摘要： In a fuel cell system a specific connection and a valve arrangement make it possible for a compressor to supply precompressed air to a fuel cell stack via a waste gas line, said air then leaving the fuel cell stack via a line which is otherwise an air feed line. In this way, a humidifier may be bypassed. This is sensible in particular during a start phase at low ambient temperatures, during which the fuel cell system is intended to warm up without moisture in the fuel cell stack having a negative effect, for instance by freezing. The compressor may be operated both in the start phase or stop phase and during conventional operation by the same mode of operation.

摘要： A fuel cell circuit of a fuel cell system includes a fuel cell unit having an input on the anode side for feeding fuel from a storage tank to the fuel cell unit, and an output on the anode side for discharging fuel cell waste gas on the anode side from the fuel cell unit. A recirculation circuit is provided, to return the fuel cell waste gas on the anode side to the input on the anode side. The recirculation circuit is connected to an intake line of an ejector unit, and fuel can be fed from the storage tank directly into the recirculation circuit.

摘要： A fuel cell supply system 6 is proposed for feeding an oxidizing agent to a fuel cell assembly 2, has a continuous flow machine for accelerating and/or increasing the pressure of the oxidizing agent, and a humidifier for humidifying the oxidizing agent. The humidifier is connected or connectable flow-wise between the continuous flow machine and the fuel cell assembly, and has a dehumidifier, which is designed and/or arranged to dehumidify the oxidizing agent.

摘要： A method of operating a fuel cell system with at least one fuel cell unit comprising a plurality of fuel cells, each having one anode and one cathode, the anode adjoining an anode gas compartment and the cathode adjoining a cathode gas compartment, hydrogen being supplied to the anode and an oxidizing agent being supplied to the cathode. Hydrogen is supplied to the anode compartment during a retention time before start-up of the fuel cell system, in which no fuel cell reaction takes place in the fuel cell unit. Hydrogen is stored in an adsorption storage element during fuel cell operation and released to the anode compartment during the retention time.
