{"product_id":"chtefccempbibcp","title":"Polybenzimidazole (PBI) Cation-Exchange Membrane (BASF Celtec-P) for High-Temperature Electroyzer and Fuel Cell, CHTEFCCEMPBIBCP","description":"\u003cp\u003eThe BASF Celtec®-P series represents a specialized class of High-Temperature Proton Exchange Membranes (HT-PEM). Unlike standard Nafion-style membranes that rely on liquid water to conduct protons, Celtec®-P is based on polybenzimidazole (PBI) doped with phosphoric acid (H3PO4). This unique chemistry allows the membrane to operate at temperatures between 120°C and 180°C, fundamentally changing the design and efficiency of electrochemical systems.\u003c\/p\u003e\n\u003cp\u003eThe most significant application for Celtec®-P is in stationary and portable fuel cells that run on reformed hydrogen (from methanol, natural gas, or propane). (1) \u003cstrong\u003eExtreme Carbon Monoxide (CO) Tolerance\u003c\/strong\u003e: At standard temperatures (80°C), even 10 ppm of CO can poison a platinum catalyst. At 160°C, the Celtec®-P membrane allows the catalyst to tolerate up to 3% CO. This eliminates the need for expensive, complex \"deep purification\" stages in a fuel reformer. (2) \u003cstrong\u003eSimplified Water Management\u003c\/strong\u003e: Because the membrane conducts protons via phosphoric acid rather than liquid water, there is no need for humidifiers, water pumps, or complex hydration controls. The system can operate in very dry or very cold environments without \"flooding\" or freezing. (3) \u003cstrong\u003eHeat Recovery\u003c\/strong\u003e: The high-grade waste heat (160°C+) can be used for space heating or water heating (Combined Heat and Power - CHP), pushing total system efficiency over 80%.\u003c\/p\u003e\n\u003cp\u003eOther applications, such as \u003cstrong\u003eMethanol Reformer Integration, Electrochemical Hydrogen Compression (EHC), and Steam Electrolysis. \u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 182.637px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 40.2375px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 40.2375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCHTEFCCEMPBIBCP (C-HTEFC-CEM-PBIBCP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eChemical Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CRFBIEMPBI_molecular_structure_160x160.png?v=1768589215\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eBrown or Dark Brown\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;60000 (IV \u0026gt;4.5 dL\/g)\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: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eT 400 um * L 100mm * W 100 mm (Other membrane sizes can be supplied upon request)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eOperation Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e120–180 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003ePretreatment Status\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003ePhosphoric acid doped (sol-gel doping)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNo additional treatment before use\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eProton Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~0.1 S\/cm (at 160°C, anhydrous)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eAcid Concentration\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e55 wt% (+\/-4 wt%)\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: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1 pcs\/pack (beside the standard sheet size of 10 cm*10cm, other sizes, such as 20cm*20cm can also be supplied). \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e(1）\u003ca href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsaem.3c00522\"\u003eK.
