About this item Core Compatibility for Electrochemical Applications: the AEM is designed for use in advanced electrochemical systems, such as alkaline water electrolysis, fuel cells (especially alkaline fuel cells), electrodialysis (seawater desalination, acid/base recovery), and CO₂ reduction. It offers broad pH stability, making it highly compatible with harsh chemical environments Four Options for Specific Needs: the AEM offers four standard models to meet diverse needs Model Thickness Key Feature Recommended Applications SL-PK-130 130 μm High mechanical strength High-pressure processes such as water electrolysis and CO₂ reduction SL-PK-75 75 μm Low resistance & high durability Electrodialysis desalination, acid recovery SL-50 50 μm Extremely low area resistance, protective backing Weak alkaline electrolytes in electrodialysis and fuel cells SL-20 20 μm Ultra-thin, lowest resistance Fundamental electrochemical research, microdevice development Long-Term Stability & High Performance: all models exhibit low area resistance, high ion selectivity, and exceptional chemical stability across a wide pH range (0-14), ensuring reliability and consistency in demanding Convenient Delivery & Immediate Use: supplied in dry, flat, brown polymer film form, available in sizes ranging from 3x3 cm to 20x20 cm. The SL-50 and SL-20 models come with a PET protective backing, which should be carefully removed before use for optimal performance Custom Support & Cutting Services: comprehensive support for R&D and prototype development is available. We offer standard sizes in stock and can provide custom cutting services for specific research or pilot-scale needs. Please consult us for custom options or contact customer service for more information Anion Exchange Membrane Pre-treatment Instructions: the membranes are supplied in a dry state but may contain traces of residual water, additives, and solvents. These can be removed by soaking in deionized water. If additional cleaning is required, rinse the membrane with the application-specific solution or deionized water according to your process needs. Depending on the application and cell design, assembly can be performed either dry (without pre-treatment) or wet. Pre-treatment for Wet Assembly: Place the membrane sample between stable mesh/spacers in a NaCl solution (to avoid curling), e.g., in 0.5M NaCl solution at T=25°C for 72 hours, replacing the solution multiple times. Do not let the membrane dry out, as micro-cracks may develop during shrinkage. The membrane will swell and shrink depending on its water/electrolyte content.Alternatively, pre-soaking can be performed using the reaction solution intended for your specific application.
