A method of electrochemical generation of pure pressurized high pressure hydrogen that comprises, bounding a molten hydroxide or eutectic electrolyte electrochemical pressurizing chamber by a hydrogen-selective anode and a hydrogen-selective otherwise gas impermeable cathode respectively—connected to a D.C. power supply;
- maintaining the pressurizing chamber at a temperature between the melting point of the electrolyte and about 600° C.;
- and wherein, upon passing D.C. current between the anode and cathode, pure hydrogen arriving on the electrolyte bounding with the anode substantially instantaneously reacts with the hydroxyl ions from the electrolyte to form water and electrons and evolves pressurized pure hydrogen gas on the cathode;
- such sibstantially instantaneous reaction at the anode creating a suction effect which effectively pumps pure hydrogen permeating through said anode.
