hydrogen fuel cell
31Hydrogen technologies — are technologies that relate to the production and use of hydrogen. Hydrogen technologies are applicable for many uses.Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen …
32Hydrogen storage — describes the methodologies for storing H2 for subsequent use. The methodologies span many approaches, including high pressures and cryogenics, but usually focus on chemical compounds that reversibly release H2 upon heating. Hydrogen storage is a …
33Stanley Meyer's water fuel cell — Perpetual motion machine name=Stanley Meyer s Water fuel cell topics=Physics and engineering claims= The device is designed to produce hydrogen and oxygen, from water using electricity, by a method other than water electrolysis. origyear= 1989… …
34Direct-ethanol fuel cell — Direct ethanol fuel cells or DEFCs are a subcategory of Proton exchange fuel cells where the fuel, ethanol, is fed directly to the fuel cell. Contents 1 Advantages 2 Reaction 3 Issues 4 …
35Hydrogen codes and standards — are codes and standards (RCS) for hydrogen fuel cell vehicles, stationary fuel cell applications and portable fuel cell applications.Codes and standards have repeatedly been identified as a major institutional barrier to deploying hydrogen… …
36Metal hydride fuel cell — Metal hydride fuel cells are a subclass of alkaline fuel cells that are currently 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… …
37Molten carbonate fuel cell — Scheme of a molten carbonate fuel cell Molten carbonate fuel cells (MCFCs) are high temperature fuel cells, that operate at temperatures of 600°C and above. Molten carbonate fuel cells (MCFCs) are currently being developed for natural gas, biogas …
38Solid oxide fuel cell — A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material and, as the name implies, the SOFC has a solid oxide, or… …
39Direct methanol fuel cell — Direct methanol fuel cells or DMFCs are a subcategory of proton exchange fuel cells in which methanol is used as the fuel. Their main advantage is the ease of transport of methanol, an energy dense yet reasonably stable liquid at all… …
40Protonic ceramic fuel cell — The Protonic ceramic fuel cell or PCFC is a fuel cell based on a ceramic electrolyte material that exhibits high protonic conductivity at elevated temperatures. PCFCs share the thermal and kinetic advantages of high temperature operation at 700… …
