Abstract
An apparatus is used for the recirculation of anode exhaust gases of a fuel cell, with a recirculation blower and at least one jet pump operated by a propulsion gas stream. The propelling medium is in this case a pressurized fuel, for example hydrogen. The anode outlet of the fuel cell is connected to the intake connection of the at least one jet pump. The outlet of the at least one jet pump is then connected to both the anode inlet and the intake connection of the recirculation blower. The output of the recirculation blower can be connected to the intake connection of the at least one jet pump.
