as the type strain. Strains A1(T) and A2 (ATCC BAA-770; JCM 12470) represent the first organisms recovered from anodes that can effectively couple the oxidation of organic compounds to an electrode. Thus, they may serve as important model organisms for further elucidation of the mechanisms of microbe-electrode electron transfer in sediment fuel cells.  (+info)

Evidence for involvement of an electron shuttle in electricity generation by Geothrix fermentans. (8/164)

In experiments performed using graphite electrodes poised by a potentiostat (+200 mV versus Ag/AgCl) or in a microbial fuel cell (with oxygen as the electron acceptor), the Fe(III)-reducing organism Geothrix fermentans conserved energy to support growth by coupling the complete oxidation of acetate to reduction of a graphite electrode. Other organic compounds, such as lactate, malate, propionate, and succinate as well as components of peptone and yeast extract, were utilized for electricity production. However, electrical characteristics and the results of shuttling assays indicated that unlike previously described electrode-reducing microorganisms, G. fermentans produced a compound that promoted electrode reduction. This is the first report of complete oxidation of organic compounds linked to electrode reduction by an isolate outside of the Proteobacteria.  (+info)

TY - JOUR. T1 - Analysis of chitin particle size on maximum power generation, power longevity, and Coulombic efficiency in solid-substrate microbial fuel cells. AU - Rezaei, Farzaneh. AU - Richard, Tom L.. AU - Logan, Bruce E.. PY - 2009/7/15. Y1 - 2009/7/15. N2 - Microbial fuel cells (MFCs) produce bioelectricity from a wide variety of organic and inorganic substrates. Chitin can be used as a slowly degrading substrate in MFCs and thus as a long-term fuel to sustain power by these devices in remote locations. However, little is known about the effects of particle size on power density and length of the power cycle (longevity). We therefore examined power generation from chitin particles sieved to produce three average particle sizes (0.28, 0.46 and 0.78 mm). The longevity increased from 9 to 33 days with an increase in the particle diameter from 0.28 to 0.78 mm. Coulombic efficiency also increased with particle size from 18% to 56%. The maximum power density was lower for the largest (0.78 mm) ...

Microbial fuel cells are batteries in which microorganisms catalyze the conversion of organic fuel (such as lactate) into protons and electrons that power a resistor (e. g., a light bulb) before reducing the terminal electron acceptor (e. g., oxygen is reduced to water). Great improvements in power production and efficiency have been made by engineering inorganic components, such as the electrodes themselves, to be more efficiently utilized by fuel cell-inhabiting organisms. However, other avenues for improvement may exist, that is, engineering the fuel cell-inhabiting organisms themselves. We hypothesized that Shewanella oneidensis MR-1, a model organism used for studying microbial fuel cells, could be shown to evolve under physiological conditions which mimic those found in microbial fuel cells. These physiological conditions include the planktonic lifestyle, the biofilm lifestyle, and transient association between the two - that is, those cells that rapidly detach from and reattach to the ...

Figure 5.6 shows that the introduction of renewable technologies under the Energy [R]evolution scenario increase the future costs of electricity generation compared to the Reference scenario until 2020. This difference will be less than 0.8 US$ct/kWh up to 2020, however. Because of high prices for conventional fuels and the lower CO2 intensity of electricity generation, from 2030 on electricity generation costs will become economically favourable under the Energy [R]evolution scenario and by 2050 costs will be 7.5 US$ct/kWh below those in the Reference version. Under the Reference scenario, on the other hand, unchecked growth in demand, an increase in fossil fuel prices and the cost of CO2 emissions result in total electricity supply costs rising from todays US$ 96 billion per year to more than US$ 555 billion in 2050, compared to US$ 327 billion in the Energy [R]evolution scenario.

In this paper the community composition of denitrifiers in the cathode of a MFC is analysed in relation to added electron acceptors (nitrate and nitrite) and organic matter in the cathode. Nitrate reducers and nitrite reducers were highly affected by the operational conditions and displayed high diversity. The number of retrieved species-level Operational Taxonomic Units (OTUs) for narG, napA, nirS and nirK genes was 11, 10, 31 and 22, respectively. In contrast, nitrous oxide reducers remained virtually unchanged at all conditions. About 90% of the retrieved nosZ sequences grouped in a single OTU with a high similarity with Oligotropha carboxidovorans nosZ gene. nirS-containing denitrifiers were dominant at all conditions and accounted for a significant amount of the total bacterial density. Current production ...

