Ejector jet pump

Abstract

An ejector jet pump for a recirculation system of a fuel cell drive for humidifying and recirculating hydrogen in the fuel cell system, with at least one fuel cell, including a water separator for separating water and forming droplet-free gas from the moist exhaust gas of the fuel cell, and a gas delivery device arranged downstream of the water separator, wherein the water separator has a suction connection for feeding the exhaust gas into the water separator, wherein the water separator has a water outlet for discharging water separated from the moist exhaust gas, wherein the water separator has a droplet-free gas connection which opens into the gas delivery device. The water separator between the suction connection and the gas delivery device can be be tubular in shape and have a bend at an angle α. of at least 60°and at most 120°.
