FUEL CELL ASSEMBLY WITH IMPROVED GAS RECIRCULATION

摘要

The invention relates to 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 comprises at least one collection line (59) situated on one long side of the fuel cell stack for collecting the exhaust gases to be recirculated, said line opening into an inlet of a delivery unit (20, 22) which is situated on the end face of the fuel cell stack and which has an outlet (63) that communicates with the cathode gas supply means.
