摘要： A liquid-permeable gas-diffusion cathode adapted for caustic soda electrolysis in contact with an ion-exchange membrane partitioning an electrolytic cell into an anode chamber and a cathode gas chamber. Plural horizontal concave grooves and/or convex portions are provided in an interval with one another on the surface of the gas-diffusion cathode facing the gas chamber. Plural vertical concave grooves may also be provided in an interval on the surface of the cathode crossing the horizontal grooves and/or convex portions. Aqueous caustic soda solution thus formed flows downward along the grooves, etc., without covering other portions of the cathode surface, and is easily released therefrom without clogging perforations in the gas-diffusion layer of the cathode.

摘要： A method is disclosed, which is capable of subjecting microorganisms to sterilizing or bacteriostatic treatment with good efficiency as compared with the conventional sterilizing or bacteriostatic method using a noble metal electrode. Microorganism-containing water to be treated is electrochemically treated using an anode having conductive diamond to bring the microorganism into contact with the anode, thereby undergoing sterilization. Since the conductive diamond has a high oxidation potential as compared with other electrode substances, direct oxidation reaction due to contact between a microorganism in water to be treated, such as Legionella bacteria, and the anode surface occurs strongly as compared with other electrodes, thereby enabling effective sterilization. The conductive diamond has a high ability to generate ozone and has an excellent formation efficiency with respect to the generation of hydrogen peroxide and radicals. Accordingly, an indirect sterilizing effect can also be expected.

摘要： A functional water containing a fluorine-containing component obtained by electrolyzing an aqueous solution containing fluoride ion using electrodes having conductive diamonds, a method of producing the same, and a method and an apparatus of rinsing electronic parts using the functional water as a rinsing water. The fluorine-containing component produced by electrolyzing the fluoride ion using the conductive diamond, has stronger rinsing effect than that of a fluorine-containing component obtained by electrolyzing the fluoride ion itself before electrolysis or the fluoride ion using other electrodes. Therefore, an amount of hydrofluoric acid used can greatly be decreased.

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.
