| 摘要 |
The present invention relates to a method for operating a fuel cell system, comprising the following method steps: a) conducting a defined quantity of anode gas to an anode and conducting a defined quantity of cathode gas to a cathode, wherein a defined voltage is set at a defined current consumption and a defined power provision, wherein b) in order to increase the waste heat of the fuel cell for a defined, temporally limited duration, the fuel cell is operated in a cathode gas depletion state. Such a method provides improved thermal control of the fuel cell even in the case of coldstarting or after operation in the partial load mode. The present invention also relates to a fuel cell system.
