{"product_id":"caefcfbaeidfaa3","title":"Anion Exchange Ionomer Dispersion (10 wt%, Fumion FAA-3) for Alkaline Electrolyzer, Fuel Cell and Flow Battery, 25 mL\/bottle, CAEFCFBAEIDFAA3","description":"\u003cp\u003eFumatech’s FAA-3 (specifically the FAA-3-SOLUT-10 dispersion) is one of the most established and \"classic\" anion exchange ionomers used in global research. It is a polyaromatic polymer with quaternary ammonium groups, widely regarded as the industry benchmark for Alkaline Exchange Membrane Fuel Cells (AEMFC) and Water Electrolyzers.\u003c\/p\u003e\n\u003cp\u003eThe FAA-3 series is based on a polyaromatic backbone (non-perfluorinated). Unlike the imidazolium-based Sustainion or the piperidinium-based PiperION, FAA-3 uses quaternary ammonium functional groups. It has backbone of Aryl-ether-ketone (Polycyclic aromatic) and functional groups of Benzyl trimethyl ammonium. Typically it is supplied as a 10% w\/w solution in N-Methyl-2-pyrrolidone (NMP) or an Ethanol\/Water mixture.\u003c\/p\u003e\n\u003cp\u003eIn AEM Water Electrolyzers (AEMWE), it is the most common application for FAA-3 ionomer. It acts as the ion-conducting binder in the catalyst layers of electrolyzers that split water into hydrogen and oxygen. Moreover, it allows the use of non-precious metal catalysts (like Nickel, Iron, and Cobalt) instead of expensive Iridium or Platinum. It creates the \"triple-phase boundary\" where the liquid water, the solid catalyst, and the gas bubbles meet, ensuring hydroxide ions (OH-) can move freely to the membrane.\u003c\/p\u003e\n\u003cp\u003eFAA-3 is a staple in AEMFC research, where hydrogen and oxygen are recombined to generate electricity and water. (1) \u003cstrong\u003eDirect Methanol\/Ethanol Fuel Cells\u003c\/strong\u003e: It is frequently used in research for Direct Alcohol Fuel Cells. FAA-3 shows good resistance to alcohol crossover compared to some cation-exchange alternatives. (2) \u003cstrong\u003ePerformance\u003c\/strong\u003e: It provides a stable environment for Oxygen Reduction Reaction (ORR) catalysts, helping to drive down the cost of fuel cell stacks.\u003c\/p\u003e\n\u003cp\u003eIn the burgeoning field of carbon capture and utilization, FAA-3 is used to develop electrodes that convert CO2 into value-added chemicals like Carbon Monoxide (CO), Ethylene (C2H4), or Formate. FAA-3 can help suppress the unwanted Hydrogen Evolution Reaction (HER), thereby increasing the \"Faradaic Efficiency\" (selectivity) for carbon products.\u003c\/p\u003e\n\u003cp\u003eFAA-3 also can be used in alkaline redox flow batteries (e.g., Zinc-Iron or organic flow batteries) as an electrode binder to suppress the crossover mitigation. Its polyaromatic backbone is effective at blocking the crossover of bulky active species (like ferrocyanide or organic molecules) while still allowing small charge-carrying ions to pass through.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eCAEFCFBAEIDFAA3 (C-AEFCFB-AEIDFAA3)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CAEFCFBAEIDFAA3_chemical_structure_160x160.png?v=1771465222\" alt=\"\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eBrown, Transparent Solution \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eSolvent\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e10 wt% in \u003cstrong\u003eEthanol\u003c\/strong\u003e or\u003cstrong\u003e NMP\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eSolution Viscosity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u0026lt; 20 mPa s\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eFunctional Groups\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eQuaternary Ammonium Group\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCounter Ion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eBromide (Br-)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e25 mL\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the FAA-3 alkaline anion exchange dispersion in a dry place (glovebox is the best option). \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775320315482\"\u003eJ.
