  • Functional Module for a Coolant Circuit of a Fuel Cell System and Method for Producing a Functional Module and Container for a Coolant Circuit of a Fuel Cell System
    Publication number: 20150017560
    Abstract: A functional module for a coolant circuit of a vehicle fuel cell system includes a container having an ion-exchange material and a pump device for the coolant fluidically coupled to each other in such a manner that a coolant inlet and a coolant outlet of the pump device are connected to a coolant outlet and a coolant inlet of the container. The container surrounds at least one region of the pump device that has a conveying unit of the pump device at least in certain areas around the outer circumference.

  • Vehicle having at least one cooling circuit for cooling a fuel cell system
    Patent number: 8616317
    Abstract: A vehicle includes at least one cooling circuit for cooling a fuel cell system. The cooling circuit includes at least one cooling heat exchanger, a cooling medium transportation device and a heat exchanger in a fuel cell stack of fuel cell system. Cooling heat exchanger is affected by motion-related air flow as cooling air. The cooling heat exchanger is constructed in at least two stages, which are arranged in such a way that they are serially flowed through, one after another, by motion-related airflow.
