| 20110269037 | FUEL CELL ASSEMBLY COMPRISING AN IMPROVED CATALYTIC BURNER - There is disclosed a fuel cell assembly comprising at least one horizontally arranged fuel cell stack that has numerous fuel cells, each comprising an anode, a cathode and an electrolyte situated between the anode and the cathode; combustible gas supply means for supplying combustible gas to the anodes of the fuel cells; anode gas withdrawal means for withdrawing the anode exhaust gas from the anodes; cathode gas supply means for supplying cathode gas to the cathodes of the fuel cells; cathode gas withdrawal means for withdrawing the cathode exhaust gas from the fuel cells; and recirculation means for recirculating at least one part of the anode exhaust gas and/or the cathode exhaust gas to cathodes of the fuel cells. The fuel cell assembly according to the invention is characterised in that the recirculation means comprise at least one catalytic burner with catalyst material for burning the remaining combustible gas contained in the anode exhaust gas, said burner being situated at the side of the fuel cell stack. | 11-03-2011 |
| 20110177433 | ANODE FOR A MOLTEN CARBONATE FUEL CELL AND METHOD FOR THE PRODUCTION THEREOF - The disclosure relates to a method for the production of an anode for a molten carbonate fuel cell, wherein a mixture is created, containing at least one base metal and at least one auxiliary agent, and wherein the mixture is applied onto a carrier structure. The disclosure provides that a mixture is used, which contains at least one auxiliary agent in the form of a metal oxide and/or metal hydroxide, and which contains at least one alkali metal compound. The disclosure further relates to an anode that can be produced according to said method. | 07-21-2011 |
| 20110171551 | FUEL CELL ASSEMBLY WITH A MODULAR CONSTRUCTION - There is disclosed a fuel cell assembly comprising: at least one horizontally arranged fuel cell stack that has numerous fuel cells, each comprising an anode, a cathode and an electrolyte situated between the anode and the cathode; combustible gas supply means for supplying combustible gas to the anodes of the fuel cells; anode gas withdrawal means for withdrawing the anode exhaust gas from the anodes; cathode gas supply means for supplying cathode gas to the cathodes of the fuel cells; cathode gas withdrawal means for withdrawing the cathode exhaust gas from the fuel cells; and recirculation means for recirculating at least one part of the anode exhaust gas and/or the cathode exhaust gas to cathodes of the fuel cells.
