Classification: CPC B  H  Y | IPC B  H

Claim 9:
10. A fuel cell system, comprising:
one or more fuel cell system components, including at least one of: a cathode subsystem, an anode subsystem, a cooling circuit, an oxidizing agent feeder, and a fuel recirculation feeder; and
a controller configured to actuate the one or more fuel cell system components so as to:
determine a maximum dynamics requirement for the motor vehicle coming out of an idling mode in which a fuel cell system of the motor vehicle does not provide electricity for a driving operation of the motor vehicle to an electric engine, wherein the maximum dynamics requirement corresponds to a maximum power change rate required during operation coming out of the idling mode, wherein the maximum dynamics requirement is determined from among a first maximum dynamics requirement and a second maximum dynamics requirement, wherein lower maximum power change rates are required for the first maximum dynamics requirement than for the second maximum dynamics requirement; and
adapt operation of the fuel cell system of the motor vehicle during the idling based on the maximum dynamics requirement, such that: (a) when the maximum dynamics requirement is the first maximum dynamics requirement, the fuel cell system is adapted to operate in a first idling operation mode, and (b) when the maximum dynamics requirement is the second maximum dynamics requirement, the fuel cell system is adapted to operate in a second idling operation mode, wherein the fuel cell system is operated more efficiently in the first idling operating mode than in the second idling operation mode.
