Patent ID: 7556880

Claim:
A method for making a fuel cell anode, comprising the steps of: depositing a first film on a first end region of a substrate, wherein the first film is preferentially catalytically active toward substantially unreformed hydrocarbon fuel; depositing a second film on a second end region of the substrate, the second end region opposed to the first end region, wherein the second film is preferentially catalytically active toward at least one of substantially reformed or partially reformed hydrocarbon fuel, byproducts thereof, and mixtures thereof; depositing an intermediate film on a region of the substrate intermediate the first end region and the second end region, wherein the intermediate film is preferentially catalytically active toward at least one of substantially unreformed or partially reformed hydrocarbon fuel, byproducts thereof, and mixtures thereof; and biasing inclusion of nickel toward the second film, wherein each of the first, intermediate, and second films has as a main component thereof a nickel-samaria doped ceria cermet.
