FAA-3-50 Anion Exchange Membrane

The FAA-3-50 is a general-purpose anion exchange membrane covering a wide span of electrochemical applications, from AEM fuel cells and AEM water electrolysis to redox flow battery research. At 45-55 µm it balances broad pH stability from 1 to 14 with moderate area resistance and good selectivity, making it a practical default choice when a project's exact membrane requirements are still being defined. Delivered dry in bromide form with a PEG stabilizer, it should be soaked before use and kept hydrated once wetted.

• Broad pH Range: Stable from pH 1 to 14, suiting a wide variety of electrolyte chemistries.
• Multi-Application Fit: Suitable for AEM fuel cells, AEM water electrolysis, and redox flow battery testing.
• Moderate Resistance: <2.5 Ω cm² area resistance (Cl⁻ form) supports general-purpose screening work.
• Good Selectivity: >90% selectivity limits ion crossover across the supported chemistries.
• Simple Handling: Ships dry with a PEG stabilizer; soak in DI water before use and keep hydrated thereafter.
• Ready-to-Cut Formats: Standard sheets or pre-cut for Redox Flow’s X-Stack, S-Stack, and 3-compartment X-Cell hardware.
