Abstract
An apparatus and method for starting a vehicle which is driven by an electric drive unit supplied with electrical energy from a fuel cell. A compressor is arranged in the feed line of the fuel cell for the oxidant mass flow and is driven by an electric motor supplied with voltage from the fuel cell itself. For the purpose of starting the fuel cell, a starter motor is provided for driving the compressor which is fed from a 12 V starter battery. In addition, a safety interrogation is initiated before starting the vehicle. The fuel cell is not run up to a prescribed no-load power with the aid of the starter motor until successful termination of the safety interrogation. The drive unit is then released after this no-load power has been reached.
