(DE4322767-A1)      The vehicle has an electric drive unit (17) supplied from a fuel cell (1), with a compressor (8) in the fuel cell feed line for compressing the oxidant mass flow. The compressor is normally operated via an electric motor (10), supplied from the fuel cell, but can be operated by a starter motor (9), supplied from an electric battery (41), for starting the vehicle.    Pref. a safety procedure is initiated after starting the vehicle, before the fuel cell is started via the starter motor, the compressor motor brought into operation when the fuel cell reaches a given free-running power, with disconnection of the starter motor and switching-in of the drive unit.    ADVANTAGE -   Prevents environmental pollution by hydrogen gas and protects fuel cell from overload.    (DE4322767-C2)      The device starts a vehicle with an electric drive unit supplied with electrical power from a fuel cell (1) and with a compressor (8) for compressing the oxidant mass flow, arranged in the feed line of the fuel cell.    An electric motor (10) and a starter motor (9) are provided for driving the compressor (8), in which the starter motor (9) is supplied from a starter battery, and to electric motor (10) from the fuel cell, with voltage. After the beginning of the process, a safety inventory is carried out,and then the fuel cell is activated by the starter motor. The electromotor is activated only if the fuel cell contents have fallen to a predetermined level. The starter here is deactivated and the drive is released from the starter.    USE/ADVANTAGE -   Device and procedure for starting vehicle with fuel cells. If safety check throws up defect all following procedure steps are stopped.
