الملخص
(EN)

The invention relates to a double layer cathode for molten carbonate fuel cells, containing a first layer (2a) consisting of a first cathode material, preferably lithium-treated nickel oxide, and a second layer (2b) consisting of cerium-activated lithium cobaltite. The inventive double layer cathode is characterised in that the polarization resistance is less dependent on temperature and in that it has a longer life. The double layer cathode is especially suitable for operating a fuel cell at less than 650° C. The material for the second cathode layer (2b) is produced by activating cobalt oxide by co-precipitation with cerium and treating it with lithium carbonate to form a suspension. Said suspension is then applied to the first cathode layer (2a) as a second cathode (2b), dried and sintered at a high temperature.
