METHOD AND DEVICE FOR OPERATING A FUEL CELL SYSTEM WITH A RECIRCULATION BLOWER ARRANGED IN A FUEL CIRCUIT OF THE FUEL CELL SYSTEM

摘要

In a method for operating a fuel cell system having recirculation blower arranged in a fuel cell circuit, fuel discharged from the anode exhaust is fed back to the inlet side of the fuel cell system via the recirculation blower. The direction of flow in the fuel return line is reversed in at least a portion of the return line, in an alternating manner.
