Abstract
A fuel cell system including: a fuel cell stack; a cathode gas supply system including a cathode supply path for feeding cathode operating gas into the fuel cell stack and a cathode exhaust gas path for discharging cathode exhaust gas out of the fuel cell stack, and a fuel cell cooling system for cooling the fuel cell stack including a coolant path into which the fuel cell stack is integrated so as to transfer heat is provided. It is provided that the cathode gas supply system also includes a turbine arranged in the cathode exhaust gas path, and the coolant path of the fuel cell cooling system in the flow path of the cathode exhaust gas downstream from the turbine is in heat-transferring contact with the cathode exhaust gas path. This achieves a cooling of the coolant by the cathode exhaust gas and a heating of the cathode exhaust gas by the coolant.
