Abstract

See full text

A cation exchange membrane includes: a membrane body containing a fluorine-based polymer having an ion-exchange group; and two or more reinforcing core materials arranged approximately in parallel within the membrane body. The membrane body is provided with two or more elution holes formed between the reinforcing core materials adjacent to each other. A distance between the reinforcing core materials adjacent to each other is represented by a, a distance between the reinforcing core materials and the elution holes adjacent to each other is represented by b, a distance between the elution holes adjacent to each other is represented by c, and the number of the elution holes formed between the reinforcing core materials adjacent to each other is represented by n. The relationship represented by the following expression (1) or expression (2) are satisfied:

description='In-line Formulae' end='lead'b>a/(n+1)  (1);description='In-line Formulae' end='tail'

description='In-line Formulae' end='lead'c>a/(n+1)  (2).description='In-line Formulae' end='tail'
