Transport unit and fuel cell system for anode circuit of fuel cell system for transport of gaseous medium

摘要

The present invention relates to a transfer unit (3) for an anode circuit (9) of a fuel cell system (1) for the transfer of gaseous medium, in particular hydrogen, from an anode region (38) of a fuel cell (2). The unit 3 comprises at least one jet pump 4 , the conveying unit 3 being at least indirectly in fluid communication with the outlet of the anode region 38 by at least one connecting line 23 , 25 , the conveying unit ( 3 ) is in fluid connection with the inlet of the anode region ( 38 ) by a further connecting line ( 27 ). According to the invention, the transfer unit 3 comprises a recirculation fan 8 and a metering valve 6 as additional components in addition to the component jet pump 4 , a component 4 for gaseous media, The flow contours of 6 , 8 and/or the components 4 , 6 , 8 are arranged at least almost completely in the common housing 7 .
