Abstract
A fuel cell system and method for supplying electrical devices with electric energy in a vehicle wherein, to increase the efficiency of the power generation, the fuel cell system is supplied with atmospheric oxygen from the compressed air system. Additionally, a compressed air reservoir or a compressor for ambient air is provided in order to supply the fuel cell system with atmospheric oxygen.
Claims14
A fuel cell system for supplying electrical energy to element devices in a motor vehicle, having a braking system comprising:
- a fuel cell arrangement;
- a fuel source connected by a supply line to said fuel cell arrangement;
- and
- a vehicle compressed air system for providing air to said braking system of said vehicle wherein said vehicle compressed air system is also connected to a second supply line for providing atmospheric oxygen to said fuel cell system arrangement.
A method for supplying electrical energy to a vehicle comprising:
- providing a fuel cell arrangement;
- connecting said fuel cell arrangement to a fuel source;
- and
- connecting said fuel cell arrangement to a compressed air system of the vehicle wherein said compressed air system supplies compressed air to a braking system of said vehicle and wherein said connection to said fuel cell supplies the fuel cell arrangement with atmospheric oxygen.
A fuel cell system for an automobile having a brake system, comprising:
- a source of hydrogen connected to a plurality of fuel cells;
- an automobile compressed air source which supplies air to said brake system and is also connected to feed atmospheric oxygen to said plurality of fuel cells.
A fuel cell system for supplying electrical devices in a motor vehicle, comprising:
- a fuel cell arrangement;
- a fuel source connected by a supply line to said fuel cell arrangement;
- and
- a vehicle compressed air system connected to said fuel cell arrangement and driven by an internal combustion engine.
A method for supplying electrical energy to a vehicle comprising:
- providing a fuel cell arrangement;
- connecting said fuel cell arrangement to a fuel source;
- and
- connecting said fuel cell arrangement to a compressed air system driven by an internal combustion engine.
