{"product_id":"caefcaedp","title":"Anion Exchange Dispersion (PiperION-A5, 5 wt%) for Alkaline Electrolyzer and Fuel Cell, 10 mL\/bottle, CAEFCAEDP","description":"\u003cp\u003ePiperION is a commercial line of anion exchange ionomers and membranes developed by Versogen. It is based on a specialized class of polymers known as poly(aryl piperidinium) (PAP). Because of its high chemical stability and ionic conductivity, it is a leading material for alkaline electrochemical devices, particularly those that aim to avoid expensive platinum-group metals (PGM).\u003c\/p\u003e\n\u003cp\u003eThe core innovation of PiperION is its ether-bond-free rigid aromatic backbone. Most traditional anion exchange membranes (AEMs) fail because their ether bonds (C-O-C) are susceptible to nucleophilic attack by hydroxide ions (OH-) in alkaline environments. (1) \u003cstrong\u003eBackbone\u003c\/strong\u003e: A rigid aryl (aromatic) chain without ether linkages, providing extreme alkaline stability. (2) \u003cstrong\u003eCationic Group\u003c\/strong\u003e: The piperidinium cation (a six-membered ring containing nitrogen) is used as the ion-exchange site. Its cyclic structure and lack of β-hydrogens (in certain configurations) make it highly resistant to Hofmann elimination, a common degradation pathway for AEMs.\u003c\/p\u003e\n\u003cp\u003ePiperION ionomers are primarily used to create the Catalyst Layer (CL) in Membrane Electrode Assemblies (MEAs): (1) \u003cstrong\u003eAEM Water Electrolyzers (AEMWE)\u003c\/strong\u003e: Enables hydrogen production using low-cost catalysts like Nickel or Iron instead of Iridium. (2) \u003cstrong\u003eAlkaline Exchange Membrane Fuel Cells (AEMFC)\u003c\/strong\u003e: Allows for the use of non-platinum catalysts (e.g., Silver or Nickel), significantly lowering the cost of the fuel cell stack. (3) \u003cstrong\u003eCO2 Electrolysis\u003c\/strong\u003e: Used in systems that convert CO2 into syngas, ethylene, or formic acid. (4) \u003cstrong\u003eDirect Ammonia Fuel Cells (DAFC)\u003c\/strong\u003e: Highly stable in the presence of ammonia and concentrated alkaline fuels.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 304.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAEFCAEDP (C-AEFC-AEDP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 51.6px;\"\u003e\n\u003ctd style=\"width: 35.9712%; height: 51.6px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 51.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CAEFCAEDP_02_160x160.png?v=1771401821\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eTransparent Liquid \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: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003eSolvent\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eOrganic (undisclosed)\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: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003eConcentration\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e5 wt%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003eFunction Group\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003ePiperidinium cation\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: 35.9712%; height: 35.6px;\"\u003e\u003cem\u003eCounter Ion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCarbonate\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 35.9712%; height: 39.2px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8489%; height: 39.2px;\"\u003e10 mL\/bottle (the solid powder form with 0.4 g\/bottle also can be supplied upon request)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the anion exchange dispersion in a dry place (glovebox is the best option). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acselectrochem.4c00225\"\u003eL.
