Definitions
- the check valve of the first jet pump is located on the outflow side in the area of a connecting line or between the connecting line and the first jet pump.
- the check valve or an additional check valve can be located on the inflow side via a first inlet in the area of a return line or between the return line and the first jet pump. In this way, it is possible to reliably prevent the delivery quantity from flowing back through the first jet pump, in particular while the first jet pump is not controlling the quantity of the propellant medium.
- a compact design of the device can be brought about by this inventive embodiment of the device.
- the second jet pump has an at least approximately identical pressure build-up potential as the first jet pump, even with a low delivery rate that approaches at least almost zero, in particular due to the geometric design of the second jet pump.
- this pressure build-up potential can be used to prevent the delivery quantity of the anode gas from flowing back through the second jet pump. The efficiency of the device and/or of the fuel cell system can thus be improved.
- a second jet pump designed for low load is operated at low load.
- a high-load jet pump which is the first jet pump
- the low-load jet pump which is the second jet pump.
- FIG. 2 shows a schematic representation of a fuel cell arrangement according to the invention with a fuel cell and a device according to a first exemplary embodiment
