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 |
20090263685 | METHOD AND SYSTEM FOR FEEDBACK CONTROLLING/CONTROLLING A TOTAL AIR FUEL RATIO OF A REFORMER - The invention relates to a method for closed/open loop control of a total lambda value of a reformer ( | 10-22-2009 |
20090280365 | FUEL CELL SYSTEM AND METHOD OF STARTING A FUEL CELL SYSTEM - The invention relates to a method of starting up a fuel cell system comprising a reformer ( | 11-12-2009 |
20100047632 | TEST BENCH AND TESTING METHOD FOR A FUEL CELL STACK - The invention relates to a test stand for a fuel cell stack comprising an insulating device for thermally insulating the fuel cell stack, a media supply device for supplying a gaseous fuel and an oxidising agent to the fuel cell stack and an electronic control device for controlling and/or regulating as well as for monitoring a test method. The invention further relates to a test method for a fuel cell stack. | 02-25-2010 |
20100062290 | METHOD FOR TESTING THE IMPERMEABILITY OF A FUEL CELL STACK - The invention relates to a method for testing the leak-tightness of a fuel cell stack comprising the steps of operating the fuel cell stack using defined gas supply rates, a defined modification of at least one gas supply rate, detecting at least one cell or cell group voltage and analysing the variation in time of the at least one cell or cell group voltage. | 03-11-2010 |
20110311892 | FUEL CELL SYSTEM WITH REFORMER AND REHEATER - The Intention relates to a fuel cell system comprising a reformer with a burner unit for reacting fuel with oxidant in an exothermic oxidation reaction to form a product gas which downstream of the burner unit is mixable with additional fuel, the resulting gas mixture being reformable in the reformer into a reformate; a fuel cell stack for receiving a supply of the reformate; and an afterburner for receiving a supply of the substances reacted in the fuel cell stack, with a burner unit for reacting fuel with oxidant in an exothermic oxidation reaction. In accordance with the invention it is provided for the burner unit of the reformer is engineered identical to the burner unit of the afterburner. In addition, the invention relates to a motor vehicle comprising one such fuel cell system. | 12-22-2011 |
