  • Enclosed separator unit for a gas supply of a fuel cell system
    Patent number: 8835062
    Abstract: An enclosed separator unit for incorporation into a gas supply device of a fuel cell system, to separate liquid from the gas supply device, includes a separator for separating the liquid. A housing encloses the separator unit which is arranged in a gas space 21 in the housing and/or is in thermal contact with the gas space. A line system is provided for discharging the liquid from the separator, and at least one fluid dynamically active functional component is arranged in the line system, in the gas space 21.

  • Heating Device For Condensate Trap
    Publication number: 20100096378
    Abstract: A device which ensure functionality of a vehicle fuel cell system, even at temperatures of below freezing point, includes at least one heating element arranged in the area of the condensate trap of the fuel cell in such a way that any ice present is heated locally. As a result, one or more melted channels form, through which water may flow after only a very short thawing process.

  • Fuel cell system and method for operating the fuel cell system
    Patent number: 6723460
    Abstract: A fuel cell system has a fuel cell unit with at least one fuel cell and a gas generation system, which supplies the fuel cell unit with hydrogen from an operating medium, and at least one ion exchanger unit for removing ions from water. The at least one ion exchanger unit is arranged in a flow path for the operating medium, between a condensate separator and the gas generation system and is acted on by a mixture of water and the operating medium.
