Patent ID: 10727508

Abstract:
The disclosure relates to a fuel cell system comprising a fuel cell stack comprising anode chambers and cathode chambers, an anode supply comprising an anode supply path for supplying an anode operating gas to the anode chambers, and an anode exhaust path for discharging an anode exhaust gas from the anode chambers, and a cathode supply comprising a cathode supply path for supplying a cathode operating gas to the cathode chambers and a cathode exhaust path for discharging a cathode exhaust gas from the cathode chambers, and comprising a negative-pressure generation means for generating a negative pressure in the cathode chambers. It is provided that the negative-pressure generation means is designed as an ejector which is connected to a compressor arranged in the cathode supply path on the pressure input side, and to the cathode chambers of the fuel cell stack on the suction side, in a fluid-conducting manner.
