HEAT EXCHANGER FOR A HOT FUEL CELL

摘要

The invention relates to a heat exchanger (100) that is intended to operate at the outlet of a hot fuel cell that supplies the exchanger with oxidizing and fuel gases, said heat exchanger comprising: a first oxidizing gas flow circuit (111); a second fuel gas flow circuit (112); a pre-mixing chamber (142) supplied with fuel gases from at least the second circuit and moreover supplied with oxidizing gases; a combustion chamber (140) supplied with the gas mixture from the pre-mixing chamber and moreover supplied with oxidizing gases from the first circuit; and a flue gas flow circuit (114) that receives the flue gases coming from the combustion chamber. The first oxidizing gas flow circuit, the second fuel gas flow circuit, the combustion chamber, and the flue gas flow circuit are submerged in a single heat transfer fluid.
