It is widely used in high-performance Redox Flow Batteries (RFBs), particularly the Vanadium Redox Flow Battery (VRFB), where it serves as a critical separator between the positive and negative electrolytes. \u003c\/p\u003e\n\u003cp\u003eUnlike traditional cation-exchange membranes (like Nafion), the FAPQ-330 is designed to conduct anions while significantly blocking the crossover of positively charged metal ions (like V2+, V3+, VO2+). This reduces self-discharge and maintains capacity over long cycles.\u003c\/p\u003e\n\u003cp\u003eThe FAPQ-330 membranes are widely used for redox flow battery due to the following reasons: (1) \u003cstrong\u003eLow Crossover\u003c\/strong\u003e: In Vanadium batteries, the crossover of vanadium ions leads to permanent loss of efficiency. Because this membrane is an Anion Exchanger, its fixed positive charges naturally repel the positive vanadium cations (the Donnan exclusion principle). (2) \u003cstrong\u003eEfficiency\u003c\/strong\u003e: It typically achieves Coulombic Efficiencies (CE) of \u0026gt;98% and supports higher current densities (100 - 250 mA\/cm2) compared to thicker or reinforced membranes. (3) \u003cstrong\u003eMechanical Stability\u003c\/strong\u003e: Despite being non-reinforced, it maintains good tensile strength (20-45 MPa) and low swelling, which prevents the membrane from wrinkling or tearing within the cell stack.\u003c\/p\u003e\n\u003cp\u003eThe FAPQ-330 membrane is specifically noted for being highly resistant to chlorine. (1) \u003cstrong\u003eElectrochemical Chlorine Production\u003c\/strong\u003e: Used in specialized cells where chlorine gas is a byproduct, which would normally degrade or \"bleach\" a standard exchange membrane. (2) \u003cstrong\u003eSeawater Electrolysis Research\u003c\/strong\u003e: It is used in lab-scale setups for seawater splitting or desalination research because it can handle the high chloride content without losing its mechanical integrity.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 192.637px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 40.2375px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 40.2375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCRFBEAEMFAPQ330 (C-RFBE-AEMFAPQ330)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eSlightly Opaque\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003eBacking Foil\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eSingle-side PET (need peeling off), no reinforcement layer\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003eT 30um * W 100mm * L 100mm (Other membrane sizes can be supplied upon request)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eCounter Ion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003eChloride \/ Methylsulfate\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eWeight Per Unit Area    \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cem\u003e4.0 – 5.0 mg cm^-2\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eArea Specific Resistance (ohm cm²)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt; 0.35 (0.5 M H2SO4)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003e\u0026lt; 0.35 (0.5 M H2SO4)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt; 85% (0.1 \/ 0.5 mol\/kg KCl at T = 25 °C)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eConductivity (0.5M H2SO4) \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e9-12 mS\/cm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 10px;\"\u003e\u003cem\u003eSelectivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 10px;\"\u003e\n\u003cp\u003e90-96% (0.1\/0.5 mol\/kg KCl)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eProton Transfer Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u0026gt; 5.500 μmol min^- 1 c m^-2\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eTensile Strength - max.