TY - JOUR. T1 - A small-scale air-cathode microbial fuel cell for on-line monitoring of water quality. AU - Di Lorenzo, M. AU - Thomson, Alexander R.. AU - Schneider, Kenneth. AU - Cameron, Petra J. AU - Ieropoulosc, Ioannis. PY - 2014/12/15. Y1 - 2014/12/15. N2 - The heavy use of chemicals for agricultural, industrial and domestic purposes has increased the risk of freshwater contamination worldwide. Consequently, the demand for efficient new analytical tools for on-line and on-site water quality monitoring has become particularly urgent.In this study, a small-scale single chamber air-cathode microbial fuel cell (SCMFC), fabricated by rapid prototyping layer-by-layer 3D printing, was tested as a biosensor for continuous water quality monitoring.When acetate was fed as the rate-limiting substrate, the SCMFC acted as a sensor for chemical oxygen demand (COD) in water. The linear detection range was 3-164 ppm, with a sensitivity of 0.05 μA mM−1cm−2 with respect to the anode total surface ...

The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors which support Fe(III) oxide reduction by this organism. Current was produced using a coculture of P. carbinolicus and Geobacter sulfurreducens with ethanol as the fuel. Ethanol consumption was associated with the transitory accumulation of acetate and hydrogen. G. sulfurreducens alone could not metabolize ethanol, suggesting that P. carbinolicus grew in the fuel cell by converting ethanol to hydrogen and acetate, which G. sulfurreducens oxidized with electron transfer to the anode. Up to 83% of the electrons available in ethanol were recovered as electricity and in the metabolic intermediate acetate. ...

Conducting shell for bacteria - Scienmag: Latest Science and Health News  Conducting shell for bacteria - Scienmag: Latest Science and Health News
Under anaerobic conditions, certain bacteria can produce electricity. This behavior can be exploited in microbial fuel cells, with a special focus on wastewater treatment schemes. A weak point is the dissatisfactory power density of the microbial cells. An unconventional solution is now presented by Singaporean and Chinese scientists: as reported in the journal Angewandte Chemie, they coated live, electroactive bacteria with a conducting polymer and obtained a high-performance anode for microbial fuel cells.. The history of microbial fuel cells goes back to the beginning of the 20th century when scientists connected bacteria cells with electrodes to generate electricity. The principle is that, if no oxygen is present, the bacterias metabolism changes to produce protons and electrons instead of carbon dioxide and water. These electrons can be used for current generation in an electrochemical cell. Such microbial fuel cells are currently heavily investigated for sustainable energy production and, ...

Microbial catalysis of the oxygen reduction reaction for microbial fuel cells: a review. - oatao  Microbial catalysis of the oxygen reduction reaction for microbial fuel cells: a review. - oatao
The slow kinetics of the electrochemical oxygen reduction reaction (ORR) is a crucial bottleneck in the development of microbial fuel cells (MFCs). This article firstly gives an overview of the particular constraints imposed on ORR by MFC operating conditions: neutral pH, slow oxygen mass transfer, sensitivity to reactive oxygen species, fouling and biofouling. A review of the literature is then proposed to assess how microbial catalysis could afford suitable solutions. Actually, microbial catalysis of ORR occurs spontaneously on the surface of metallic materials and is an effective motor of microbial corrosion. In this framework, several mechanisms have been proposed, which are reviewed in the second part of the article. The last part describes the efforts made in the domain of MFCs to determine the microbial ecology of electroactive biofilms and define efficient protocols for the formation of microbial oxygen-reducing cathodes. Although no clear mechanism has been established yet, several ...

A marine microbial fuel cell (MFC) type biosensor was developed for the detection of assimilable organic carbon (AOC) in ocean water for the purpose of online water quality monitoring for seawater desalination plants prone to biofouling of reverse osmosis (RO) membranes. The anodophilic biofilm that developed on the graphite tissue anode could detect acetate as the model AOC to concentrations as low as 5 µM (120 µg/L of AOC), which is sufficiently sensitive as an online biofouling risk sensor. Although the sensor was operated at a higher (+200 ± 10 mV) than the usual (-300 mV) anodic potential, the presence of oxygen completely suppressed the electrical signal. In order to overcome this outcompeting effect of oxygen over the anode as electron acceptor by the bacteria, hexacyanoferrate (HCF(III)) was found to enable the development of an adapted biofilm that transferred electrons to HCF(III) rather than oxygen. As the resultant of the reduced HCF(II) could readily transfer electrons to the ...

