FAPQ-330 Anion Exchange Membrane

Thinner than its FAP-450 sibling, the FAPQ-330 anion exchange membrane is engineered for vanadium and organic redox flow battery configurations where power density is the priority. Its 26-34 µm profile pushes area resistance below 0.5 Ω cm², supporting higher current densities without the ohmic penalty of thicker membranes, while retaining the oxidative durability needed for long-duration cycling. Delivered dry on a PET carrier with no pretreatment step, it is built for fast turnaround between test campaigns.

• High Power Density: Sub-0.5 Ω cm² area resistance in Cl- form supports high-current-density RFB testing.
• Slim 30 µm Profile: Thinner than the FAP-450 for lower ohmic losses at comparable mechanical robustness.
• Verified Integrity: Bubble point >3 bar confirms defect-free, pinhole-free sheets prior to cell assembly.
• Strong Mechanicals: >35 MPa tensile strength and >200% elongation at break simplify cutting and handling.
• Dual Chemistry Fit: Suited to both vanadium and organic redox flow battery electrolytes.
• Ready-to-Cut: Supplied in standard sheets or pre-cut for Redox Flow’s X-Stack, S-Stack, and 3-compartment X-Cell hardware.
