  • Fuel cell system with recombiner
    Patent number: 7413820
    Abstract: A fuel cell system, which may include a fuel processing subsystem for converting hydrocarbons into a hydrogen-rich gas, is designed so that at least some of the components of the fuel cell system are contained inside at least one housing. The housing contains a recombiner to convert hydrogen and oxygen into water. The housing may also contain a temperature sensor in the vicinity of the recombiner.
    Type: Grant

    Date of Patent: August 19, 2008
    Assignee: NuCellSys GmbH
    Inventors: Stefan Boneberg, Bernd Monzel, Thomas Stark
  • Fuel cell system and method for operating the fuel cell system
    Patent number: 6884532
    Abstract: A fuel cell system having a fuel cell unit and a means for detecting hydrogen leaks in the fuel cell system. The fuel cell system comprises components which operate at an elevated temperature and are accommodated in a gas generation system box. The gas generation system box is connected to a suction line of a pump, which has a gas sensor arranged therein.
