  • Fuel cell block including a water separator
    Patent number: 7338728
    Abstract: A fuel cell block includes a plurality of channels and pipings and a resulting plurality of connecting and sealed points. Vibrations of the fuel cell block, particularly in vehicles, lead to stress and fatigue of sealed points. This causes a safety problem during operation of the fuel cell block. In order to solve the problem, the fuel cell block includes an end plate, an operating material channel that goes through the end plate and an operating material control device arranged at least partly in the operating material channel. The operating material control device is integrated at least partly into the end plate.
