Abstract
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.
