PurionX Anion Exchange Membrane - Reinforced
PurionX Anion Exchange Membrane - Reinforced
General Information:
PurionX™ Anion Exchange Membrane 112 and 142 are substrate reinforcement membrane with dry thickness of 50~60 µm and 85~95 µm, excellent ionic conductivity, very high electrochemical stability in alkaline and oxidation environments, and excellent mechanical stability.
Application:
AEM Electrolyzer, AEM Fuel Cell, Electrodialysis, Water Treatment and others.
Advantage:
High performance, scalable, low cost and highly durable AEM to help our customers to achieve high performance and long-term stability in their applications at a reasonable cost.
PurionXTM series AEMs are identified by membrane preparation processes with different suffixes (e.g., 112). Please refer to the product code in case of future queries.
Delivery
The membrane is a semi-transparent film delivered in dry form.
Handling and Storage
Keep membrane package closed/sealed when unused. Store, handle and process the membrane in a clean, dust-free environment. Only use new and sharp blades when cutting the membrane. Gloves should be worn when handling the membrane. The membrane should be handled with care: do not puncture, crease, or scratch the membrane, otherwise leaks may occur. All surfaces in contact with the membrane during handling, inspection, treatment, storage, and installation should be smooth, clean and free of sharp projections.
Long term storage (>12 months) can be done in either dry or wet form under proper operation. Follow the instruction files PurionX™ AEM Dry Storage Instruction’ and ‘PurionX™ AEM Wet Storage Instruction for the manufacturer’s suggested storage operation procedures.
Pretreatment
Follow the instructions below or the instruction file ‘PurionX™ AEM Activation Instruction’ for membrane activation: (1) soak the membrane in 1M KOH in a closed container at a fixed temperature (25℃~80℃) for at least 48 hours, (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.
