Description

The Aquivion(R) E87-05S Membrane Sheet, Contains Cf3 Polymer Chain Ends As Stabilizer, Pfsa Eq. Wt. 870 G/Mole So3H, L X W X Thickness 18 Cm X 18 Cm X 50 Mum is a high-performance perfluorosulfonic acid (PFSA) ionomer membrane engineered for demanding electrochemical applications. Its core value lies in the exceptional chemical and thermal stability provided by the CF3 polymer chain ends, combined with a precise equivalent weight of 870 g/mol SO3H for optimal proton conductivity. This product is essential for researchers and engineers in the fuel cell, electrolyzer, and specialty chemical processing industries who require reliable, high-purity membrane components.

Application

• Proton Exchange Membrane Fuel Cells (PEMFC): As the central electrolyte membrane for hydrogen fuel cells, particularly in high-temperature PEMFC (HT-PEMFC) designs.
• Water Electrolysis: Serving as the proton-conducting separator in Proton Exchange Membrane (PEM) electrolyzers for high-efficiency hydrogen production.
• Flow Batteries: Utilized as the ion-selective membrane in vanadium redox and other advanced flow battery systems for energy storage.
• Chemical Sensors and Analyzers: Acting as a selective barrier or electrolyte in electrochemical sensors for gas detection and process analysis.
• Chlor-Alkali Membrane Cells: Potential use as a durable membrane in electrochemical chlor-alkali processes.
• Direct Methanol Fuel Cells (DMFC): Employed as a membrane with low methanol crossover for portable power applications.
• Research & Development: A critical material for academic and industrial R&D in electrochemistry, membrane science, and next-generation energy technologies.

Quality Control

Every batch of Aquivion E87-05S membrane is manufactured under stringent quality systems. Our products undergo rigorous quality testing to ensure compliance with industry standards for electrochemical materials. Key parameters such as equivalent weight, thickness uniformity, proton conductivity, and mechanical integrity are verified. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This membrane is hygroscopic (moisture-sensitive) and should be stored in a cool, dry place at a controlled room temperature (15-25°C). The original protective liner should remain in place until use to prevent contamination, dehydration, or physical damage. Store away from strong acids and organic solvents.
