Patent ID: 8518605

Claim:
An anode for a high-temperature fuel cell having at least one of an anode substrate and a functional anode layer comprising a porous ceramic structure having a first predominantly electron-conducting phase with the general empirical formula Sr 1-x Ln x TiO 3 wherein Ln=Y, Gd to Lu and 0.07<x<0.1, the first predominantly electron-conducting phase having an electrical conductivity of 10 to 100 S/cm at 800° C. following reduction at temperatures greater than 1300° C., and having a second predominantly ion-conducting phase component comprising yttrium or scandium-stabilized zirconium dioxide (YSZ or ScSZ) or a lanthanide-substituted cerium oxide, the volume ratio of the first predominantly electron-conducting phase to the second predominantly ion-conducting phase is in the range of 80:20 to 50:50, and a catalyst disposed on the surface of the pores of the porous ceramic structure.
