  • Fuel cell system
    Patent number: 6972159
    Abstract: A fuel-cell system, in particular for a vehicle, has a device for supplying the operating agents for a fuel cell and an electrical energy accumulator. The energy accumulator is composed of a battery and of an intermediate charge store which has a lower internal resistance than the battery. A switch is provided in the electrical connection between the energy accumulator and the fuel cell.
    Type: Grant

  • Process for operating a system for the water vapor reforming of methanol
    Patent number: 6048473
    Abstract: A process for operating a system for water vapor reforming of methanol includes a mixture preparation step for preparing a water vapor/methanol mixture from water and methanol, which mixture is subsequently introduced into a reforming reactor in a quantity which depends on the load condition of the system. According to the invention, the water vapor/methanol mixture ratio of the water vapor/methanol mixture introduced into the reforming reactor is maintained at a predeterminable desired value unaffected by short-term load changing operations, to avoid undesirable short-term increases of the CO-concentration in the reformate.
