FAAM-PK-75 Anion Exchange Membrane

For alkaline electrolysis programs pushing into pressurized or long-duration testing, the FAAM-PK-75 pairs the same alkaline-stable chemistry as the FAAM-20 with a polyketone reinforcement layer that raises mechanical robustness for tougher operating conditions. At 60-80 µm it holds length swelling under 2% after extended exposure to 9 M KOH, while the reinforcement mesh supports higher differential pressures than unreinforced films. Supplied dry and unbacked, it activates in-cell or via pre-soak between stabilizing meshes.

• Reinforced for Pressure: PK (polyketone) reinforcement improves durability in pressurized alkaline electrolysis cells.
• Dimensionally Stable: <2% length increase after extended exposure to 9 M KOH keeps cell alignment consistent.
• High Modulus: >1000 MPa Young's modulus supports demanding mechanical handling during assembly.
• Thermally Robust: No oxidation below 250 °C when stored dry.
• Flexible Activation: Self-activates in-cell or via extended pre-soak in KOH between meshes/spacers.
• Multiple Cut Formats: Standard sheets or pre-cut for Redox Flow’s X-Stack, S-Stack, and 3-compartment X-Cell hardware.
