Abstract
Abstract Disclosed herein are ribbed catalyst-coated solid-state electrolyte sheets as well as a method for producing such sheets. Also disclosed is a fuel cell reactor comprising a plurality of said sheets stacked one upon another and cemented together to form a monolithic structure. Novel reactions utilizing the reactor to produce useful chemical oxidation products and/or electricity are set forth. Also disclosed is a novel wiring system to collect electrical power generated by the reactor.