British Library EThOS: Development of an aerobic biocathode for microbial fuel  British Library EThOS: Development of an aerobic biocathode for microbial fuel
Microbial fuel cells (MFCs), which convert organic waste to electricity using microbes, could be used to make the wastewater infrastructure more energy efficient and sustainable. However, the chemical catalysts which catalyse the oxygen reduction reaction (ORR) at the cathode of MFCs are expensive and unsustainable. Mixed community aerobic biocathode biofilms are an alternative to chemical catalysts. However, little is known about the bacteria, their metabolism, and their mechanisms of electron transfer with the electrode. A novel 4-electrode method was used to determine the minimum potential for production of peroxide on a porous carbon felt biocathode support. Biocathodes with a high onset potential for the ORR of +0.4 V vs Ag/AgCl were then cultivated in poised-potential half-cells at working electrode potentials of -0.1 and +0.2 V vs Ag/AgCl. These biofilms show what may be an electrode potential-dependent switch in an electron transfer mechanism from -0.1 to +0.2 V vs Ag/AgCl. The biofilms ...

0019] As shown in the lower portion of FIG. 2, conventional ball milling of K2FeO4 heats the particles and converts some to the ferric state. Chemically synthesized, re-crystallized K2FeO4 was milled in a Restch PM 100 planetary ball in a steel vessel with steel grinding balls at approximately 500 revolutions per minute (rpm) ball milling for approximately 45 minutes. The resulting nanometer-size particles and 10 weight percent carbon (based on the total amount of K2FeO4 and carbon) were used to form a cathode. The cathode had a decreased coulombic efficiency (approximately 37%) compared to the coulombic efficiency of a comparable cathode made using non-milled K2FeO4 (53% coulombic efficiency). However the discharge voltage increased and the coulombic efficiency increased to approximately 47% when the milling time was shortened to approximately 15 minutes.

Q: If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?  Q: If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?
Physicist: Electrical energy is nothing special. Just like the chemical energy in our bodies, it breaks down into heat. For example, the heat given off by light bulbs (or electric heaters for that matter!) is a result of electrical energy. When electricity is flowing to a light bulb, thats where the electrical energy is going; its turning into light. When you pull the plug (so to speak) what tiny, tiny amount of electrical energy there is in the wires runs out almost immediately.. The term "electrical energy" is actually a little vague. So, to be specific, in our nervous system there are tiny ion pumps that maintain an imbalance of charges between the inside and outside of the nerve cells. When a nerve cell fires, charges are allowed to suddenly flow through the cell membrane in a process called an "action potential". The way electricity flows along nerve cells is different from the way it flows down a telegraph wire ("inside-to-outside" instead of "along"), but whatever. The point is, there ...

Oxygen suppresses light-driven anodic current generation by a mixed phototrophic culture - UQ eSpace  Oxygen suppresses light-driven anodic current generation by a mixed phototrophic culture - UQ eSpace
This paper describes the detrimental effect of photosynthetically evolved oxygen on anodic current generation in the presence of riboflavin upon illumination of a mixed phototrophic culture enriched from a freshwater pond at +0.6 V vs standard hydrogen electrode. In the presence of riboflavin, the phototrophic biomass in the anodic compartment produced an electrical current in response to light/dark cycles (12 h/12 h) over 12 months of operation, generating a maximum current density of 17.5 mA.m(-2) during the dark phase, whereas a much lower current of approximately 2 mA.m(-2) was generated during illumination. We found that the low current generation under light exposure was caused by high rates of reoxidation of reduced riboflavin by oxygen produced during photosynthesis. Quantification of biomass by fluorescence in situ hybridization images suggested that green algae were predominant in both the anode-based biofilm (55.1%) and the anolyte suspension (87.9%) with the remaining biovolume ...

