Beschreibung
Zusammenfassung:	The invention relates to a conveying device (1) for a fuel cell system (31) for conveying and/or recirculating a gaseous medium, in particular hydrogen, comprising an anode path (3) and a cathode path (5), the conveying device (1) having a side channel compressor (2) located in the anode path with a housing (17), the side channel compressor (2) having an impeller (14) arranged rotatably about a first axis of rotation (4), the side channel compressors each have a gas inlet opening (20) and a gas outlet opening (22) formed on the housing (17), which are fluidically connected to one another via a compressor space (30), in particular at least one side channel (19). According to the invention, the conveying device (1) has a turbine (13) connected to the side channel compressor (2), and the side channel compressor (2) is driven at least indirectly by means of the turbine (13) located in the cathode path (5). The invention also relates to a fuel cell system (31) having a conveying device (1) according to the inventi
