Pronton exchange membrane for PEMWE
According to specific application scenarios,Thinkru proton
exchange membrane for hydrogen production from electrolytic watercan be divided into 11x series proton exchange membrane for industrial hydrogen production and 1lxW series proton exchange
membrane for hydrogen health.Nepem proton exchange membrane
for electrolytic water has the characteristics of high conductvity, low gas permeabllity and high pressure resistance.
Special membrane for electrolyzed water: T-N-115
Special film for hydrogen absorption machine and hydrogen-rich water cup: T-N-115W
The difference between T-N-115/T-N115W is that T-115W has no odor, and the processing formula is different.
T-N-11x Series(T-N-115/T-N-117):
The T-N-11x series membrane is a perfluorinated sulfonate resin homogeneous membrane, that has excellent heat resistance, mechanical properties, electrochemical properties Chemical properties and chemical stability, can be used in strong acid, strong alkali, strong oxidation, and other harsh conditions, and is widely used in industrial PEM electrolytic hydrogen production and other fields.
T-N-11X W Serie (T-N-115W/T-N-116W/T-N-117W):
Compared with T-N-11X series membranes, W-series membranes optimize the formulation and treatment process of membrane preparation liquid and have lower solvent residue, which is widely used in the field of hydrogen health.

2.Conductivity measurements a23°C,100%RH.
3.A base titration procedure measures the equivalents of sulfonic acid group in the polymer resin,and uses the measurementto calculate
the acid capacity orequivalent weight ofthe membrane.
4.Dissolved hydrogen concentration was performed using a hydrogen-rich watertest pen (ENH-1000 Portable Dissolved hydrogen Meter),
which was based on the principle of oxidation reduction potential in the solution to calculate the dissolved hydrogen concentration.
