Disclosed is a hydrogen generation process for use with fuel cells which includes a preferential oxidation step to reduce the concentration of carbon monoxide. The preferential oxidation step includes contacting a fuel stream comprising hydrogen and carbon monoxide in the presence of an oxygen at a preferential oxidation temperature of between about 70.degree. and about 160.degree. C. with preferential oxidation catalyst for reducing the concentration of carbon monoxide to produce a treated fuel gas stream comprising less than about 50 ppm-vol carbon mon...
[ We claim:] [1.]1. A process for the generation of a hydrogen-rich fuel gas stream for use in a fuel cell for the generation of electric power, said process comprising:a) passing a feed stream comprising a hydrocarbon or an oxygenate to a fuel processor comprising an integrated reforming and water gas shift conversion zone to produce a fuel stream comprising hydrogen, carbon monoxide, carbon dioxide and water;b) passing the fuel stream at an oxidation temperature between 70.degree. and less than 160.degree. C. in the presence of an oxygen-containing str...
