Abstract
Thermal-shock-resistant fuel cell designs comprising flat and corrugated ceramic sheets combined to form channeled structures, the sheets being provided as thin, flexible ceramics and being particularly effective when used as components of compliant electrolyte substructures incorporating the flexible ceramics with fuel cell electrodes and/or current conductors bonded thereto, are described.
Claims14
A solid electrolyte fuel cell comprising an oxidant reservoir, a fuel reservoir, and an electrolyte structure interposed between the oxidant and fuel reservoirs, wherein the electrolyte structure includes an oxygen-ion-conductive electrolyte comprising a thin, flexible, pre-sintered, polycrystalline ceramic sheet.
A fuel cell in accordance with claim I wherein the pre-sintered polycrystalline ceramic sheet is directly bonded to an electrode or current conductor.
A thermal-shock-resistant fuel cell comprised of a combination of flat or curved and corrugated ceramic sheets forming a channeled fuel cell structure, wherein at least one of the sheets is a flexible pre-sintered ceramic sheet.
