    摘要： In an air supplier particularly for air supply systems for fuel cells including a compressor having a housing with a radial diffuser and including a rotor operated by an electric motor, a diverting channel is connected to the radial diffuser providing a communication path guiding the air via an axial annular channel to an inwardly extending collecting chamber via a final diffuser formed by a curved end section of a wall delimiting the annular passage and an inwardly curved wall area of the collection chamber, the compressor housing having an outer diameter is not substantially larger than the outer diameter of the electric motor.

    摘要： A fuel cell system has at least one fuel cell, a hydrogen storage tank in which hydrogen is stored at a pressure above atmospheric and which communicates via a hydrogen supply line with an anode chamber of the fuel cell. An anode circuit, via which unreacted hydrogen is able to be recirculated from a region downstream of the anode chamber into the hydrogen supply line, is provided. At least one pumping device is provided between the outlet of the anode chamber and its inlet in the anode circuit and/or the hydrogen supply line. Between the hydrogen storage tank and the anode chamber, a turbine is provided, which supplies at least a portion of the power required for driving the pumping device.

    摘要： In an air supply unit for a fuel cell stack comprising a compressor for compressing air that is fed via a feed line to the fuel cell stack and to a turbine to which also exhaust gas of a combustion chamber can be supplied and wherein an exhaust gas from the combustion chamber is supplied to the turbine, the feed line to the fuel cell stack is in communication with a branch line by way of which compressed air can be fed also to the combustion chamber. The invention further relates to a method for operating an air supply unit for the fuel cell system.
