Abstract
A vehicle has an internal-combustion engine drive and a fuel cell drive system. Liquid fuel is used to supply energy to the internal-combustion engine drive and the fuel cell system. The internal-combustion engine drive is used for starting the vehicle and for permitting its immediate movement after starting of the internal-combustion engine, as well as for heating the fuel cell system to a working temperature. After the working temperature is reached, the fuel cell is started. Subsequently, an electric driving motor, which is fed by the fuel cell system, alone or together with the internal-combustion engine drive, drives the movement of the vehicle.
