The method for producing electrolyzed water includes the step of applying a voltage to electrodes disposed in an electrolytic cell containing therein pure water including electrolyte therein. A strength of an electric field generated by applying a voltage to the electrodes is controlled to be variable by means of various techniques. The method makes it possible to produce electrolyzed water with a smaller amount of energy than prior methods.

Electrolytic method for preventing fouling of sea water-immersed structures by marine life

PURPOSE:To prevent the nonuniform distribution of an electric current resulting from the resistance increase due to the consumption of a coating film and the variance in the film thickness and to exert a high-performance antifouling effect by setting a power source for applying a DC current in the direction of an electric conductor from an inner conductive coating film through an outer conductive coating film CONSTITUTION:A DC current is allow to flow in the direction of a cathode 6 in seawater 2 from the inner conductive coating film 4 through the outer conductive coating film 5, hence the surface of the outer film 5 is covered with a dense chlorine film, and the deposition of marine organisms on the surface is prevented The DC current in this case is supplied in the thickness direction of the outer film 5 through the base current of the inner film 4 having a low electric resistance from an electric terminal 4a provided to the inner film 4 Accordingly, even when the inner film 4 is consumed, the current density is not concentrated close to the terminal 4a, a stabilized uniform current density distribution can be maintained over a long period, and hence a high-performance antifouling effect can be exerted with low power consumption
