Abstract

The present invention relates to a compliant fuel cell apparatus which includes arrays of positive air electrodes and negative fuel electrodes with via interconnections disposed on a thin compliant electrolyte sheet; optional electrode designs include symmetric electrodes comprising a conductive silver alloy metal phase and a thermally stabilizing ceramic phase, the latter providing low interface resistance and matching thermal properties, with the resulting fuel cells remaining sufficiently compliant to demonstrate good resistance to thermal shock damage.
