摘要： An electrolytic process and apparatus which can operate in a hydrogen reaction chamber at a hydrogen reaction rate corresponding to the increase in the rate of production of hydrogen accompanying the increase in the electrolysis rate and maintain the current efficiency at a very high value with respect to the electrolytic current for producing hydrogen and a process for the production of an electrode for this purpose. An electrolytic process is provided which comprises effecting electrolysis of an electrolytic solution in an electrolytic chamber separated from a reaction chamber by a hydrogen-storing metal member with one surface of the hydrogen-storing metal member as a cathode opposing an anode so that hydrogen thus produced is adsorbed by the hydrogen-storing metal member while allowing hydrogen thus adsorbed and a material to be treated to undergo continuous catalytic reaction in the reaction chamber on the other surface of the hydrogen-storing metal member to cause hydrogenation or reduction reaction by hydrogen thus adsorbed, wherein an electrolytic apparatus having a porous catalyst layer provided on the catalytic reaction surface of the hydrogen-storing metal member is used. The porous catalyst layer is obtained by reducing metal cations in an electroless plating solution by active hydrogen desorbed from a hydrogen-storing metal so that the hydrogen-storing metal is plated with the metal.

摘要： An electrolytic cell for producing acidic water and alkaline water is disclosed. High-purity acidic water and high-purity alkaline water can be produced in a well balanced proportion from ultrapure water which is supplied in the minimum amount necessary for producing the desired acidic and alkaline waters using the minimum amount of electricity. The electrolytic cell includes an electrolytic acidic-water production unit 3 comprising an anode chamber 6 and an auxiliary cathode chamber 7 separated therefrom by a first ion-exchange membrane 5, and an electrolytic alkaline-water production unit 4 comprising a cathode chamber 10 and an auxiliary anode chamber 9 separated therefrom by a second ion-exchange membrane 8. Separately controllable power supplies are also provided for supplying power to each of the two units. The supply amount of pure water and the amount of electricity used can be fixed according to the desired amounts of acidic and alkaline waters. Thus, wasteful use of ultrapure water and electric power can be avoided.

摘要： A method of electrolytically producing acid water using an electrolytic cell partitioned by a cation-exchange membrane into an anode chamber and a cathode chamber. Chloride ion which generates hypochlorous acid by anodic oxidation is supplied to the cathode chamber without directly supplying chloride ion to the anode chamber. Part of the chloride ion permeates from the cathode chamber into the anode chamber through the cation-exchange membrane. The chloride ion which permeates through the cation-exchange membrane is present at the surface of an anode closely adhering to the cation-exchange membrane in the anode chamber or only in the vicinity of the anode, and is efficiently anodically oxidized to form hypochlorite ion. Also disclosed is an electrolytic cell for carrying out the method of electrolytically producing acid water.

摘要： A gas-diffusion cathode disposed in contact with an ion-exchange membrane partitioning an electrolytic cell into an anode chamber and a cathode chamber, wherein at least one guide piece is disposed in the gas-diffusion cathode and a salt water electrolytic cell using the above-described gas-diffusion cathode. By using the above-described gas-diffusion cathode for salt water electrolysis, an aqueous caustic alkali solution formed descending in the direction of gravity in the cathode changes direction of movement by contact with a guide piece, whereby the decreased electrode performance resulting from the hindrance of the supply of raw material gas and the discharge of the gas formed caused by the retention of the descending caustic alkali solution is prevented and a large-sized electrolytic cell can be used without problems generally encountered in conventional electrolytic systems.

摘要： Electrolysis is carried out while supplying an aqueous sodium chloride solution having a weak acidic property to the anode chamber of a water electrolytic cell. The electrolytic cell is partitioned with a cation-exchange membrane into an anode chamber and a cathode chamber. Furthermore, because the pH of the anolyte is sufficiently reduced due to the acid content and pH of the liquid supplied to the anode chamber from the start of electrolysis, which is different from a conventional electrolytic method, the electrolysis of the present invention may be carried out for a time needed to obtain a sufficiently high oxidation reduction potential. Thus, acid water almost the same as that obtained in a conventional method is obtained in the present invention by consuming about {fraction (1/10)} the electric power that is used in a conventional method.

摘要： An apparatus for producing electrolytic water in which the yielded electrolytic water does not suffer quality deterioration caused by chemical species, e.g., hydrogen ions, moving to the counter-electrode chamber. A diaphragm 4 of a two-chamber type electrolytic cell comprises two or more ion-exchange membranes 3, and a noble-metal layer 2 or another layer may be formed in the diaphragm. Use of the ion-exchange membranes produces an enhanced physical screening effect, while formation of the noble-metal layer produces catalytic effect to decompose chemical species. Both the ion-exchange membranes and the anode-metal layer are effective in diminishing the movement of chemical species to the counter-electrode chamber.

摘要： An electrolytic cell for the production of acid water which performs simple operation to produce acid water without complicated control over the concentration of hydrochloric acid to be added or precipitation of alkaline earth metal salts, which are disadvantages of the prior art electrolysis for the production of acid water. An electrolytic cell for the production of acid water, which comprises a power supply for applying a voltage across an anode chamber and a cathode chamber partitioned by an ion-exchange membrane. The anode in the anode chamber is disposed in close contact with the ion-exchange membrane. The electrolytic cell further comprises means for supplying an aqueous solution of hydrochloric acid and water to the cathode chamber and the anode chamber, respectively. Hydrochloric acid is not directly added to the anode chamber but indirectly added to the anode chamber by diffusing through the ion-exchange membrane. In this manner, hydrochloric acid is uniformly dispersed into the anode chamber by diffusing through the ion-exchange membrane. Thus, the need for controlling concentration is eliminated. Furthermore, because both the catholyte and anolyte are kept acidic, no precipitation of metal salts occurs.
