Molten Carbonate Fuel Cells
Molten carbonate fuel cells use carbonate salts of alkali metals as electrolyte. Due to the highly corrosive nature of the electrolyte, various countermeasures are being developed. MCFCs are expected for high-efficiency power generation systems using hydrocarbon fuels, such as natural gas and coal gas. This article describes the mechanisms of operation and cell degradation, as well as the featu...
متن کاملMolten Carbonate Fuel Cells for Electrolysis
The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...
متن کاملAnalysis for a Molten Carbonate Fuel Cell
In this paper we analyze a planar model for a molten carbonate electrode of a fuel cell. The model consists of two coupled second-order ordinary diierential equations, one for the concentration of the reactant gas and one for the potential. Restricting ourselves to the case of a positive reaction order in the Butler-Volmer equation, we consider existence, uniqueness, various monotonicity proper...
متن کاملNickel catalysts for internal reforming in molten carbonate fuel cells
Natural gas may be used instead of hydrogen as fuel for the molten carbonate fuel cell (MCFC) by steam reforming the natural gas inside the MCFC, using a nickel catalyst (internal reforming). The severe conditions inside the MCFC, however, require that the catalyst has a very high stability. In order to find suitable types of nickel catalysts and to obtain more knowledge about the deactivation ...
متن کاملEthanol Reforming for Supplying Molten Carbonate Fuel Cells
An interesting application of agricultural renewable sources is the employment of ethanol for supplying Molten Carbonate Fuel Cells (MCFCs). For that purpose, ethanol has to be converted into hydrogen by a steam reforming process. MCFCs are particularly suitable for this kind of applications due to their high tolerability to the impurities which are contained into the reaction products and also...