Fuel Cell Flexibility and Sustainability | WBDG Whole Building Design Guide  Fuel Cell Flexibility and Sustainability | WBDG Whole Building Design Guide
As populations continue to grow, the amount of waste produced also increases; 61 percent of energy is wasted by the U.S. economy each year, and most of it can be attributed to our relatively inefficient power plants.1 Fuel cells are capable of reducing waste to increase efficiency and produce marketable energy. Processed municipal waste produces anaerobic digested gas, commonly known as biogas, which can be used as a fuel for fuel cells cell fuel. While hydrogen is the most common fuel type for fuel cells, biogas such as methane, natural gas, propane and diesel can be used as well. Biogas is an ideal option for fuel cells because it is easily stored and produces almost zero net carbon dioxide emissions. When biogas is fed into fuel cells, heat, electricity, and water are produced,2 providing on-site power for the facility. Some fuel cells are efficient enough to create excess hydrogen that can be sold to fuel cell stations and be utilized by fuel cell electric vehicles (FCEV).. The Orange County ...

The depletion of fossil fuel reserves, global warming, energy security and the need for clean, cheap fuels has made developing sources of renewable energy a global research priority. Microbial Fuel Cells (MFCs) have the potential to generate renewable electricity from a vast array of carbon sources such as waste-water, agricultural by-products and industrial pollutants. In MFCs electrons from microbial metabolism flow from the bacteria toward an anode then on through an external circuit finally converting oxygen into water at the cathode closing the cycle. The optimization of MFC systems is a highly multidisciplinary area of research and two complementary areas of work are required - firstly to design more efficient hardware for the cells by traditional engineering and secondly to understand and improve the interaction and electron transport between microbes and electrode via biological engineering.

In experiments, biofuel cells have harnessed membranes of living bacteria to separate anode from cathode--enabling them to share an electrolyte chamber like a lead-acid battery. Now, researchers at the Pacific Northwest National Laboratory have purified the essential protein performing a fuel-cell membranes electronic function, clearing the way to commercialize biofuel cells sans bacteria. The team purified the bacterium down to the essential protein in the cell wall--eliminating the need to keep the bacterium alive. The only missing element was a fuel source, which biomass could supply, lab scientists reasoned. Now they propose biofuel cell arrays to harvest biomass in tiny reactors. The reaction creates a mobile electron carrier that shuttles electrons to the protein-coated electrodes, generating electricity as it neutralizes the biomass. The proposed biofuel cells would use a cheap porous hematite electrode in which the bacterias purified protein could be bound. The coated electrodes would ...

One of the remaining challenges driving polymer electrolyte membrane hydrogen fuel cell research is the durability of the Pt oxygen reduction reaction (ORR) catalyst. Pt is inherently unstable; minute amounts (in the order of ng/cm2 are dissolved every time the fuel cell is started, goes from idle to load, or shut-down. In addition, corrosion of carbon-based materials (ubiquitous inside fuel cells) occurs during the start-up and shut-down and also contributes to the steady decline of fuel cell performance. Adding oxygen evolution reaction (OER) catalysts, of which only Ru and Ir are stable in the acidic conditions of the fuel cell, can decrease Pt loss and carbon corrosion by mitigating the degradation mechanism which occurs during the start-up and shut-down phases. There are two challenges in developing this materials solution (there are other solutions, based on hardware systems) to the fuel cell durability problem: 1) finding the right mixture of Ru and Ir, (Ru is cheaper, more active, but ...

Ancient cultures understood that the body possessed a special energy that was responsible for life. The Chinese called this life force energy, Qi. I believe that what they were talking about is bioelectricity.. Bioelectricity. Electricity is a force that results from the interaction between positive and negative charges. Like charges repel while opposites attract. In the body there are different atoms and molecules that have positive or negative charges associated with them. We call these charged particles ions. Bioelectricity (the kind of electricity used in the body) is generated by the movement of these ions.. It is the controlled flow of ions that allows signals to be carried by the nerves of our brains and nervous systems. That means that every thought we have is a result of bioelectricity. This same basic process is responsible for the contraction of our muscles. So, every movement we make and every beat of our hearts are powered by electricity.

In a fuel cell system including a stack of polymer electrolyte fuel cells, the wet state of electrolyte membranes in the fuel cell stack is detected according to a variation in measurement value of an alternating current impedance (AC impedance) of the fuel cell stack. In an adequate level of water content of the electrolyte membranes, the measurement value of the AC impedance is substantially constant and has a very little variation. In an excess level of water content of the electrolyte membranes, the measurement value of the AC impedance has a significant variation. The AC impedance of the fuel cell stack is determinable by frequency analysis of high-frequency noise generated by an inverter included in the fuel cell system.

