A method and apparatus for selectively oxidizing carbon monoxide in a hydrogen rich feed stream. The method comprises mixing a feed stream consisting essentially of hydrogen, carbon dioxide, water and carbon monoxide with a first predetermined quantity of oxygen (air). The temperature of the mixed feed/oxygen stream is adjusted in a first the heat exchanger assembly (20) to a first temperature. The mixed feed/oxygen stream is sent to reaction chambers (30,32) having an oxidation catalyst contained therein. The carbon monoxide of the feed stream preferent...
In a method of operating a H2-O2 fuel cell system comprising the principal steps (1) providing a hydrogen-rich fuel gas having a carbon-monoxide content sufficient to poison the fuel cell\s catalyst, (2) subjecting said fuel gas to a CO+H2O shift reaction to produce a feed stream consisting essentially of hydrogen, carbon dioxide, water and less than about one percent by volume carbon monoxide, and (3) introducing said feed stream into said fuel cell, the improvement comprising after said shift reaction and before introducing said feed stream into said f...
