PROCESS FOR PRODUCING LiCoO2 COATED AIR-ELECTRODE FOR MOLTEN CARBONATE FUEL CELL

摘要

PURPOSE: Provided is a process for producing a LiCoO2 coated air-electrode for a molten carbonate fuel cell(MCFC), which can prevent NiO, being a main material of the air-electrode, from dissolving in an electrolyte, therefore, can produce the air-electrode having long lifetime than the conventional air-electrode for the MCFC. CONSTITUTION: The process for producing the LiCoO2 coated air-electrode for the MCFC comprises the steps of: dissolving lithium salts and cobalt salts in water; adding a chelate agent such as polyethylene glycol to the produced water solution to produce sol; soaking a NiO electrode for the MCFC in the produced sol and forming gel on the surface of pores of the electrode; drying and calcining the electrode. And another process for producing the LiCoO2 coated air-electrode for the MCFC comprises the steps of: dissolving the lithium salts and cobalt salts in a solvent; impregnating the pores of the NiO electrode with the solution; drying and calcining the electrode.
