Method for preparing LICOO2-coated NiO cathodes for molten carbon fuel cell

Abstract

A LiCoO2-coated NiO cathode for molten carbonate fuel cell is provided, wherein the cathode is prepared by dissolving a stoichiometric amount of lithium salts and cobalt salts in a solvent with or without adding a chelating agent to give a sol or a mixed solution, impregnating a NiO electrode for MCFC into the sol or the mixed solution, and drying and calcining the resulting electrode. By using the cathode of the invention, lifetime of the cell can be extended by two or more times while maintaining cell performance.
