An electric drive device for a motor vehicle has a housing, a first planetary gearset arranged in the housing and which has a first sun gear as first elements, a first planetary support, and a first gear ring. A second planetary gearset is arranged in the housing and has a second sun gear that is coupled or can be coupled non-rotationally to the first gear ring as second elements and a second planetary support and a second gear ring. The device has an electric motor, which has a stator and a rotor, an input shaft that can be driven by the rotor and is permanently non-rotationally connected to the first sun gear, an output shaft, having a differential transmission, a lateral shaft and having a first switching element, which is provided to connect the first sun gear non-rotationally to the housing. The rotor, the first planetary gearset, the second planetary gearset, and the differential transmission are arranged coaxially to one another. The lateral shaft is arranged between the differential transmission and a wheel of the motor vehicle and penetrates the rotor.

Electric drive device for a motor vehicle

A supply assembly and a fuel cell system having a supply assembly that demonstrates a cost-effective and/or resilient design in operation. A supply assembly for coupling to a fuel cell device is proposed, having a gas-to-gas humidifier that is designed and/or arranged in order to humidify the oxidation means A for the fuel cell device by means of the humidity from the exhaust gases B of the fuel cell device has an exhaust gas region and an oxidation means region that are separated from one another by a separation layer. The separation layer enables a transmission of the humidity from the exhaust gas region into the oxidation means region for humidification of the oxidation means A, wherein the gas-to-gas humidifier has a monolithic honeycomb structure for fowling the exhaust gas region and the oxidation means region.

Supply assembly for coupling to a fuel cell device and fuel cell system having the supply assembly

The invention relates to a method and a device for operating a fuel cell system () having a recirculation blower () disposed in a fuel circuit of the fuel cell system () by means of which the fuel (BS) exiting the fuel cell system () on the anode side is resupplied, said blower being driven by an air-driven drive turbine (), wherein the air-driven drive turbine () is impacted by compressed air (vL).

Method and device for operating a fuel cell system having a recirculation blower disposed in a fuel circuit of the fuel cell system

The invention relates to devices for operating fuel cells. According to the invention, the two functions 'cooling' and 'humidification' are combined in a functional unit () to adjust the temperature of the air () supplied as the reaction medium and to humidify it. Membranes () are used that consist of a temperature-resistant material.
