Abstract
A thermoelectric generator includes a thermal generator to which thermal energy is provided from a heat source. In order to keep the output voltage of the thermal generator in a range suitable for charging a battery or for directly feeding into the vehicle's electrical system, the rate of heat production of the heat source and/or the cooling power of a cooling device for the thermal generator is controlled by a regulator. For this purpose, the regulator is connected to a temperature sensor which is mounted on the thermal generator. The regulator can be more cost-effectively configured than a D.C. converter between the output side of the thermal generator and the battery so that this converter can be dispensed with.

A thermoelectric generating system for a vehicle having a fuel cell and a corresponding fuel supply, the thermoelectric generating system comprising
- a thermal generator thermally coupled to the fuel cell;
- and
- a regulator coupled to the fuel supply for controlling the supply of fuel to the fuel cell so as to control a rate of heat production of the fuel cell and an output voltage of the thermal generator.
A vehicle comprising:
- at least one fuel cell;
- a fuel supply for said at lease one fuel cell;
- a thermal generator thermally coupled to the at least one fuel cell;
- and
- a regulator coupled to said fuel supply for controlling the supply of fuel to said at least one fuel cell so as to control a rate of heat production of said at least one fuel cell and an output voltage of the thermal generator.
