摘要： PROBLEM TO BE SOLVED: To provide an electrolytic water making method capable of simply washing electrolytic water having washing capacity more excellent than that of electrolytic water made by a conventional electrolizing method. SOLUTION: The anode soln. supplied to a water electrolyzing tank 1 demarcated into two or three chambers by an ion exchange membrane 2 is passed through a cooling jacket 16 before supply to be cooled so as to advance electrolytic reaction at 0-20 V. By performing electrolytic reaction at low temp., a precursor of radicals excellent in washing capacity can be contained in the formed electrolytic water in large quantities and the consumption of electrodes is suppressed to continue stable electrolysis over a long period of time.

摘要： PROBLEM TO BE SOLVED: To surely prevent liquid leakage by installing a first seal material between a circumferential rim part of a cation exchange membrane and an anode chamber frame or between the circumferential rim part of a cation exchange membrane and a cathode chamber frame and installing a second seal material between the anode chamber frame and the cathode chamber frame further outside than the cation exchange membrane. SOLUTION: A first recessed groove 9 is formed into a doughnut shape in a part of the a cathode chamber frame 7 corresponding to the circumferential rim part of an ion exchange membrane 8 and a first seal material 10 made of fluororesin is put in the first recessed groove 9. Further, a second recessed groove 11 is formed into a doughnut shape in a part of a cathode chamber frame 7 to be brought into direct contact with an anode chamber frame in further outside and a second seal material 12 made of rubber is put in the second recessed groove 12. Being pushed to the inner side of the anode chamber frame 4 and the cathode chamber frame 7, both seal materials 10, 12 are deformed and elastically packed in both recessed grooves 9, 11. Consequently, the first seal material 10 prevents liquid leakage for a cathode liquid and even in a case that liquid leakage occurs, the second seal material 12 reliably prevent liquid leakage.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of an inverse current and to suppress the contamination of an electrolyte and the deactivation of an electrode, in an apparatus producing acidic water in the anode chamber of water electrolyzing electrolytic cell and producing alkali water in the cathode chamber thereof, by applying specific voltage and a specific current across an anode and a cath ode even when a power supply is cut off. SOLUTION: In a two-chamber typeelectrolytic cell, ultrapure water having hydrochloric acid dissolved therein supplied from an anode soln. inlet 12 enters an anode chamber from the opening part 13 thereof and comes into contact with an anode 7 to be oxidized to a compd. of high redox potential to be taken out of an anode soln. outlet 14 as acidic water. Ultrapure water supplied from a cathode soln. inlet 16 enters a cathode chamber from the opening part 17 thereof to be taken out of a cathode soln. outlet 18 as alkali water at a time when a power supply is cut off. In this case, a liquid is present in the electrolytic cell, voltage of 1.2V or more and/or a current of 20mA/dm or more are applied across the anode 7 and the cathode 8 to prevent the generation of an inverse current and the contamination of the electrolyte and the deactivation of electrodes caused by the elution of electrode substances are suppressed.

摘要： PROBLEM TO BE SOLVED: To obtain cleaning water with high purity suitable for cleaning electronic apparatus by specifying the materials of an ion exchange membrane, an anode chamber frame, an anode catalyst and a cahotde catalyst. SOLUTION: The main body 1 of an electrolytic cell is composed of an anode chamber gasket 3 and a cathode chamber gasket 4 sandwiching a perfluorocarbon cation exchange membrane 2, an anode chamber wall board 5 and a cathode chamber wall board 6 in which the parts in contact with an electrolyte are made of fluorine resin. The anode face in the cation exchange membrane 2 is provided with a porous anode 7 composed of the powder of platinum group metals or the oxides thereof, and the cathode face is provided with a porous sheet shaped cathode 8 composed of platinum or carbon. An anolyte such as a hydrochloric acid soln. infiltrates into the anode chamber, is brought into contact with the anode 7, is oxidized by a compound having a high oxidation-reduction potential such as hypochlorous acid and is discharged from an anolyte outlet as pickling water. Since the substance small in elution is used as electrode substance, the amt. of impurities intruded into the obtd. washing water can be regulated to zero or a trace.
