Description

According to specific application scenarios,Thinkre™ proton  exchange  membrane for  hydrogen  production  from  electrolytic  water  can  be  divided  into:

  • 11x  series  PEM  for  industrial  hydrogen  production;
  • 11x  W  series  PEM  for  civil hydrogen health.
  • R series PEM. Reinforced PEM with better performance for hydrogen production 

Thinkre™ proton  exchange  membrane  for water electrolysis is characterized by high conductvity,  low  gas  permeability  and high   pressure   resistance.

  Measurements taken with membrane conditioned to 23 ℃,50%RH for 24h. 
  Conductivity measurement at 23 ℃,100%RH.
  A base titration procedure measures the equivalents of sulfonic acid group in the polymer resin,thus calculating the acid capacity or equivalent weight of the membrane.
  Water content of membrane conditioned to 23 ℃ and 50%RH(dry weight basis).
  Water uptake from dry membrane to conditioned in water at 100℃ for l hour (dry weight basis).
