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 کاملMolten Carbonate Fuel Cell Modelling
Hybrid plants where a fuel cell and a gas turbine are combined have attracted the attention of the power system community. In this paper, a model is provided of a Molten Carbonate Fuel Cell stack and of the thermo-hydraulic equipment in which it is embedded. The model is worked out from basic physical considerations; however, it is also simple enough for simulation and control purposes. Besides...
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 کاملCopper anode corrosion affects power generation in microbial fuel cells
Non-corrosive, carbon-based materials are usually used as anodes in microbial fuel cells (MFCs). In some cases, however, metals have been used that can corrode (e.g. copper) or that are corrosion resistant (e.g. stainless steel, SS). Corrosion could increase current through galvanic (abiotic) current production or by increasing exposed surface area, or decrease current due to generation of toxi...
