First Introduction and background, experiment, simulation, lastly conclusion.

The stability of MCFC electrodes Cathode Schematic diagram of MCFC degradation according to operating time Reduction of NiO dissolution by increasing the basicity of the electrolyte or by incorporation of basic oxides into NiO the dissolution of the NiO in the fuel cell cathode environment(about 10-15ppm) can be a major life-limiting factor for the MCFC Development of new stable cathode materials LiCoO2-coated NiO Variation of the Ni amounts in the matrices with the LiCoO2 amounts in the cathodes after 10:00h operation The variation of the specific electrical conductivity of ternary compositions with LiCoO2 content, at 650℃ These are my contents. First Introduction and background, experiment, simulation, lastly conclusion.

The stability of MCFC electrodes DIR-MCFC anodes (DIR : Direct Internal reforming) Deactivation of the steam reforming catalysts by alkali carbonate electrolytes : catalysts with high alkali-tolerance Deactivation of steam reforming catalysts by coke formation : anodes for DIR-MCFC with reduced coke formation SRM (Steam Reforming of Methane) (commonly used as catalysts Ni and Ru, Rh, Pd, Ir and Pt) SRE (Steam Reforming of Ethanol) (nickel based catalysts usually supported) Evaluation of supports on the basis of their resistance to alkali poisoning, coke formation and sintering of supported Ni catalysts for DIR-MCFC Coke formation over different supported catalysts These are my contents. First Introduction and background, experiment, simulation, lastly conclusion.
