Performance of Co Coated Nickel Cathode Prepared by Tape Casting for Molten Carbonate Fuel Cells

摘要

The Molten Carbonate Fuel Cell (MCFC) is a promising power generating system due to its high energy conversion efficiency accompanied by its low emission.However,solubility of nickel oxide cathode in' the electrolyte is one of the important problems facing the commercialization of MCFC technology.Nickel oxide reacts with the dissolved CO_2 in the electrolyte according to an acidic dissolution mechanism and dissolves in the molten carbonate during operation.Precipitates of metallic nickel have been found in the electrolyte tile much closer to the anode and this precipitate acts as a sink for further deposition of nickel particles.
