Abstract
A hydrogen recirculation blower is used in a hydrogen return arrangement in a fuel cell system. The blower includes a rotatable rotor with an end region on which an impeller is arranged, and a stator with coil windings and with a hydrogen barrier which is formed as a hollow body. The rotor is arranged in a cavity of the hydrogen barrier, with the hydrogen barrier running both between the rotor and the coil windings and between the impeller and the coil windings. The rotor and the stator form an electric motor for driving the impeller.
