  • Publication number: 20240234876
    Abstract: The invention relates to a device for electrically connecting at least one fuel cell stack and at least one high-voltage battery for supplying electrical energy to consumers which are connected on the side of the high-voltage-battery. The invention is characterized in that the fuel cell stack and the high-voltage battery are connected to one another via at least one diode, which blocks current flow in the direction of the fuel cell stack, and at least one switch for closing and breaking the connection. According to the method, the switch is controlled depending on the voltages of firstly the at least one fuel cell stack and secondly the at least one high-voltage battery.

  • Publication number: 20230178764
    Abstract: The invention relates to an air supply device (1) for fuel cell systems (2, 3) with a flow compressor and an electric drive motor (4) for the flow compressor, wherein the flow compressor has two compressor wheels (6, 7) which are essentially symmetrical and which are arranged, together with the electric drive motor (4) there between, on a common shaft (5). The air supply device according to the invention is characterized in that the two compressor wheels (6, 7) are connected on the pressure side to two systems (2, 3, 10, 13) which are pneumatically not permanently connected. A fuel cell system (2, 3) which uses such an air supply device (1) is also claimed.
