{"product_id":"cpemefccepfsaid","title":"Cation Exchange PFSA Ionomer Dispersion (Aquivion) for Proton-Exchange Membrane Electrolyzer and Fuel Cell, 10 mL\/bottle, CPEMEFCCEPFSAID","description":"\u003cp\u003eAquivion® is a line of high-performance Perfluorinated Sulfonic Acid (PFSA) ionomers and membranes produced by Solvay. While it shares the same fluorinated DNA as Nafion, it belongs to the \"Short Side Chain\" (SSC) family of ionomers, which gives it distinct thermal and electrochemical advantages.\u003c\/p\u003e\n\u003cp\u003eThe primary difference between Aquivion and standard Nafion is the length and structure of the side chain attached to the PTFE backbone. (1) \u003cstrong\u003eStandard Nafion (Long Side Chain)\u003c\/strong\u003e: Has a long, flexible side chain containing an additional ether group. (2)\u003cstrong\u003e Aquivion (Short Side Chain)\u003c\/strong\u003e: Has a significantly shorter, more rigid side chain with no intermediate ether linkage.\u003c\/p\u003e\n\u003cp\u003eBecause the side chains are shorter and more compact, Aquivion exhibits several superior physical properties compared to traditional PFSA ionomers: (1) \u003cstrong\u003eHigher Glass Transition Temperature (Tg)\u003c\/strong\u003e: Aquivion has a Tg of approximately 140°C to 150°C (compared to ~110°C for Nafion). This allows fuel cells and electrolyzers to operate at higher temperatures without the polymer softening or losing structural integrity. (2) \u003cstrong\u003eEnhanced Crystallinity\u003c\/strong\u003e: The shorter chains allow the PTFE backbones to pack more tightly. This results in better mechanical strength and lower gas crossover even when the membrane is thin. (3) \u003cstrong\u003eHigher Proton Conductivity\u003c\/strong\u003e: Aquivion can be manufactured with a lower Equivalent Weight (EW)—as low as 700–800 g\/eq—without becoming physically unstable or dissolving in water. A lower EW means more acid sites and higher power density.\u003c\/p\u003e\n\u003cp\u003eThe main applications for the Aquivion PFSA ionomer are: (1) \u003cstrong\u003eHigh-Temperature PEM Fuel Cells\u003c\/strong\u003e: Enables operation above 95°C, which simplifies cooling systems and improves tolerance to impurities in the hydrogen gas. (2) \u003cstrong\u003ePEM Water Electrolysis (PEMWE)\u003c\/strong\u003e: Its high mechanical strength allows for thinner membranes, reducing the voltage required to split water and increasing efficiency. (3) \u003cstrong\u003eVanadium Redox Flow Batteries (VRFB)\u003c\/strong\u003e: The high crystallinity helps block the crossover of vanadium ions, leading to longer battery life and better capacity retention\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%;
