Mechanically Reinforced Anion Exchange Membrane (8"x8")

Catalog Number	ACMA00062910
Description	This is a mechanically reinforced Anion Exchange Membrane (AEM) with good hydroxyl anion conductivity, excellent mechanical stability, and high chemical stability in caustic or alkaline and oxidative environments. The ideal alkaline electrolyte concentration for use with this anion exchange membrane is 1M. Yet, the membrane still performs well under conditions with less than 1M or pure water or greater than 1M concentration of electrolyte.
Application	AEM Electrolyzer, AEM fuel cell, Electrodialysis, water treatment and others.
Storage	Long term storage (>12 months) can be done in either dry or wet form with a sealed container. Wet form storage: Soak the membrane in DI water, neutral pH or alkaline aqueous electrolytes (e.g. NaCl, KOH).
Color Form	Clear, semitransparent
Delivery Form	Wet
Dimensional Swelling	<10%
Elongation At Break	20-40% (at 23 deg C, 50% RH)
Feature	High performance, scalable, low cost and highly durable AEM
Ionic Form	Chloride (Cl-)
Notice For Use	The following procedure can be used to make the OH- form: (1) soak the membrane in 1M KOH in a closed container 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. Exposure of the hydroxyl form of the membrane to ambient carbon dioxide will naturally convert the hydroxyl anions in the membrane to carbonate as a result of the chemical reaction between these two species.
Reinforcement	Yes
Tensile Strength	100-120 (at 23 deg C, 50% RH)
Thickness	~50-55 micrometers
Total Exchange Capacity	2.2-2.5 meq/g (Cl- form)
Type	Anion
