Abstract

The subject of the invention is a method for manufacturing a cathode for a molten carbonate fuel cell by oxidation of a porous precursor electrode and contact with molten carbonate. The precursor electrode, following assembly of a layered arrangement that contains the precursor electrode, a matrix layer made of molten carbonate, and a porous anode, with a presettable curve for the current density, is oxidized anodically and doped by contact with molten carbonate.
