Abstract
A heat exchanger for operating at an outlet of a hot fuel cell feeding the heat exchanger with oxidizer gas and with fuel gas, the heat exchanger including: a first flow circuit for oxidizer gas; a second flow circuit for fuel gas; a pre-mixer chamber fed both with oxidizer gas and with fuel gas from at least the second circuit; a combustion chamber fed with the gaseous mixture from the pre-mixer chamber and with oxidizer gas from the first circuit; and a flow circuit for flue gas, receiving the flue gas coming from the combustion chamber. The first flow circuit for oxidizer gas, the second flow circuit for fuel gas, the combustion chamber, and the flow circuit for flue gas are immersed in a common cooling fluid.
