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.
Claims22
An essentially planar, fluid-impermeable ceramic sheet possessing first and second parallel surfaces on each side, said sheet possessing a plurality of essentially parallel load-bearing ribs originating in the first surface and extending generally perpendicularly therefrom to a uniform height, said ribs defining a plurality of channels for transporting gaseous materials when the sheets are stacked upon each other, said sheet composed of a solid electrolyte capable of transporting oxygen ions and wherein the channels are coated with an essentially continuous layer of an electrically conductive material for catalyzing chemical reactions in gaseous materials transported through said channels.
In an essentially planar, fluid-impermeable ceramic sheet composed of a solid electrolyte capable of transporting oxygen ions and coated with an electrically conductive material for catalyzing chemical reactions, the improvement comprising:
- a plurality of load-bearing ribs disposed in parallel on one surface of said sheet and extending generally perpendicularly therefrom, said ribs defining channels having an essentially continuous layer of said catalytic material disposed therein.
