  • Fuel cell with control process for reactant pressure and flow
    Patent number: 7998634
    Abstract: A fuel cell system comprising a fuel cell, which generates power by supplying anode gas and cathode gas into the fuel cell, a compressor which controls the amount of the gas to be supplied into the fuel cell, and a pressure control valve which controls the gas pressure of the fuel cell and which is provided on the downstream of the fuel cell, is controlled by changing an amount of the supply gas by said compressor, and thereafter changing the opening of said pressure control valve during the transition period of the fuel cell.
    Type: Grant
    Filed: June 29, 2006
    Date of Patent: August 16, 2011
    Assignee: Honda Giken Kogyo Kabushiki Kaisha
    Inventors: Kouji Kurosaki, Jiyunji Uehara
  • Fuel cell system and process for controlling the same
    Patent number: 7297427
    Abstract: A fuel cell system comprises a fuel cell, which generates power by supplying anode gas and cathode gas into the fuel cell, a compressor, which controls the amount of the gas to be supplied into the fuel cell, and a pressure control valve, which controls the gas pressure of the fuel cell. The pressure control valve is provided on the downstream of the fuel cell. The fuel cell is controlled by changing an amount of the supply gas by the compressor, and thereafter changing the opening of the pressure control valve during the transition period of the fuel cell.
