Hydrogen generation and fuel cell operation are integrated through the use of a low-cost hydrogen generation zone which comprises a pre-reforming zone, a partial oxidation zone, a reforming zone, and a water gas shift zone. Anode waste gas from the fuel cell is burned to provide heat to pre-reform the...http://www.google.de/patents/US6299994?utm_source=gb-gplus-sharePatent US6299994 - Process for providing a pure hydrogen stream for use with fuel cells
