Carbon monoxide removal from hydrogen feed to fuel cell

Abstract From the Canadian patent

A process and system for providing a hydrogen-containing gas stream to a fuel cell, anode that includes providing a hydrogen-containing gas stream that includes carbon, monoxide, introducing the hydrogen-containing gas stream into a pressure swing adsorp-, tion module that includes at least one carbon monoxide-selective adsorbent to produce a, purified hydrogen-containing gas stream and introducing the purified hydrogencontaining, gas stream to the fuel cell anode. The pressure swing adsorption module can also include a, second adsorbent and/or catalyst. A reforming or partial oxidation system can produce the, hydrogen-containing gas stream.
