Abstract
A motor vehicle having a unit, particularly a drive assembly, which is operated by a fuel that is cryogenically stored in a vehicle tank, is provided, in which fuel is heated by a heat exchange with a warmer medium. The fuel taken from the vehicle tank comes in contact with the cold side of a thermoelectric generator, particularly in the form of a Seebeck element, in order to generate electric current for the electric power supply of the vehicle. The warm side of the thermoelectric generator is preferably acted upon by the warmer medium also used for the heat exchange with the cold fuel, in which case the thermoelectric generator may be integrated in a heat exchanger for the heat exchange between the fuel taken and the warmer medium.
