The fuel cell system of a motor vehicle has a fuel cell, comprising an anode side and a cathode side, a compressor, which is rotationally connected to a motor and connected by a feed line to the cathode side of the fuel cell, and a turbine, which is connected by an exhaust air line to the cathode side and which furthermore is rotationally connected only to a generator, which is connected at the output side to a second inverter and a low-voltage battery.

Motor vehicle with a fuel cell

A fuel cell plug-in hybrid vehicle includes a fuel cell having an anode side and a cathode side with a compressor connected to the cathode side. An electric motor is drive-connected exclusively to the compressor. A converter is connected electrically on one side to the motor and on the other side to a high-voltage battery. A controller switches the vehicle between two different operating states. In a first operating state, the high-voltage battery supplies electrical power to the motor via the converter so that the electric motor drives the compressor. In a second operating state, an electrical voltage is supplied from a power supply system to the motor or to the converter via a power supply line. The motor can modify the amplitude of the system voltage with the modified voltage present across the converter, which converts the voltage into a DC voltage applied across the high-voltage battery.

The disclosure concerns an operating method for an electric motor vehicle with at least one electrical machine as the traction motor and with an operating element for preselecting a coasting function, wherein, if the coasting function is preselected by the driver, under predetermined conditions the operating mode is automatically changed into a coasting mode, in which neither a drive torque nor a drag torque is exerted on the wheels of the vehicle. According to the disclosure, the predetermined conditions include the conditions that the gas pedal is in a neutral position and that the current speed of the vehicle is at or is greater than a preset value. Under the predetermined conditions the operating mode is automatically changed into the coasting mode by bringing the drive train of the vehicle into a state in which the at least one electrical machine is consuming no electrical energy.
