Fuel cell system with device for cathode inlet air preheating

摘要

The system has a heat exchanger (12), via which cathode inlet air is supplied to a fuel cell or a fuel cell stack (14). A heat exchanger (18) is provided, via which the cathode inlet air is supplied from the heat exchanger (12) to the fuel cell or the fuel cell stack and via which the afterburner exhaust gas is supplied to the heat exchanger (12) so as to form the mixture, to enable heat exchange between the afterburner exhaust gas and the cathode inlet air using the heat exchanger (18).
