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...

Exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. The proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. To generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

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...

La0.8Sr0.2CoO3 was coated on NiO (LSC–NiO) cathodes using a sol–gel method. Dissolution studies in molten Li2CO3 and K2CO3 (62:38 mol%) at 650 8C showed lower Ni dissolution than that of the conventional nickel oxide cathode. Impedance analysis showed that the behavior of the developed cathode is similar to that of nickel oxide. The LSC coated Ni cathode has an over potential of 109 mVat an app...

We determine the fundamental iron oxide high solubility mechanism that drives a new electrolytic pathway to iron production, and eliminates a major CO(2) emission source, for example it is produced using wind and solar energy, in a molten carbonate electrolyte, at a high rate and a low electrolysis energy.
