Abstract: The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.

Abstract: The invention concerns a system for energy and environmental optimisation of a facility comprising at least one combustion apparatus (1) with a burner (3). The system comprises an electrolyser (2) and an injection system (4) connected to at least one fuel (3a) and/or oxidant (3b) inlet of the burner (3). The injection system is capable of injecting, at such an inlet, gases from the electrolyser (2) and/or a mixture of these gases and a combustible fluid and/or an oxidising fluid. The electrolyser (2) and/or the injection system (2) are controlled on the basis of at least one piece of information originating from the combustion apparatus (1) and/or sensors (6x) of the installation. The electrolyser can comprise a heat exchanger (2a) for cooling the device and/or preheating the water (EP) that is intended to then be heated (EC) by the combustion apparatus (1).

Abstract: An electrode is provided that is suitable for use with the electrolysis of water in a liquid electrolyte medium, the electrode formulated by the following formulation method: a) dissolving, in a volatile solvent or a mixture of volatile solvents, at least one ion-conducting polymer binder that allows, in the solid state, the diffusion of the gases formed during electrolysis; b) adding, to the solution obtained in step a), at least one electrocatalytic material in the form of divided powder, in order to obtain a mixture; and c) depositing the mixture obtained in step b) on a metallic or metallic-type conductive support or collector, said support or said collector being openwork and chemically stable in an aqueous medium, steps a) and b) being able to be implemented simultaneously, successively or to be reversed.
