Abstract: A system for supplying an aircraft with inert gas is provided. The system includes at least one fuel cell with an air inlet and an exhaust air outlet as well as a membrane device with an inlet, an outlet and a vapor-permeable membrane. The exhaust air outlet is in fluid communication with the inlet of the membrane device. The membrane device guides a gas from the inlet to the outlet and to give off to the outside through the membrane any water vapor contained therein. This leads to a cost efficient, passive and reliable dehumidifaction of inert exhaust gas for inerting purposes, and a dehumidification device that does not or only marginally increases the weight of the aircraft.

Abstract: A system for the drying of exhaust gases from a fuel cell system includes two heat exchangers alternately exposed to an exhaust gas, which ice and accumulate water vapour from the exhaust gas by cooling through a coolant. A valve arrangement with a number of valves is adapted in such a manner that it operates one of the heat exchangers in an icing phase, in which the icing of water vapour is conducted, and the other heat exchanger in a regeneration phase, in which the accumulated ice melts and is extracted, in an alternating manner. This system is especially suitable in aircraft for drying an oxygen depleted exhaust gas from a fuel cell system for inerting a tank.

Abstract: A fuel cell system having an apparatus for gas drying that includes, but is not limited to at least one cooling element with at least one first surface and at least one detachment device. The cooling element is designed to be thermally connected to a heat sink and to come into contact with gas flowing past. The detachment device is movably held relative to the first surface and is designed to detach frozen water from the first surface.
