  • Recovering a reactant from a fuel cell exhaust flow
    Patent number: 8158290
    Abstract: A technique includes lowering a temperature of a cathode exhaust flow from an electrochemical cell to produce a second flow and routing the second flow to a contaminant trap.
    Type: Grant
    Filed: April 20, 2007
    Date of Patent: April 17, 2012
    Assignee: Plug Power, Inc.
    Inventors: Michael Penev, Richard H. Cutright
  • Integrated high temperature PEM fuel cell system
    Patent number: 8158289
    Abstract: A fuel cell system includes a fuel cell stack that includes PEM fuel cells. Each fuel cell has an operating temperature of at least 120° C. The fuel cell stack has a cathode inlet to receive a flow of ambient air and a cathode outlet to provide a cathode exhaust flow. The fuel cell system includes a fuel processing reactor that has inlet and an outlet. The inlet and outlet are in fluid communication with a catalyst that is suitable for convening a hydrocarbon into a gas that contains hydrogen and carbon monoxide. The outlet is in fluid communication with an anode chamber of the fuel cell, and the inlet of the fuel processing reactor is in fluid communication with the cathode outlet.

  • Integrated high temperature PEM fuel cell system
    Publication number: 20020160239
    Abstract: A simplified PEM fuel cell system is integrated with a fuel processor and an exhaust gas oxidizer to ensure clean emissions. The fuel cell can have an operating temperature of 120-200° C. Cathode exhaust of a PEM fuel cell is used to provide steam and oxygen to a fuel processing reactor to convert a hydrocarbon fuel to hydrogen, wherein the hydrogen is provided to a fuel cell.
