Abstract
Disclosed is a delivery unit (3) for an anode circuit (9) of a fuel cell system (1) for delivering a gaseous medium, in particular hydrogen, from an anode region (38) of a fuel cell (2), said delivery unit (3) comprising at least one jet pump (4) and being at least indirectly fluidically connected to the outlet of the anode region (38) by means of at least one connection line (23, 25) and being fluidically connected to the inlet of the anode region (38) by means of an additional connection line (27). According to the invention, in addition to the jet pump (4), the delivery unit (3) comprises a recirculation fan (8) and a metering valve (6) as other components, and the flow contours of the components (4, 6, 8) for the gaseous medium and/or the components (4, 6, 8) are at least almost entirely arranged in a common housing (7).
