A motor vehicle has a plurality of electric consuming devices and a power supply system for supplying the electric consuming devices with electric energy. The power supply system has a decentralized construction and, for supplying electric energy to at least one electric consuming device or to a group of electric consuming devices, has a fuel cell system which is electrically isolated from other power sources and which is arranged in the proximity to the assigned consuming device or group of consuming devices. The decentralized construction may have many mutually independent fuel cell systems, permitting a high-efficiency power supply.

What is claimed is: 1. A decentralized power supply system for a vehicle, comprising at least one fuel cell system and other power generators, wherein: in normal operation of the power supply system, the at least one fuel cell system is electrically isolated from the other power generators of the power supply system, is dedicated to supplying electricity to an assigned electric consuming device that is incorporated in a structural subassembly of the vehicle, and is an exclusive source of electric power supply to said assigned electric consuming device; and the at least one fuel cell system is collocated with the assigned electric consuming device, and is mounted on or in said structural subassembly of the vehicle. 2. Power supply system according to claim 1, wherein said structural component comprises at least one vehicle door on which or in which at least one fuel cell system is arranged for supplying electricity to an electric consuming device of the vehicle door, the consuming device being at least one of a window lift mechanism, an outside mirror heater and an electric mirror adjusting system. 3. Power supply system according to claim 1, comprising at least one secondary unit provided with an electric drive, on which or in which secondary unit at least one fuel cell system is arranged for supplying electricity to the drive, the secondary unit being an air-conditioning compressor. 4. Power supply system according to claim 1, comprising at least one vehicle body module on which or in which at least one fuel cell system is arranged for supplying electricity to electric consuming devices of the vehicle body module. 5. Power supply system according to claim 1, wherein the fuel cell system comprises at least one fuel cell and an assigned fuel supply system for the at least one fuel cell. 6. Power supply system according to claim 2, wherein said structural component comprises a vehicle seat which can be movably fastened on the vehicle and on which or in which the fuel cell system is arranged for supplying electricity to electric consuming devices of the vehicle seat selected from the group consisting of an electric seat heater and an electric seat position adjusting system. 7. Power supply system according to claim 5, wherein the fuel supply system has at least one exchangeable fuel storage device. 8. Power supply system according to claim 7, wherein said fuel storage device comprises a hydrogen cartridge. 9. Power supply system according to claim 7, wherein the fuel supply system has at least one fuel tank for accommodating a hydrocarbon-containing liquid fuel. 10. A vehicle having a power supply system according to claim 8, wherein the fuel storage device is exchangeable or fillable outside the vehicle or the component. 11. Power supply system according to claim 9, wherein the fuel supply system further comprises a reforming device for conversion of fuel to hydrogen. 12. A power supply system for an electric consuming device in a motor vehicle, comprising: a dedicated fuel cell system which, in normal operation of said power supply system, is connected as an exclusive supply of electric power to said consuming device; wherein in normal operation of said power supply system, said fuel cell system is electrically isolated from other power generators in said vehicle; and said fuel cell system is collocated with said electric consuming device, in a structural component of the vehicle. 13. Motor vehicle apparatus comprising: a component part which is mountable to a motor vehicle body; an electrically actuated device which is mounted on or in said component part; and a fuel cell system which is isolated and self contained and is mounted on or in said component part, collocated with said electrically actuated device, and is a dedicated and exclusive source of electric power supply to operate said electrically actuated device; wherein the component part is one of a vehicle door and a vehicle seat. 14. A power supply system for a vehicle having a plurality of power consumers disposed in subassemblies of said vehicle, said power supply system comprising: a plurality of individual power sources which, in normal operation of said power supply system, are electrically isolated and spatially separated from each other; wherein each of said individual power sources is connected as an exclusive source of electric power supply to a respective group of consumers, which are associated therewith; and each group of consumers is separately located in a different respective vehicle subassembly and is electrically isolated from other groups of consumers; each of said individual power sources is collocated with the group of consumers with which it is associated, within the same vehicle subassembly which contains said group of consumers with which it is associated; and said power sources comprise fuel cell units.
