Thinkre™ PFSA PEM

Description

Thinkre ion exchange membrane represents the heart of flow battery, PEM water electrolyzer and hydrogen fuel cell. Alongside our experts, Thinkre group has already opened up the whole industrial chain from TFE to PFSA resins to PEMs and achieved industrialization with 3 production bases.

The strength, durability, moisture retention and vanadium resistance of Thinkre ion exchange membranes for Redox Flow Battery (RFB) are improved by introducing special materials during the tape casting process of membrane preparation. In this way Thinkre PEM can provide worldwide leading-edge solution for RFB.

In addition, the new generation of Thinkre PEMs for flow batteries adopts self-developed perfluorosulfonic acid resin, which further improves the coulombic efficiency and energy efficiency in the application of flow energy storage batteries.
