| 20100035100 | Method and Apparatus for Supplying Input Gases to a Fuel Cell Stack - A fuel supply system for a fuel cell stack includes a cathode gas supply line for supplying an oxidant to the cathode input of the fuel cell stack and an anode gas supply line for supplying fuel to the anode input of the fuel cell stack. An anode gas recirculation line recirculates partially used anode gas from the anode output to the anode input while a purge line may be connected for conducting away the partially used anode gas, as a purge gas from the anode gas recirculation line into the cathode gas supply line. The supply system also includes a conditioning arrangement disposed upstream of the cathode input. The conditioning arrangement is designed to a) mix a partial flow of the oxidant with the purge gas in a mixing station, b) compress accelerate, and/or heat the partial flow or the mixed flow, and c) conduct the mixed flow into the cathode gas supply line. | 02-11-2010 |
| 20100092822 | Fuel Cell System for a Vehicle - A fuel cell system for a vehicle includes a burner for producing a heat flow by combustion of a fuel gas which reacts with an oxidant. A heating heat exchanger provided to heat a vehicle passenger compartment is arranged in a coolant circuit of the fuel cell system, and is externally heated, at least at times, by the burner. | 04-15-2010 |
| 20100200317 | Device for Driving a Fuel Cell Vehicle - A vehicle drive system comprises an electrical drive motor and a fuel cell system providing the electrical power. According to the invention, the drive motor and the fuel cell are integrated into a unit and firmly joined together. The fuel cell system may comprise two fuel cells or fuel cell stacks, which are arranged relative to each other so as to form a “V”. Peripheral units for operation of the fuel cell may be arranged in an interior of the V. | 08-12-2010 |
