Document Type and Number:
WIPO Patent Application WO/2016/186085
Kind Code:
A1
Abstract:
This ion exchange membrane has: a layer A that includes a fluorine-containing polymer that has a sulfonic acid group; and a layer B that includes a fluorine-containing polymer that has a carboxylic acid group. The value of the ion cluster diameter distribution M, as represented by formula (B), for the layer B is greater than 10. (In formula (B), M represents ion cluster diameter distribution, a0 represents average ion cluster radius, and σ represents ion cluster radius standard deviation.)
