Device for the production on-demand of hydrogen by electrolysis of aqueous solutions from dry cathode

This invention relates to a device for the electrolytic production of hydrogen which can operate discontinuously or associated to strong power fluctuations and provide dry pressurized directly hydrogen, with high purity. The device for the electrolytic production of hydrogen from an alkaline aqueous solution, starting from dry cathode, comprises two half-cell, anodic and cathodic, separated by an anionic exchange membrane whose surface in contact with the cathodic half-cell is a membrane-electrode assembly (MEA), and the alkaline solution is present only in the anodic half-cell.
