The graphene perfluorinated sulfonic acid cation exchange membrane has added a new type of compound fluorine resin and graphene formula with good vanadium resistance during the casting process. After testing, the use of the new additive mix ratio reduced the penetration of vanadium by more than 80%.
The graphene perfluorinated sulfonic acid cation exchange membrane uses 1000 equivalents of high-quality perfluorinated sulfonic acid ion exchange resin as raw material, and has stable performance, and is doped with an optimal ratio of vanadium-barrier fluorine resin, thereby ensuring high conductivity and low vanadium permeability.
