Abstract
A conveying unit () for a fuel cell system () for conveying and/or recirculating a gaseous medium, in particular hydrogen, comprising a jet pump () driven by a driving jet of a pressurized gaseous medium, and comprising a metering valve () with a nozzle (), wherein: the conveying unit () is designed as a combined valve jet pump assembly (); the gaseous medium is fed to the jet pump () by means of the metering valve (); the jet pump () has a main body (); and the jet pump () is connected to an anode inlet () of a fuel cell (). According to the invention, a deflection and/or change of direction of the gaseous medium which flows in a flow direction VII from the jet pump () to the anode input () of the fuel cell () occurs exclusively in the deflection region (), said the jet pump () having a separate closure cover () connected to the main body (), and the deflection region () and/or the deflection- or guiding geometry of the deflection region for the gaseous medium () is formed exclusively in the component of the closing cover ().
