Title:
ELECTROLYZED WATER PRODUCTION APPARATUS, AND ELECTROLYZED WATER PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/195708
Kind Code:
A1
Abstract:
The present invention provides an electrolyzed water production apparatus comprising an electrolysis raw water supplying means, an electrolysis tank connected to the electrolysis raw water supplying means, and an activated carbon filter connected to the outlet side of the electrolysis tank. The electrolyzed water production apparatus is characterized in that: the electrolysis tank is formed in a hollow box-like shape and is equipped with a pair of bipolar plates, in which the bipolar plates are respectively adhered onto inner walls of the electrolysis tank which face each other, and are arranged in parallel with each other; a membrane-electrode assembly, which comprises a solid polymer electrolyte membrane and liquid-permeable electrode catalysts respectively formed in contact with both surfaces of the solid polymer electrolyte membrane, is provided between the bipolar plates in parallel with the bipolar plates, so that the inside of the electrolysis tank is partitioned to form a first electrolysis chamber and a second electrolysis chamber respectively between the bipolar plates and the membrane-electrode assembly; the outlet side of the first electrolysis chamber and the inlet side of the second electrolysis chamber are connected to each other in the outside of the electrolysis tank in a liquid-tight manner; a liquid-permeable power feeder is arranged approximately uniformly in each of the first electrolysis chamber and the second electrolysis chamber, electrically connects the bipolar plates to the electrode catalysts in the membrane-electrode assembly, respectively, and comprises a metallic mesh having a three-dimensional structure and having a wire diameter of 10 to 300 (μm); the thickness of each of the electrode catalysts is 1 to 100 (μm); and the distance between each of the bipolar plates and each of the electrode catalysts is 1.0 to 3.0 (mm).
