Title of Invention

A SOLID OXIDE FUEL CELL AND PROCESS FOR PRODUCING ELECTRICAL ENERGY

Abstract The invention relates to a solid oxide fuel cell which comprises a solid electrolyte comprised of an electronic insulator which allows transfer of anions. a ceramic-melal composite anode and a cathode. The fuel cell also comprises a sulfur-containing hydrocarbon fuel having a sulfur content of from about I ppm to about 5000 ppm and an oxygen source. The invention further relates to a process of producing eleclIical energy with the fucl cell and a process of restoring the operability of a fuel cell that was deactivated by sulfur poisoning. The invention also relates to a method for preparation of a porous cermet as a direct-oxidation anode Q with supponed electrolyte structure for a solid-oxide fuel cell using a nickel cermet. The nickel cermet is leached to remove at least pan of the nickel, thereby producing a porous oxide. The resulting porous oxide is then impregnated. preferably with a salt of copper,which is calcined to CuD, then reduced to elemental copper. The resulting copper cermet or copper-nickel alloy cermet can be used as o the direct-oxidation anode. The stal1ing material for the nickel cermet is preferably a lape formed from a slurry comprising NiD and a ceramic powder comprising YSZ. This tape is combined into an assemblage with one or two additional tapes cast from a slurry > comprising a ceramic powder. The invention further relates to a solid-oxide fuel cell comprising an anode material with supported ,... electrolyte structure made by this method and a process for producing electrical energy using this fuel cell.
