MEMBRANE-ELECTRODE ASSEMBLY, ELECTROLYTIC CELL USING THE SAME, METHOD AND APPARATUS FOR PRODUCING OZONE WATER, METHOD FOR DISINFECTION AND METHOD FOR WASTEWATER OR WASTE FLUID TREATMENT

摘要

This invention is to provide a membrane-electrode assembly, an electrolytic cell using the same, a method and an apparatus for producing ozone water, a method for disinfection and a method for wastewater or waste fluid treatment, by using which allow electrolysis reaction products or decomposition products to be produced at a high efficiency, channel pressure drop to be minimized, and the apparatus to be designed compact in size without sacrificing the production capacity. This invention relates to a membrane-electrode assembly, comprising an anode having a plurality of through-holes of 0.1 mm or more in diameter; a cathode having a plurality of through-holes of 0.1 mm or more in diameter at the same sites as in the anode; and a solid polymer electrolyte membrane coated on one face or the entire face of at least one of the anode and the cathode with the through-holes being maintained, wherein the anode, the solid polymer electrolyte membrane and the cathode are tightly adhered.
