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.

Arrangement for recovering water from a fuel cell battery

A water separation cell for removing the reaction water from the electrolyte of fuel cells and fuel cell batteries which comprise a liquid chamber bounded on at least one side by a porous diaphragm, and a gas chamber bounded by the diaphragm and a condensation surface adapted for cooling, in which the liquid chamber is subdivided into two chambers of different size which are arranged on top of each other with the upper, larger chamber serving as the electrolyte space and the lower, smaller chamber taking up the condensate which passes through the porous diaphragm into this chamber due to the pressure of a gas present in the gas chamber.