Metal hydride fuel cell - Wikipedia  Metal hydride fuel cell - Wikipedia
Metal hydride fuel cells are a subclass of alkaline fuel cells that are in the research and development phase. A notable feature is their ability to chemically bond and store hydrogen within the cell. This feature is shared with direct borohydride fuel cells, although the two differ in that MHFCs are refueled with pure hydrogen. Though the absorption characteristic of metal hydrides (around 2%) is far lower than sodium-borohydrides and other "light" metal hydrides (around 10.8%), prototypes have been claimed to demonstrate a number of interesting characteristics: The ability to be recharged with electrical energy (similar to NiMH batteries); Low operating temperatures (down to −20°C); Fast kinetics; Extended shelf life; Fast "cold start" properties; Ability to operate for limited periods of time with no external hydrogen source, enabling "hot swapping" of fuel canisters. Metal hydrides fuel cells are being researched by ECD Ovonics, as well as by the Japanese National Institute of Advanced ...

Nanotechnology Now - News Story: From waste to power in one step  Nanotechnology Now - News Story: From waste to power in one step
A revolutionary new environmental biotechnology - the Microbial Fuel Cell - turns the treatment of organic wastes into a source of electricity. Fuel cell technology, despite its recent popularity as a possible solution for a fossil-fuel free future, is actually quite old. The principle of the fuel cell was discovered by German scientist Christian Friedrich Sch nbein in 1838 and published in 1839. Based on this work, the first fuel cell was developed by Welsh scientist Sir William Robert Grove in 1843. The operating principle of a fuel cell is fairly straightforward. It is an electrochemical energy conversion device that converts the chemical energy from fuel (on the anode side) and oxidant (on the cathode side) directly into electricity. Today, there are many competing types of fuel cells, depending on what kind of fuel and oxidant they use. Many combinations of fuel and oxidant are possible. For instance, hydrogen cell uses hydrogen as fuel and oxygen as oxidant. Other fuels include ...

In practice, the electrode response is expected to be nonlinear. A possible additional contributor to nonlinearity is oxidation of the electrolyte, particularly at the air electrode, where polarization losses are expected to be greatest. Such oxidation would enhance the electronic leakage which occurs as a result of p-type conductivity.49 Nevertheless, these expressions provide a valuable estimate of the impact of the various electrical terms on the faradaic efficiency and provide a reference for comparison to the measured faradaic efficiencies.. A trace of the hydrogen detected under different voltage conditions, Fig. 4d and Fig. S6 (ESI†), reveals that the protonic current is substantially lower than the total current, Fig. 4a, and accordingly the faradaic efficiency, Fig. 4e, is measurably lower than 100%, ranging from 40 to 75% over the measurement conditions examined here. Moreover, this efficiency is independent of the gas flow rate, as expected for losses due to electronic conductivity ...

Bernie Schopper - Vitamin C - Variation 2b  Bernie Schopper - Vitamin C - Variation 2b
An abstract from the authors statement Suppose one were to devise some sort of "lens" that could focus electrical energy into a single point, much like a magnifying glass focusing sunlight on a combustible object. In the second case, the heat generated would be so intense, it could set the object on fire. What would happen in the first case? That is what I wanted to find out, since focusing electrical energy into a very small area sets up a field of such an intense energy, that the structure of matter might be altered. After two years of research and experimentation (I am an amateur scientist and entrepreneur), I have designed such a device, capable of concentrically focusing electrical energy. Then, I discovered when certain crystals are exposed to this intense electric field during their growth process, some samples form microscopic landscapes of extraordinary beauty (at least in the eye of this beholder :)). Each crystal landscape created in this manner is unique, but highly unstable and ...

Biofuel Cells - Implantable BioFuel Cells (IBFC)  Biofuel Cells - Implantable BioFuel Cells (IBFC)
Various biofuels pathways have been under research in the last decades, but most of them have showed limited applications because of their insufficient energy output (inferior to the minimal threshold of 5 mW/mL needed to supply biomedical devices). For instance, systems that utilize vibrations or body movements to scavenge power for an implanted device are currently limited to few μW/mL in the best cases due to low frequency of body movements or heart contractions. Seebeck thermoelectric effect cannot be used for implanted devices because there is almost no differential temperature inside the body. Betavoltaic cells could be used for isotope energy conversion but current density is still low like NanoTritium™ from Citylabs which current is 0.1 μA/cm2 for 0.7V.. In recent years, two types of Biofuel Cells have been making headlines for their energy output potential:. - Glucose BioFuel Cells (GBFC), which exploiting the ubiquitous presence of glucose in body fluids for energy ...

