About

Perfluorosulfonic acid ion exchange membrane N-11 series

Phosphate

Perfluorosulfonic acid ion exchange membrane, also known as perfluorosulfonic acid proton exchange membrane and cation exchange membrane, is a solid polymer electrolyte, a strong acid type ion exchange membrane, with good chemical and thermal stability, low voltage, and low membrane resistance. High conductivity, good hydrophilicity, high water content of the membrane, high mechanical strength, etc., can be used under harsh conditions such as strong acid, strong alkali, strong oxidant medium and high temperature. Due to its own characteristics, perfluorosulfonic acid Proton exchange membranes are not only used as key components of proton exchange membrane fuel cells, but also widely used in the chlor-alkali industry, all-vanadium flow batteries, hydrogen production by water electrolysis, electrochemical synthesis, and gas sensors.

Application:

The PFSA membranes N-11 are non-reinforced films based on PFSA polymer, a perfluorosulfonic acid in the acid (H+) form. Our PFSA membranes perform as a solid polymer electrolyte in fuel cells and other applications in electrochemistry and separation technology for a variety of electrochemical process, especially in the redox flow battery (RFB).
The membranes are located between the cathode and anode and transports protons formed near the catalyst at the hydrogen electrode to the oxygen electrode thereby allowing the current to be drawn from the cell. The membranes show significant improvements in features such as better resistance to chemical attack and longer operating durability in the redox flow battery (RFB).
