Abstract

The invention provides a process for producing the cathode layer of a molten-carbonate fuel cell in which the cathode layer is present in a layer arrangement with a matrix layer and an anode layer. A porous cobalt or iron layer is filled with lithium carbonate, the cobalt or iron layer is oxidized at a temperature below the melting point of the lithium carbonate in an oxidizing atmosphere to form a cobalt oxide or iron oxide layer, and subsequently, after the temperature is increased above the melting point of the lithium carbonate, the cobalt oxide or iron oxide is reacted with the molten lithium carbonate to form lithium cobaltite or lithium ferrite.
