As a key component of fuel cells and electrolyzers, proton exchange membranes need to have good proton conductivity and low proton conductivity. The current mainstream proton exchange membrane solution is perfluorosulfonic acid proton The exchange membrane is composed of a fluorocarbon main chain and an ether branch chain with a sulfonic acid group. The advantages of the perfluorosulfonic acid proton membrane are high mechanical strength, good chemical stability, high electrical conductivity, high current density at low temperatures, and low proton conduction resistance; but the disadvantage is that the proton conductivity becomes worse as the temperature rises, and chemical degradation is prone to occur , the cost is also higher.
PTFE proton membrane is a high-performance polymer film with Excellent chemical resistance, high resistance, low surface energy, fluoride ion conductivity and other characteristics. It is often used in fuel cells, water electrolysis to produce hydrogen, hydrogen storage and other electrochemical fields.
In fuel cells, compared with traditional acid electrolyte fuel cells, the use of PTFE proton membrane can greatly reduce the energy consumption of fuel cells. Hydrogen leakage rate and system internal humidity improve battery stability and life.
In addition, it can also be used to electrolyze water to produce hydrogen. Hydrogen production through electrolysis of water is a sustainable method of hydrogen production. By electrolyzing water into hydrogen and oxygen, electrical energy from the energy source can be used to drive the reaction process. Using this membrane as the separation membrane of an electrolytic cell can achieve a good electrolysis process and solve problems such as electrode growth and membrane impedance in traditional electrolysis methods. It can also reduce energy consumption and improve hydrogen purity.
The PTFE proton membrane produced is the core material of the fuel cell. It has the advantages of high tensile strength, high electrical conductivity, and good chemical properties. After composite reinforcement with PTFE reinforced mesh, the strength is greatly improved and the swelling rate is lower. Interested parties are welcome to enter the store and consult us.
