Abstract
A fuel cell system includes at least one fuel cell having an anode chamber, a cathode chamber, a hydrogen pressure reservoir, a recirculation line connecting an outlet of the anode chamber to an inlet of the anode chamber, a recirculation conveyor with a compressor wheel in the region of the recirculation line, and a turbine for expanding the hydrogen that is under pressure before entry into the anode chamber. The recirculation conveyor is driven at least partially by the turbine. The turbine and the compressor wheel are formed in one component.
