Electrolyzed water production apparatus, and electrolyzed water production method using same

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 an outlet of the electrolysis tank,
• wherein
• the electrolysis tank is formed in a hollow box-like shape and includes a pair of bipolar plates arranged parallel to each other in contact with inner walls of the electrolysis tank facing each other,
• a membrane-electrode assembly is disposed between the bipolar plates parallel to the bipolar plates and includes a solid polymer electrolyte membrane and liquid-permeable electrode catalysts formed in contact with both surfaces of the solid polymer electrolyte membrane, wherein the membrane-electrode assembly partitions an inside of the electrolysis tank to form a first electrolysis chamber and a second electrolysis chamber between the bipolar plates and the membrane-electrode assembly, respectively, and an outlet of the first electrolysis chamber and an inlet of the second electrolysis chamber are connected to each other in an outside of the electrolysis tank in a liquid-tight manner,
• a liquid-permeable power feeder is arranged almost uniformly in each of the first electrolysis chamber and the second electrolysis chamber, wherein the liquid-permeable power feeder electrically connects each of the bipolar plates to each of the electrode catalysts in the membrane-electrode assembly, the power feeder includes a metallic mesh having a three-dimensional structure and having a wire diameter of 10 to 300 μm,
• a thickness of each of the electrode catalysts is 1 to 100 μm, and
• a distance between each of the bipolar plates and each of the electrode catalysts is 1.0 to 3.0 mm.
