Polytetrafluoroethylene proton membrane is an indispensable core component material of fuel cells. It plays a vital role in the overall performance and service life of fuel cells. It plays an important role, let us take a look at it below.
Perfluorosulfonic acid proton exchange membrane is currently mainly used on the market. In terms of production technology, the current mainstream perfluorosulfonic acid PEM The most commonly used processing methods are hot melt extrusion film forming method and solution casting film forming method. Although perfluorosulfonate PEM is currently the most widely used, it still has the disadvantages of higher cost, poor dimensional stability, and increased temperature that reduces proton conductivity.
Polytetrafluoroethylene proton membrane is an excellent polymer material that is resistant to high temperatures, corrosion, and dielectric properties. It has excellent, stable chemical properties and good mechanical properties, so this material is widely used in all aspects of engineering, military, and life. However, polytetrafluoroethylene polymer is non-polar and its surface free energy is very low, which makes its surface wetting and hydrophilic properties very poor, which affects its wide application in actual production.
The polytetrafluoroethylene proton membrane produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. It has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; it uses production testing instruments imported from the United States to test the quality of PTFE film, and has passed international SGS testing and certification, as well as ISI testing and certification.
