摘要：
A cation exchange membrane manufacturing method in which a film of a blend which consists of a perfluoro carbon polymer having a group transformable into a sulfonic acid group and a perfluoro carbon polymer having a group transformable into a carboxylic acid group or a film of a copolymer which consists of a perfluoro carbon monomer having a group transformable into a sulfonic acid group and a perfluoro carbon monomer having a group transformable into a carboxylic acid group and another film of a perfluoro carbon polymer having a group transformable into a carboxylic acid group are joined together. Following that, the group transformable into a carboxylic acid group and the group transformable into a sulfonic acid group are transformed respectively into the carboxylic acid group and the sulfonic acid group.
