ABSTRACT:
A process for producing stabilized molten carbonate fuel cell porous metal anodes by impregnating a porous metallic anode in an aqueous solution having dissolved therein a water soluble salt of a structure stabilizing agent; drying the impregnated porous anode to evaporate free water and form hydrated salts of the stabilizing agent on the surface of the metal particles, further heating the impregnated dried porous anodes to dehydrate the hydrated compounds on the surface of the metal particles, and heating the porous anodes to a temperature of about 600.degree. to about 700.degree. C. in a reducing atmosphere forming particles of the stabilizing agent on the surface of the metal particles. Suitable stabilizing agents include water soluble salts of chromium, zirconium, aluminum, and mixtures thereof. The porous metallic anodes produced according to this process provide stability against sintering and creep resistance during molten carbonate fuel cell operation.
