摘要： A problem of the present invention is to provide a solid polymer membrane electrode capable of obtaining electrolyzed hydrogen water in which an increase of the pH is suppressed and which has a sufficient dissolved-hydrogen amount. The present invention is concerned with a solid polymer membrane electrode for generating electrolyzed water, wherein the solid polymer membrane electrode includes a solid polymer membrane and catalyst layers containing a platinum group metal and provided on the back and front of the solid polymer membrane; and the solid polymer membrane is a hydrocarbon-based cation exchange membrane and has an ion exchange capacity per unit area of 0.002 mmol/cm2 or more and 0.030 mmol/cm2 or less.

摘要： An electrolyzed water generating device 1 has an electrolysis chamber 40, a first feeding body 41 and a second feeding body 41 to which a DC voltage is applied, a diaphragm 43 disposed between the first feeding body 41 and the second feeding body 42 to divide the electrolysis chamber 40 into a first-polar chamber 40a and a second-polar chamber 40b, a control unit 5 for switching a polarity of the first feeding body 41 to an anode or a cathode and a polarity of the second feeding body 42 to a cathode or an anode, a flow rate sensor 22 detecting an amount of flowing water into the electrolysis chamber 40 on the cathode side per unit time, and a current detecting means 44 detecting a DC current supplied to the first feeding body 41 and the second feeding body 42. The surfaces of the first feeding body 41 and the second feeding body 42 are formed of a hydrogen storage metal. The control unit 5 calculates a concentration of hydrogen storage metal colloid based on the DC current and an integrated value of the amount of flowing water after switching the polarities.
