A new type of electrochemical cell which can be used for generating electricity or in an electrolysis mode for producing gases such as hydrogen and oxygen comprises laterally spaced apart or side-by-side catalyst layers as electrodes with the gap between the catalyst layers being bridged by a solid ...

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 ...