The giant fuel cell system is based on Ballards proton-exchange membrane technology that has been successfully proven in a number of smaller commercial power applications ranging from 1 kilowatt (kW) up to 150 kW, including powering 40-foot mass transit buses. Because fuel cells use hydrogen to generate electricity and produce only heat and water as byproducts, they are a more environmentally friendly means of generating power than diesel or coal. Because its on wheels, the unit can be moved to provide emergency power during outages for up to 500 homes or used to supplement power during peak load periods, such as during summer months when air conditioning demand is high. "We are discovering that there is great opportunity for megawatt-scale clean-energy solutions using fuel cells. And, smaller-scale fuel cell systems can provide backup for telecom companies, for instance, if the grid goes down.

FUEL CELLS USING ORGANIC REDOX COMPOUNDS,  FUEL CELLS USING ORGANIC REDOX COMPOUNDS,
In living systems, hydrogen supplied from the TCA cycle is transferred to molecular oxygen and oxidized by the electron carrier system, thereby generating energy. It appears that the reversible redox system such as the electron carrier system has not yet been studied in vitro. It was considered that the system of cystine-cysteine containing ferric ion or that of quinone-hydroquinone containing an enzyme might act like the electron carrier system. The authors attempted to use the electron carrier system at the cathode of a fuel cell to obtain a greater amount of electric current. As a result, it has been demonstrated that a fuel cell, based on the model of carrier systems, shows the properties of larger current density and capacity than the ordinary fuel cell and following the model of the carrier system, oxidation and reduction can be repeated alternately without consumption of reactants.

Proton-exchange membrane fuel cells (PEMFCs) are expected to provide a complementary power supply to fossil fuels in the near future. The current reliance of fuel cells on platinum catalysts is undesirable. However, even the best-performing non-noble metal catalysts are not as efficient. To drive commercial viability of fuel cells forward in the short term, increased utilization of Pt catalysts is paramount. We have demonstrated improved power and energy densities in a single PEMFC using a designed cathode with a Pt loading of 0.1 mg cm−2 on a mesoporous conductive entangled carbon nanotube (CNT)-based architecture. This electrode allows for rapid transfer of both fuel and waste to and from the electrode, respectively. Pt particles are bound tightly, directly to CNT sidewalls by a microwave-reduction technique, which provided increased charge transport at this interface. The Pt entangled CNT cathode, in combination with an E-TEK 0.2 mg cm−2 anode, has a maximum power and energy density of ...

The object of the invention is the coupling of a hydrogen fuel cell to an enzymatic process for the production of electricity and the transformation and sequestration of CO2. Gaseous CO2 emissions from processes such as hydrocarbon reforming are transformed into carbonate or bicarbonate ions and hydrogen ions by the enzymatic system in order to prevent their contribution to the greenhouse effect. The hydrogen ions resulting from the enzymatic process are recovered and combined in order to supply the hydrogen fuel cell. Finally, water, a by-product of the oxidizing reaction of the hydrogen fuel cell, is recovered and recycled back into the aqueous enzymatic system.

The Effect of Voltage Cycling on Catalyst Degradation in Automotive PEM Fuel Cells  The Effect of Voltage Cycling on Catalyst Degradation in Automotive PEM Fuel Cells
Durability and cost are the two major remaining challenges for the commercialization of fuel cells in passenger vehicles. The platinum catalyst is one of the most expensive components in a fuel cell and degrades during normal operation due to load cycling. While a reduction in platinum loading is beneficial for cost, it affects catalyst durability negatively. Therefore, an understanding of the catalyst degradation mechanism is required to increase fuel cell lifetime and lower cost. In this dissertation, the conditions that promote catalyst degradation in an automotive context and its consequences on catalyst layer microstructure are studied experimentally. In order to degrade the platinum catalyst during fuel cell operation square wave voltage cycling in hydrogen-air atmosphere is carried out as an accelerated stress test on small scale single cells. For characterization of aged samples and visualization of the degradation mechanism electrochemical techniques as well as electron microscopy are ...

