Abrégé
The invention concerns a device (10) generating hydrogen from a liquid or gaseous hydrocarbon, in particular diesel fuel, oxygen and water. It comprises: a reaction chamber (12) wherein the reactive fluids are introduced to perform a reforming reaction which produces hydrogen and carbon oxides from reagents, said reaction being carried out at high temperature; - a first substantially cylindrical zone (14) surrounding the reaction chamber and wherein circulates a mixture of water vapour and hydrocarbon to be introduced into the reaction chamber, excluding the reaction products, said zone being separated from the reaction chamber so as to recover, at least partly, the heat lost by the reaction chamber, in order to preheat the mixture circulating in the first zone, the reagent(s) being in direct contact with the walls (30, 32) of said first zone to produce heat exchanges; - a substantially cylindrical second zone (16) surrounding the first zone and wherein circulates water to be vaporized, the water being in direct contact with the walls (18, 34) of said second zone, the separation (34) between the first zone and the second zone being such that the water circulating in the second zone recovers the heat of the first zone to preheat the water; and means for mixing the water of the second zone with the hydrocarbon prior to introducing the mixture in water vapour form into the first zone.

Abrégé
Process for supplying gaseous oxygen to the cathode (3) of a battery (1) of the proton-exchange diaphragm type, according to which a gas, rich in oxygen such as pure oxygen, is mixed with the gas effluent from the cathode so as to create a supply mixture for the cathode containing more than 60% of neutral gas.
