ABSTRACT:
A fuel cell system comprising a plurality of fuel cells, in particular in the form of low temperature fuel cells, which are assembled into a stack, the system having a cathode side with a cathode inlet and a cathode outlet, with oxygen or an oxygen containing gas, such as for example air, being capable of being supplied to the cathode inlet and also having an anode side which has an anode inlet and an anode outlet, with hydrogen or a hydrogen rich gas being capable of being supplied to the anode inlet and with a feedback loop being provided in order to return at least a part of the hydrogen containing exhaust gases which arise at the anode outlet back to the anode inlet, characterized by a line which leads from the anode side to the cathode side and is designed to supply anode exhaust gases to the cathode inlet which, after reaction of the hydrogen component with oxygen at the cathode side to form water, leave the fuel cell system with the cathode exhaust gases via the cathode outlet.
