20090155653 | FUEL CELL SYSTEM - The invention relates to a fuel cell system comprising a reformer and an afterburner each for reacting at least fuel and an oxidant; and a fuel feeder for supplying the reformer and the afterburner with fuel. It is provided for to particular advantage that at least one flow control valve for controlling the fuel supply is included upstream of at least the reformer or the afterburner. The invention relates furthermore to a motor vehicle having one such fuel cell system. | 06-18-2009 |
20090191434 | FUEL CELL SYSTEM AND METHOD OF INFLUENCING THE HEAT AND TEMPERATURE BUDGET OF A FUEL CELL STACK - The invention relates to a fuel cell system including a fuel cell stack ( | 07-30-2009 |
20090239110 | REFORMER FOR A FUEL CELL SYSTEM - The invention relates to a reformer for a fuel cell system for generating a reformate comprising a plurality of function units for treating the fuel, at least one function unit being adapted to a first type of fuel. In this arrangement the invention is characterized to advantage in that the function unit adapted to the first type of fuel can be releasably coupled to the reformer as a module by means of an interface which is also designed to couple a replacement function unit instead of the function unit adapted to the first type of fuel, the replacement function unit being adapted to a second type of fuel different from the first type of fuel. The invention relates furthermore to a function unit for such a reformer, to a fuel cell system having such a reformer and to a motor vehicle having such a fuel cell system. | 09-24-2009 |
