NOVEL COMPOSITE-BASED CATHODES FOR MOLTEN CARBONATE FUEL CELLS BY ELECTROCHEMICAL MULTICOMPONENT MODIFICATION
A multicomponent modification on the surface of porous nickel with nanoparticles is conducted by an electrophoretic deposition (EPD) technique to prepare new composite-based cathodes for molten carbonate fuel cells (MCFCs). Two new ternary composite-based cathodes, (nano- LiCoO2-LiFeO2 )- Ni and (nano- LiCoO2-CeO2 )- Ni , are inclined to possess good morphology and homogeneous element distribution when prepared under moderate current density resulting from a medium deposition voltage and suspension pH value in this work. Both composite-based cathodes manifest excellent anti-deformation and anti-dissolution performances under conditions of a simulated MCFC startup stage and are thus expected to be useful for application in the MCFC industry.
