Abstract
A method for controlling the exhaust gas temperature of a fuel cell system, the fuel cell system including a fuel cell having an anode and a cathode, and further including a fuel supply line for supplying H-containing fuel to the anode, and an oxidant supply line for supplying O-containing gas to the cathode, and at least one discharge line for discharging anode gas and/or cathode gas from the fuel cell. The discharge line is connected by at least one humidifier with the fuel supply line and/or with the oxidant supply line in such a manner that the fuel and/or the oxidant is/are humidified with moisture from the exhaust gas. The exhaust gas temperature is controlled by changing the temperature of the fuel in the fuel supply line and/or that of the oxidant in the oxidant supply line, and by transferring heat in the humidifier from the fuel and/or the oxidant to the exhaust gas.
