Description

 

According to specific application  scenarios,  the  company's  proton  exchange  membrane for  hydrogen  production  from  electrolytic  water  can  be  divided  into  11x  series  proton exchange  membrane  for  industrial  hydrogen  production  and  11x  W  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.

  Measurements taken with membrane conditioned to 23 ℃,50%RH. 
  Conductivity measurements at 23 ℃,100%RH.
  A base titration procedure measures the equivalents of sulfonic acid group in the polymer resin,and uses the measurement to calculate 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).
