METHOD FOR REMOVING CO, H2 AND CH4 FROM AN ANODE WASTE GAS OF A FUEL CELL AND CATALYST SYSTEM USEFUL FOR REMOVING THESE GASES

摘要

A system for removing CO, H2 and CH4 from an anode waste gas stream from a fuel cell is disclosed. The two catalyst system may comprise a platinum/palladium catalyst and a copper/manganese catalyst. The anode waste stream comes in contact with the platinum/palladium catalyst prior to contacting the copper/manganese catalyst.
