(WO9418713-A1)      Molten carbonate fuel cell comprises a matrix layer impregnated with a Li2CO3-contg. molten electrolyte provided on one side with a porous anode layer and on the other side with a porous cathode layer of Li-cobaltite or Li-ferrite.    The novelty is that the cathode layer is formed by filling a porous Co or Fe layer with Li2CO3, oxidising this layer in an oxidising atmosphere to give a Co-oxide or Fe-oxide layer filled with Li2CO3 at a temp. below the m.pt. of the Li2CO3, raising the temp. above the m.pt. of the Li2CO3, and reacting the Co-oxide or Fe-oxide with Li2CO3 to Li-cobaltite or Li-ferrite.    ADVANTAGE -   The cathode layer has a longer service life.
