Abstract
Fuel cell batteries are provided wherein water produced during operation is quickly and easily removed even when the battery is in an inclined position. Those chambers in the fuel cell battery from which water is to be removed are each interconnected two times. One discharge point is provided for each lower corner point of the battery, whereby two of the discharge points arranged at one battery extremity are connected respectively to one of the two terminal chambers. The discharge points are connected via media lines to at least one charging valve. One valve is arranged in each media line. An inclination sensor is arranged on the battery parallel to the longitudinal and transverse axis of the battery and is connected via a control line to a control unit which is connected to the valves.
