TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Process: The process of the hydrolysis of the reactive metal and the process of the reduction of the reactive metal from the hydroxide of the reactive metal are carried out in the same device in the form of an electrolyzer, having the tank with a cathode and anode and diaphragm(s) between the cathode and the anode. In the process of the hydrolysis of the reactive metal, the cathode and the anode are electrically connected to a service load through a switch (17), water is fed to the anode (cathode) so that the evolution of hydrogen occurs at the anode (cathode), and water is fed onto the diaphragm so that the evolution of hydrogen occurs at the diaphragm, where the diaphragm is electrically connected to the cathode and made in the form a mesh wire. In the process of the electrolytic reduction of the reactive metal, the hydroxide of the reactive metal is heated up to 180-220 degrees Celsius. The reduced reactive metal and water liberated in the process of the electrolytic reduction of the reactive metal are re-used in the process of the hydrolysis of the reactive metal.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Components: The lower section of the porous diaphragm has through channels. The device comprises an electrical heater (10) for heating the cathode and the hydroxide of the reactive metal. The device comprises a hydrogen pressure transducer, device for an adjustable water supply to the tank. The device for an adjustable water supply to the tank has a negative feedback with the hydrogen pressure transducer. The hydrogen extractor is connected to a hydrogen accumulation tank connected to a hydrogen consumer. The oxygen and water vapor extractor has a water vapor condenser (14).    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: An alkali metal or alkaline-earth metal is used as the reactive metal. Lithium is used as the reactive metal. The reactive metal such as lead, tin, bismuth, or cadmium is used as the additive. The tank is made of non-conducting material.    TECHNOLOGY FOCUS - METALLURGY - Preferred Composition: An alloy of reactive metals comprising 20-25 wt.% lead, 10.5-12.5 wt.% tin, 45-50 wt.% bismuth, and cadmium being balance, is used as the additive. The non-consumable component of the cathode contains the alloy of reactive metals.    TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Materials: The porous diaphragm is made of a ceramic material.
