Zusammenfassung:	A recirculation fan turbocharger assembly (23) recycles hydrogen and supplies air in a fuel cell system. The assembly (23) includes a fan (25), a compressor (27), and an electric drive (31) and/or a turbine (29). The fan (25) has an impeller (255) which is designed to convey a hydrogen containing recycle stream (250) to a fuel cell unit (1). The compressor (27) has a compressor wheel (275) which is designed to compress an air stream (270) for a fuel cell unit. The compressor wheel (275) and the impeller (255) are coupled to one another in a rotationally fixed manner. The electric drive (31) and/or a turbine (29) is/are designed to drive the impeller (255) and the compressor wheel (275) simultaneously.
