A vehicle includes an internal combustion engine and a fuel cell for supplying electric vehicle systems. The fuel cell is thermally “coupled” with the internal combustion engine. The waste heat of the internal combustion engine is used for heating the fuel cell, that is, for maintaining the operating temperature of the fuel cell. The fuel cell is arranged directly on the engine where, in the case of conventional vehicles, the transmission is arranged. The transmission is arranged in the area of the rear axle in front of the rear-axle divider transmission.
