About
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.
PEM proton membrane water electrolysis hydrogen production selects perfluorosulfonic acid proton exchange membrane with good chemical stability, proton conductivity and gas separation as solid electrolyte, which can effectively prevent electron transfer and improve the safety of electrolyzer. The main components of the PEM water electrolyzer are proton exchange membrane, cathode and anode catalyst layers, cathode and anode gas diffusion layers, cathode and anode end plates, etc. from inside to outside. Among them, the diffusion layer, catalytic layer and proton exchange membrane constitute the membrane electrode, which is the main place for material transport and electrochemical reaction in the entire water electrolyzer. The characteristics and structure of the membrane electrode directly affect the performance and life of the PEM water electrolyzer.

Application:
The PFSA membranes for hydrogen production from water electrolysis 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 electrolysis industry and other applications in electrochemistry and separation technology for a variety of electrochemical process.
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 electrolyte.
