{"product_id":"caefcaemna","title":"Anion-Exchange Membrane (NEXIONIC, NA20-80) for Alkaline Electrolyzer and Fuel Cell, CAEFCAEMNA","description":"\u003cp\u003eThe NEXIONIC NA series of anion exchange membranes (AEMs) represents a transition in the industry toward high-stability, hydrocarbon-based materials. While \"NA\" often specifically refers to the commercial dispersion (liquid) form used for catalyst inks, the series also includes a range of solid membranes designed for durability in alkaline environments. \u003c\/p\u003e\n\u003cp\u003eThe \"NA\" series membranes are built on the Quaternary Ammonium Poly(phenylene terphenyl) or QAPPT chemical platform. (1)\u003cstrong\u003e Ether-Free Backbone\u003c\/strong\u003e: Unlike older AEMs that fail because hydroxide ions (OH-) attack the ether bonds in the polymer chain, the NA series uses an all-carbon aromatic backbone. (2) \u003cstrong\u003eSteric Protection\u003c\/strong\u003e: The positively charged ammonium groups are \"shielded\" by the bulky aromatic rings, preventing chemical degradation at high pH. (3) \u003cstrong\u003eHigh Conductivity\u003c\/strong\u003e: These materials are optimized for high Ion Exchange Capacity (IEC), allowing for fast ion movement even at lower relative humidity.\u003c\/p\u003e\n\u003cp\u003eThe main application of these NA membranes are: (1) \u003cstrong\u003eAEM Water Electrolysis (AEMWE)\u003c\/strong\u003e: Producing green hydrogen using non-precious catalysts (like Nickel or Cobalt). (2) \u003cstrong\u003eAEM Fuel Cells (AEMFC)\u003c\/strong\u003e: Generating power from hydrogen in an alkaline environment, allowing the use of cheaper catalysts than the Platinum required by Nafion.
