Compared with other proton exchange membranes, perfluorosulfonic acid proton exchange membranes have the advantages of high mechanical strength, good chemical stability, high conductivity, good thermal stability, strong proton conductivity, etc., and are widely used in fuel cells, electrochemical synthesis, chlor-alkali industry, gas sensors, water electrolysis hydrogen production and other fields. Author: new thinking world industry analysis reference:
The preparation of perfluorosulfonic acid proton exchange membrane includes three methods: solution steel strip casting, molten extrusion casting and solution casting. Melt extrusion casting means that perfluorinated sulfonic acid resin is used as raw material to produce finished products through melting, extrusion casting and other processes. This method does not need to use solvents, and has the advantages of high production efficiency, good quality of finished products, green environmental protection and suitable for continuous production. It is the mainstream preparation method for perfluorinated sulfonic acid proton exchange membrane. The solution casting method has some problems, such as high demand for post-treatment and solvent recovery, so it is not suitable for continuous production.
