Solid oxide fuel cells with symmetric composite electrodes

The present invention relates to an apparatus, such as a solid electrolyte fuel cell, which includes opposing, symmetric, composite electrodes including a conductive metal phase and a ceramic phase and a method of making such an apparatus. The present invention relates to electrode/electrolyte assemblies for solid oxide fuel cells (SOFCs) comprising a thin electrolyte sheet interposed between opposite electrodes, and wherein the positive air electrode (cathode) and negative fuel electrode (anode) are composed of similar electronically conductive metal phases and stabilizing ceramic phases, and wherein the anode exhibits both good oxidation resistance and good catalytic activity toward fuel oxidation.
