Abstract (en)

[origin: WO2008028439A1] The invention relates to a fuel cell system having a fuel cell stack (10), an afterburner (12) for burning off gas emerging from the fuel cell stack, and a heat exchanger (16) which is arranged in an off-gas passage (14) from the afterburner and in which cathode supply air (18) to be supplied to the fuel cell stack can be heated. The invention provides for the capability to supply cathode supply air (20) to the fuel cell stack (10) without previously having been heated in the heat exchanger (16), and for the capability to use the total amount of cathode supply air supplied as well as the ratio of the component of the cathode supply air (18, 20) that has been heated in the heat exchanger and of that which has not been heated in the heat exchanger to influence the thermal and temperature budget of the fuel cell stack (10). The invention also relates to a method for influencing the thermal and temperature budget of a fuel cell stack.
