FIELD: chemistry.SUBSTANCE: group of inventions relates to cation-exchange membrane, electrolyser with cation-exchange membrane and method of membrane manufacturing. Cation-exchange membrane includes membrane body, which contains fluoric polymer, which has ion-exchange group; and two or more reinforcing filling agents, located parallel inside membrane body. Membrane body is provided with two or more holes for elution, formed between adjacent to each other reinforcing filling agents. If the distance between adjacent to each other reinforcing filling agents is presented as distance a, the distance between reinforcing filling agents and holes of elution, adjacent to each other, is presented as b, the distance between holed for elution, adjacent to each other is presented as c, and the number of holes for elution, formed between adjacent to each other reinforcing filling agents, is presented as n, then a, b, c and n satisfy the ratio, presented by expression (1) or expression (2): b>a/(n+1) (1), c>a/(n+1) (2), where n constitutes from 2 to 4.EFFECT: group of inventions ensures obtaining membrane, possessing mechanical bending strength and ensuring stable electrolytic characteristics for a long-term period.12 cl, 10 dwg, 4 tbl, 9 ex |
