Abstract
The present invention is directed to a method for forming porous oxide dispersion strengthened molten carbonate fuel cell anodes having improved anode creep resistance. The method comprises the steps of forming an alloy powder comprised of a base metal and an alloy metal, forming the alloy into a porous anode structure by sintering, and then placing the porous anode structure under conditions in which the base metal is reduced and the alloy metal is oxidized, thereby internally oxidizing the alloy metal to form oxide particles therein. Alternatively, the method of the present invention can comprise the steps of forming an alloy powder comprised of a base metal and an alloy metal, placing the alloy powder under conditions wherein the powder is oxidized only on its surface, thereby forming oxides of both the base metal and the alloy metal, and forming the oxidized alloy powder into a porous anode structure by simultaneous sintering and internally oxidizing the remaining unoxidized alloy metal by an oxygen exchange reaction between the base metal oxide the internal alloy metal.
