Abstract
Official abstract text for this publication.
The invention relates to a fuel cell assembly having a plurality of fuel cells amalgamated electrically and mechanically in a fuel cell stack, further including a residual gas treatment device for hydrogen-containing and oxygen-containing residual gases of the fuel cells, wherein the residual gas treatment device includes a recombination fuel cell with catalyst and membrane that is led via a power circuit separate from the fuel cells, and to a method for treating hydrogen-containing and oxygen-containing residual gases from fuel cells.
First claim
Opening claim text (preview).
1 . A fuel cell assembly comprising a plurality of fuel cells amalgamated electrically and mechanically in a fuel cell stack, further comprising a residual gas treatment device for hydrogen-containing and oxygen-containing residual gases of the fuel cells, characterized in that the residual gas treatment device comprises a recombination fuel cell with catalyst and membrane that is led via a power circuit separate from the fuel cells. 2 . The fuel cell assembly as claimed in claim 1 , wherein the recombination fuel cell is directly downstream of the fuel cells in the fuel cell stack. 3 . The fuel cell assembly as claimed in claim 1 , wherein the recombination fuel cell is downstream of the fuel cells outside the fuel cell stack. 4 . The fuel cell assembly as claimed in claim 1 , wherein a measuring device for voltage and/or current is integrated into the recombination fuel cell or connected to the recombination fuel cell. 5 . The fuel cell assembly as claimed in claim 1 , wherein a metal-sheet recombination cell is arranged between the fuel cells and the recombination fuel cell, the membrane of the recombination fuel cell being replaced in the metal-sheet recombination cell by a metal sheet. 6 . A method for treating hydrogen-containing and oxygen-containing residual gases from fuel cells, in which the residual gases from fuel cells amalgamated electrically and mechanically in a fuel cell stack are supplied to a recombination fuel cell which is led via a power circuit separate from the fuel cells. 7 . The method as claimed in claim 6 , wherein the residual gases within the fuel cell stack are supplied to the recombination fuel cell. 8 . The method as claimed in claim 6 , wherein the residual gases are led out of the fuel cell stack and supplied to the recombination fuel cell. 9 . The method as claimed in claim 6 , wherein voltage and/or current strength of the recombination fuel cell is measured. 10 . The method as claimed in claim 6 , wherein residual gases flow first through a metal-sheet recombination cell in which instead of a membrane, as in the recombination fuel cell, a metal sheet is arranged, before they are led into the recombination fuel cell.
