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.

Abstract: A multi-functional spacer element for spacing at least one printed circuit board from an opposite spacing surface. The spacer element can not only accomplish the spacing of one or more printed circuit boards, but can also support a fastening function to a carrier element and an electrical ground connection. A passageway extends through the main body. The spacer element includes a press-in element. The spacer element 1 includes an electrically conductive material for electrically conducting from at least a first contact surface to the press-in element.

Abstract: A reluctance machine has a stator (3) and a rotor (1). The rotor (1) comprises an encapsulated body (17), which can rotate about an axis of rotation (15) of the rotor (1), and a plurality of flow guide segments (19). The flow guide segments (19) form poles of the rotor (1), are arranged in a circumferential direction about the axis of rotation (15), and are embedded in the encapsulated body (17).
