Electrode for fuel cell

DETAILED DESCRIPTION What is claimed is: 1.
A fuel cell having an electrolyte of solid, fritted ceramic, suitable for operation at high temperatures and for operation on a hydrocarbon or hydrogen as a fuel and oxygen or oxygen containing gas as a comburant, consisting essentially of an electrolyte of a cubic-phase stabilized zirconia, a cathode, and an anode therefor, said anode being porous and consisting essentially of an electron collector wherein said collector is selected from the group consisting of cubic-phase stabilized zirconia modified with a uranium oxide, silver and copper and an oxidation catalyst wherein said catalyst is selected from the group consisting of silver and oxides of chromium, and vanadium.
2.
The fuel cell according to claim 1, wherein the oxidation catalyst is as a layer on the electron collector.
3.
The fuel cell according to claim 1, wherein the oxidation catalyst is dispersed through the electron collector.
4.
A fuel cell having an electrolyte of solid, fritted ceramic, suitable for operation at high temperatures and for operation on a hydrocarbon or hydrogen as a fuel and oxygen or oxygen containing gas as a comburant, consisting essentially of an electrolyte of a cubic-phase stabilized zirconia, a cathode, and an anode therefor, said anode being porous and consisting essentially of an electron collector which is silver and an oxidation catalyst which is a mixture of silver and chromium oxide.
5.
The fuel cell according to claim 1, wherein the electron collector is copper.
6.
In a method for electro-chemical combustion of hydrogen or a hydrocarbon in the presence of oxygen, consisting of combusting said hydrocarbon in a fuel call having as an electrolyte a cubic-phase stabilized zirconia, a cathode, and an anode, the improvement comprising conducting said combusting of said hydrocarbon at said anode of said fuel cell wherein said anode is selected from the group consisting of cubic-phase stabilized zirconia modified with a uranium oxide, silver and copper and an oxidation catalyst for said hydrocarbon, said anode being porous, whereby substantially no carbon deposits are formed at said anode when said fuel cell is operated with methane as the fuel, said oxidation catalyst is selected from the group consisting of chromium oxide, silver, vanadium oxide
