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 cell and method of electrolysis for producing hydrogen peroxide at a moderate current density while preventing metal deposition on the cathode surface. A feed water from which multivalent metal ions have been removed and in which a salt of a univalent metal, e.g., sodium sulfate, has been dissolved in a given concentration is prepared with an apparatus for removing multivalent metal ions and dissolving a salt in low concentration. The feed water is supplied to an electrolytic cell. Even when electrolysis is continued, almost no deposition of a hydroxide or carbonate occurs on the cathode because multivalent metal ions are not present in the electrolytic solution. Due to the dissolved salt, a sufficient current density is secured to prevent an excessive load from being imposed on the electrodes, etc. Thus, stable production of hydrogen peroxide is possible over a long period of time.
摘要翻译：一种电解槽和电解方法，用于在中等电流密度下生产过氧化氢，同时防止阴极表面上的金属沉积。用一种除去多价金属离子并溶解盐浓度低的装置制备已经除去多价金属离子并且其中以一定浓度的硫酸钠等单价盐溶解的给水的给水。给水供给电解池。即使继续进行电解，因为在电解液中不存在多价金属离子，所以在阴极上几乎不发生氢氧化物或碳酸盐的沉积。由于溶解的盐，确保足够的电流密度以防止对电极等施加过大的负荷。因此，可以长时间稳定地生产过氧化氢。

摘要： An electrode-membrane assembly comprising a pair of electrodes at least one of which is porous, and a thermoplastic resin membrane having a functional group capable of being modified to a free ion exchange group upon hydrolysis, which is interposed between the two electrodes and partly penetrates into the pores of the electrode. In this arrangement, the ion exchange membrane can be mechanically integrated to the anode and cathode to compensate for the insufficiency of mechanical strength of the ion exchange membrane. Thus, an electrode-membrane assembly which can be used in an industrial electrolytic cell or fuel cell is provided.
