A process is described for treatment of molten carbonate fuel cell porous metallic anodes to produce stabilized molten carbonate fuel cell porous metallic anodes comprising the steps of: impregnating a porous metallic anode comprising principally metal particles selected from the group consisting of: copper, cobalt, nickel and alloys and mixtures thereof, in an aqueous solution having dissolved therein a water soluble salt of a structure stabilizing agent; drying the impregnated porous anode at temperatures of about 80/sup 0/C to about 100/sup 0/C evaporating free water to form hydrated salts of the stabilizing agent on the surface of the metal particles; heating the impregnated dried porous anodes to a temperature of about 110/sup 0/C to about 160/sup 0/C, dehydrating the hydrated compounds on the surface of the metal particles; and heating the porous anodes to a temperature of about 600/sup 0/C to about 700/sup 0/C in a reducing atmosphere forming particles of the stabilizing agent in reduced form on the surface of the metal particles.
