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.

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