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 کاملSynthesized Bimetallic Electrocatalyst for Oxygen Reduction Reaction in Polymer Electrolyte Fuel Cells
In the present study, a step by step process was applied to synthesize bimetallic electrocatalyst (Ru and Pt on VulcanXC-72R). This process can reduce the amount of platinum and increase the gas diffusion electrode (GDE) performance in the cathodic reaction of polymer electrolyte membrane fuel cells (PEMFCs). Using the impregnation by hydrothermal synthesis method, a series of electrocatalysts ...
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 کاملCatalytic Mechanisms of Sulfur-Doped Graphene as Efficient Oxygen Reduction Reaction Catalysts for Fuel Cells
Density functional theory (DFT) was applied to study sulfur-doped graphene clusters as oxygen reduction reaction (ORR) cathode catalysts for fuel cells. Several sulfurdoped graphene clusters with/without Stone−Wales defects were investigated and their electronic structures, reaction free energy, transition states, and energy barriers were calculated to predict their catalytic properties. The re...