In most cases, a battery-powered vehicle is almost 3 times more efficient. One can only presume why automakers have been stuck trying to make it happen anyway, but the technology conveniently needs a similar (and profitable) refinery and refuelling supply chain as the gasoline model. Could that be it?. The only real advantage fuel cells *currently* have over batteries is refueling speed which is quickly being closed by Teslas Supercharger and other DC fast charging technology.. The automakers who are pushing fuel cell are also primarily located in Japan and Korea where governments are offering subsidies for the vehicles and financing for the required infrastructures. These incentives extended to the US where in California, the latest version of the Clean Vehicle Rebate Program offers bigger incentives to fuel cell cars than to electric vehicle.. Though CARBs logic for the favoritism is that no one is buying fuel cell cars anyway, so even with bigger incentives per vehicle, they will still ...

Fuel cell membranes & membrane process technology - BWT Best Water Technology  Fuel cell membranes & membrane process technology - BWT Best Water Technology
In fuel cells, hydrogen and oxygen, separated by a proton-conductive membrane impermeable to gas, bond to water, from which energy is generated as a "by product" in a process that is efficient and totally free of emissions. No intermediate stages occur as the chemical energy is converted directly into electrical energy and heat in the electrochemical process. The fuel cell is therefore a highly efficient energy converter, a form of energy generation ideally suited to the demands of the 21st century, as it emits no harmful greenhouse gases while producing simple, plain water. The technology has a host of applications and has the potential to become the most important energy system of the future ...

Development of Mediated Enzymatic Fuel Cells for Operation in Blood  Development of Mediated Enzymatic Fuel Cells for Operation in Blood
The process of enzymatic catalysis of glucose oxidation releases electrons which, when harnessed to flow through a circuit, may be utilised to power devices. This principle has driven research towards the goal of providing implantable medical devices powered by the fuel and oxidant present in-vivo, namely glucose and oxygen respectively. Challenges exist in the form of efficiently converting chemical energy into electrical energy, communicating the chemical process to an electrode, achieving both these aims under physiological conditions over a sufficient period of time, and, in so doing, creating enough electrical energy to power a device. This thesis builds on, and draws from, over three decades of development in the field of biomolecular electronics. Enzyme electrode assembly methodologies are developed, compared, and analysed in order to improve catalytic current density and stability for glucose oxidation. The inclusion of carbon nanotubes and implementation of alternate crosslinking ...

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells  Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells
Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the anode catalyst is a major obstacle preventing their use. The ideal solution is to remove CO from the H2 feed gas before it reaches the catalyst. The present project develops novel external metal/graphene membranes capable of capturing CO before it enters the cell. These membranes must have strong binding to CO and weak binding to H2. Density functional theory calculations showed that CO has the strongest binding to Pt/C followed closely by Ni/C. Of these metals, nickel has a notably weaker interaction with H2. Addition of boron, nitrogen or oxygen dopants to the carbon surface decreases CO binding and causes H2 binding to become negligible. Recent experimental studies measured the potential desorption of CO and H2 from platinum and nickel nanoparticles

NEC has succeeded in reducing the size of a prototype fuel cell for laptop use with but says it is unlikely to become commercially viable until 2007 - two years later than recent predictions - because of legal hurdles. Direct methanol fuel cells (DMFC) mix methanol with air and water to produce electrical power and are viewed by many as a potential successor to lithium-ion and other batteries used in devices such as laptops and other portable electronics devices. Their by-products are heat and water. NECs new prototype has a power unit that is 20 percent smaller than the companys previous prototype and has an output density of 70 milliwatts per square centimeter, the company said. The new fuel cell also includes a control system that helps optimise power output. It will be officially unveiled tomorrow at World PC Expo in Tokyo. A single 250 cubic-centimeter methanol fuel cartridge can provide enough power to run a notebook PC for 10 hours, said NEC. The prototype machine is based on a 1.1GHz ...

Preparation and cell performance of tubular cathode for direct methanol fuel cell - ePrints - Newcastle University  Preparation and cell performance of tubular cathode for direct methanol fuel cell - ePrints - Newcastle University
A tubular cathode was prepared by subsequently dipcoating the gas diffusion layer, Pt/C catalyst layer and Nafion membrane on the outside of the tubular Ti mesh. The single direct methanol fuel cell composed of the above electrodes was discussed under normal pressure, and the factors that affected the cell performance were discussed. The results also show that the diffusion layer and catalyst layer prepared by dip coating have mesoporous microstructure which is beneficial to mass transport. With catalyst loading increasing, the cell performance improves. When the Pt loading on cathode is 4.3 mg/cm2, the power density of DMFC reaches 12.3 mW/cm2 at room temperature by using air as the cathode feed. With the oxygen as the cathode feed, the power density of DMFC can reach 40.0 mW/cm2 at 60°C. This indicates that the temperature and oxidant type are as important as the cathode catalyst loading. The stability test of the cell after working for 100 h shows that the tubular cathode has a perfect ...

