Did you know? Teflon proton exchange membrane is the core component of the proton exchange membrane fuel cell. Let’s take a closer look at this material.
PEM, ProtonExchangeMembraneorPolymerElectrolyteMembrane, proton exchange membrane, also known as polymer electrolyte film.
As can be seen from the name, its main function is to transfer protons. In addition, it also needs to isolate the fuel and oxidant to prevent direct chemical reactions caused by penetration.
Teflon proton exchange membrane is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics currently.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
