PurionX-181 High Performance Anion Exchange Membranes (AEMs)

Applications:

This anion exchange membrane (AEM) is a substrate reinforcement membrane with thickness of 10 to 13 µm, high ionic conductivity, very high electrochemical stability in alkaline and oxidation environments, and mechanical stability. It can be widely used in various fields including AEM Electrolyzer, AEM fuel cell, Electrodialysis, Water Treatment and others.

Delivery:

The membrane is the semi-transparent film delivered in the wet or dry form.

Pretreatment:

If the membrane is delivered in the wet chloride form, the following procedure can be used to make the OH- form: (1) soak the membrane in 1M KOH in a closed container at a fixed temperature (25℃~80℃) for over 12 hrs, (2) then rinse with deionized water copious time until pH neutral. The AEM in OH- form should be used in making the cell quickly or be stored in a sealed container in deionized water to avoid exposure to ambient CO2.

Note: Keep membrane package closed/sealed when unused. Store, handle and process the membrane in a clean, dust-free environment.

Pack Size: 1 pc/pack
