{"product_id":"cfbeefcaemfaa3","title":"Anion-Exchange Membrane (Fumasep, FAA-3 Series) for Flow Battery, Electrodialysis, Electrolyzer, and Fuel Cell, CFBEEFCAEMFAA3","description":"\u003cp\u003eThe Fumasep FAA-3 series is a family of hydrocarbon-based anion exchange membranes (AEMs) based on a polyaromatic backbone with quaternary ammonium functional groups. Produced by Fumatech BWT, they are the industry standard for alkaline electrolysis, fuel cells, and CO2 reduction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAA-3-30 and FAA-3-50 (Non-Reinforced)\u003c\/strong\u003e: These are \"homogeneous\" films, meaning they consist purely of the ion-exchange polymer without an internal fabric mesh. (1) \u003cstrong\u003ePros\u003c\/strong\u003e: Lowest possible electrical resistance (ASR) because there is no \"dead space\" taken up by non-conductive reinforcement fibers. (2) \u003cstrong\u003eCons\u003c\/strong\u003e: They are prone to significant swelling and are mechanically delicate. It is best to be used for small-scale laboratory research where you want to minimize voltage losses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAA-3-PE-30 (The \"Power\" Reinforced Membrane)\u003c\/strong\u003e: This grade uses an ultra-thin Polyethylene (PE) reinforcement. It allows the membrane to stay at 30 μm (the same as the unreinforced FAA-3-30) while providing enough mechanical strength to prevent tearing during stack assembly. It can be mainly used for multi-cell stacks where high efficiency is required but manual handling of unreinforced 30 μm films is too risky.\u003c\/p\u003e\n\u003cp\u003eFAA-3-PK Series (75 and 130 μm): These membranes are reinforced with a woven PEEK (Polyetheretherketone) mesh. PEEK mesh is highly resistant to heat and chemicals, in which the skeleton ensuring the membrane does not sag or stretch even in large-format industrial frames. These reinforced membranes are suitable for industrial bipolar electrodialysis (EDBM) or high-pressure water electrolyzers where the membrane must withstand pressure differentials between chambers.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003eCFBEEFCAEMFAA330\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003eCFBEEFCAEMFAA3PE30\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eCFBEEFCAEMFAAFAA350\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003eCFBEEFCAEMFAA3PK75\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eMembrane Name\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003eFAA-3-30\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003eFAA-3-PE-30\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eFAA-3-50\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003eFAA-3-PK-75\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eThickness (um)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003e26-34\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003e26-34\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e45-55\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003e70-80\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eReinforcement\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003eNo (Self-Supporting)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003eYes (PE Mesh)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eNo (Self-Supporting)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003eYes (Peek Mesh)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eDimensional Swelling \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003e\u0026lt;2%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003e\u0026lt;1%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e\u0026lt;2%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003e\u0026lt;2%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eArea Resistance (Cl-, Ω·cm²)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003e\u0026lt;2.0\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003e\u0026lt;1.3\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e0.6-1.5\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003e1.2-2.0\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eElectrical Conductivity (Cl-, mS\/cm)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003e\u0026gt;5.0\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003e\u0026gt;2.0\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e4.5-6.5\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003e\u0026gt;1.5\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eIon Exchange Capacity (IEC)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003e1.67-2.04 meq\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003e1.4-1.6 meq\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e1.6-2.1 meq\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18%;\"\u003e\n\u003cp\u003e1.2-2.0 meq\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 15%;\"\u003e\u003cem\u003eKey Characteristics \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 21.027%;\"\u003e\n\u003cp\u003eBalanced thin-film performance.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 18.973%;\"\u003e\n\u003cp\u003eReinforced but ultra-thin;
