It is widely regarded as a \"gold standard\" in laboratory and commercial research for Vanadium Redox Flow Batteries (VRFBs) and other acidic aqueous redox systems. The FAP-450 is a non-reinforced, partially fluorinated membrane. Its design focuses on balancing low electrical resistance with an exceptional ability to block the crossover of metal ions (like Vanadium). Its applications are mainly displayed below:\u003c\/p\u003e\n\u003cp\u003e(1) \u003cstrong\u003eVanadium Redox Flow Batteries (VRFB)\u003c\/strong\u003e: This is its most common use. Because it is an anion exchanger, it effectively blocks the positively charged vanadium ions from crossing over, which significantly reduces self-discharge and capacity decay.\u003c\/p\u003e\n\u003cp\u003e(2) \u003cstrong\u003eNon-Aqueous Redox Flow Batteries (NARFB)\u003c\/strong\u003e: Researchers often use FAP-450 in organic solvent systems (like acetonitrile) due to its chemical compatibility, though swelling behavior must be monitored.\u003c\/p\u003e\n\u003cp\u003e(3) \u003cstrong\u003eAcid Recovery \u0026amp; Electrodialysis\u003c\/strong\u003e: Used in processes requiring the transport of anions while blocking protons or metal cations in highly acidic environments.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 192.637px;\" width=\"100%\"\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\u003eCVRFBAEMFAP450 (C-VRFB-AEMFAP450)\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\u003eTransparent membrane\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\u003eBack Substrate\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 50um * 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\u003eAreal Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e7.5-8.5 mg\/cm2\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\u003ePlanar Resistivity (0.5M H2SO4)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e0.45-0.60 Ω · cm2\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 Transmission Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e2500-4500 umol \u003cspan\u003e· min-1 · cm-2\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\u003epH Stability \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003eStable when pH \u0026lt;4\u003c\/p\u003e\n\u003cp\u003eUnstable when pH\u0026gt;11 \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FuelCellStore","offers":[{"title":"Default Title","offer_id":47269996036326,"sku":"CRFBAEMFAP450","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CRFBAEMFAP450_main.png?v=1768494374","url":"https:\/\/echemsupplies.com\/products\/crfbaemfap450","provider":"EChem Supplies","version":"1.0","type":"link"}