The cost of carbon dioxide abatement from state renewable portfolio standards  The cost of carbon dioxide abatement from state renewable portfolio standards
Downloadable (with restrictions)! Renewable portfolio standards (RPSs) have become a popular tool for state governments to promote renewable electricity generation and to decrease carbon dioxide emissions within a state or region. Renewable portfolio standards are a policy tool likely to persist for many decades due to the long term goals of many state RPSs and the likely creation of a federal RPS alongside any comprehensive climate change bill. Even though RPSs have become a popular policy tool, there is little empirical evidence about their costs. Using the temporal and regional variation in RPS requirements, I estimate the long-run price elasticity of supply of renewable electricity generation to be 2.67 (95% CI of 1.74, 3.60). Using my preferred elasticity estimate, I calculate the marginal cost of abatement from RPSs is at least $11 per ton of CO2 compared to a marginal cost of abatement of $3 per ton in the Regional Greenhouse Gas Initiative.

Up until now, the issue of using hydrogen fuel cells as alternative sources of power has been a matter of debate. They required fossil fuels for production, needed external inputs of electricity to operate, and were too expensive to be considered as an all-encompassing solution to the global climate crisis. Enter the mighty microbe and a team of brilliant US researchers to provide a little hope for hydrogen.. An article recently published in the National Academy of Sciences describes the newly developed "MEC", or Microbial Electrolysis Cell which generates its own hydrogen without the aid of external electricity. Through a process called Reverse Electrodialysis, the cell uses fresh and saltwater membranes to generate and collect power from charged particles created between the gradients. In addition, the microbes manufacture hydrogen gas and small amounts of electricity by breaking down organic material.. This technology has implications far beyond transportation.

The report documents the study on a hydrogen proton exchange membrane (PEM) fuel cell powered unmanned aerial vehicle (UAV) named Kenyalang-1. Common aircraft utilize internal combustion engines (ICE) as main power source for the propulsion system. However, ICE imposes negative impact towards the environment due to the pollution produced through carbon emission, initiating green house effect, global warming, and health problems. Researchers have started to develop interest on the possibilities of using alternative energies to replace ICE aircraft propulsion system. Due to the relatively new nature of the technology, there is a need for a research on the development of a ftiel cell electrical propulsion system. The objectives of this project are to design and to develop a fuel cell propulsion system that operates using a 500 W hydrogen PEM fuel cell as the main power generator for a UAV. The research is important to determine the capability of the propulsion system to power a custom designed and ...

Organic-inorganic hybrid membranes, as promising direct methanol fuel cell membranes, have become a research focus in recent years. Wherein interfacial morphology, greatly influenced by the polymer chain flexibility and interfacial stress generated during membrane formation, is a critical determinant of efficient suppression of methanol crossover. In this study, a novel and feasible approach for rational fabrication of organic/inorganic hybrid direct methanol fuel cell (DMFC) membrane is tentatively explored. By adding plasticizer in the membrane casting solution and/or elevating solvent evaporation temperature during membrane fabrication, the glass transition temperature (Tg) and crystallinity of the chitosan/zeolitehybrid membrane are both remarkably decreased. In particular, the interface voids are substantially eliminated, generating a more desirable interfacial morphology and consequently leading to an improved performance in suppressing methanol crossover. The chitosan/mordenite/sorbitol ...

In spite of the fact that electricity production in Poland was traditionally based on the huge Polish hard coal mining, the Polish government in early seventies decided to introduce nuclear power to domestic electricity balance. In 1972 the site for the first nuclear power plant was selected, and by 1984 eight different localities were examined for the next two nuclear power stations.. In 1974 an agreement on co-operation in the field of nuclear power was signed between Poland (at that time the Polish Peoples Republic) and the Soviet Union. For the first Polish nuclear power plant four VVER-440/213 units based almost entirely on Soviet supplies were chosen, and cooperation of that plant with already existing water-pumping station on Zarnowiec Lake on the Baltic Sea, was predicted. The final Decision to start construction of the first plant in Zarnowiec was taken by the Council of Ministers in January 1982, and was followed by the construction contract between Polish and Soviet governments ...
