Herbert C Healy, Matthew Kolodney, Alexander H Levy, John C Trocciola: Recovery of carbon dioxide from fuel cell exhaust. International Fuel Cells Corporation, William W Jones, June 14, 1988: US04751151 (47 worldwide citation)

A gaseous mixture of hydrogen and carbon dioxide is used as the fuel cell fuel or anode gas, and air is used as the oxidant or cathode gas in a nonalkaline fuel cell power plant. In feeding the fuel gas through the anode side of the fuel cell, hydrogen is removed during the electrochemical reaction ...
