An apparatus removes carbon monoxide (CO) from a hydrogen-rich gas stream in a hydrogen fuel cell system. CO fouls costly catalytic particles in the membrane electrode assemblies of proton exchange membrane (PEM) fuel cells. A vessel houses a carbon monoxide adsorbent. The vessel may be a rotating pressure swing adsorber. A water gas shift reactor is upstream of the rotating pressure swing adsorber. The water gas shift reactor may include a second adsorbent adapted to adsorb carbon monoxide at low temperatures and to desorb carbon monoxide at high temper...
1. A system comprising a non-rotating shift reactor including a reaction region having an inlet and an outlet, a water gas shift catalyst disposed within said reaction region and extending to said outlet and a carbon monoxide adsorbent disposed within said region between said inlet and said outlet, wherein said shift reactor is adapted to receive a gas stream containing hydrogen and carbon monoxide from an upstream reactor, and wherein said adsorbent is active to adsorb carbon monoxide at substantially ambient temperature and pressure conditions and to d...
