The extrusion method is to extrude a perfluorosulfonic acid ion exchange resin into a film by a high-precision screw under a certain temperature and pressure. The casting method is carried out by slowly evaporating and crystallizing the casting solution at a heating temperature lower than the boiling point of the solvent by 10 to 30 ° C. In the solute crystallization process, the casting film disk and the casting liquid therein are in a static closed state. Space, under the radiant heating of the top heating device, the solvent slowly evaporates to reduce the solute concentration slowly, and finally crystallizes into a film. The casting method is to dissolve the raw material in an organic solvent, adjust it into a viscous solution, and cast it on a flat and uniform smooth rotating body, and form a film by baking.
