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.

Abstract: An electrolytic apparatus that can be immersed in a saline solution, includes at least one electrolytic cell having a body (1) and a cover (2) made of an insulating material; this body contains two power supply electrodes formed by a plate (3) and a rod (3a) manufactured in a single piece. The outer surfaces of the body have snap-coupling formations for assembling a plurality of cells.
