ABSTRACT:
A fuel cell system has a fuel cell stack composed of a plurality of fuel cells with a cathode side having a cathode inlet and a cathode outlet and an anode side having an anode inlet and an anode outlet. It is possible for a hydrogen-containing medium to be fed to the anode side and an oxygen-containing medium to be fed to the cathode side. It is further possible for at least some of the anode exhaust gas to be fed to the cathode side. An anode-side exhaust-gas line opens into an opening in a feed line for the oxygen-containing medium on a suction side of a compressor that feeds the oxygen to the cathode.
