Thinkre™ PEM for Vanadium Flow Battery(VFB)

NEPEM Proton exchange membrane for vanadium flow battery/VFB

Category：

Thinkre™ Perfluorosulfonic PEM

Description

The strength,moisture retention and vanadium resistance of Thinkre™ proton exchange membrane(ion exchange membrane)are improved by adding special materials in the production process of tape casting.

◮  Measurements taken with membrane conditioned to 23° ℃,50% RH for 24h.
◮  Conductivity measurements at 23 ℃,100% RH.
◮  A base titration procedure measures the equivalents of sulfonic acid group in the 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 lh(dry weight basis).
