{"product_id":"chtefciempbi","title":"Economic Polybenzimidazole (PBI) Ion-Exchange Membrane for High-Temperature Electroyzer and Fuel Cell, CHTEFCIEMPBI","description":"\u003cp\u003ePolybenzimidazole (PBI) is a high-performance polymer that has revolutionized electrochemical systems by enabling operation at \"intermediate\" to \"high\" temperatures (120°C to 200°C). While standard fuel cells (like Nafion-based PEMFCs) are limited to below 100°C, PBI-based systems offer significant advantages in both energy production (fuel cells) and hydrogen production (electrolyzers).\u003c\/p\u003e\n\u003cp\u003eIn high-temperature electrolyzer field, PBI is increasingly used in electrolysis to split water into hydrogen and oxygen more efficiently. Its features are: (1) \u003cstrong\u003eFaster Kinetics\u003c\/strong\u003e: High temperatures reduce the \"overpotential\" (extra energy) needed to trigger the chemical reaction. (2)\u003cstrong\u003e Thermal Integration\u003c\/strong\u003e: High-temperature electrolysis can use waste heat from industrial processes to provide part of the energy needed for the reaction, significantly lowering electricity costs. (3) \u003cstrong\u003eDurability\u003c\/strong\u003e: PBI acts as a stable separator that prevents the product gases (H2 and O2) from mixing, which is a major safety requirement in high-pressure electrolysis.\u003c\/p\u003e\n\u003cp\u003eIn high-temperature fuel cell application, PBI allows the system to operate at 160°C–180°C. This higher temperature provides three game-changing benefits: (1) \u003cstrong\u003eCO Tolerance\u003c\/strong\u003e: At 80°C, even 10 ppm of Carbon Monoxide (CO) can poison the platinum catalyst. At 180°C, the cell can tolerate up to 3% CO, allowing the use of less-pure hydrogen from reformed fuels (like methanol or natural gas). (2) \u003cstrong\u003eSimplified Cooling\u003c\/strong\u003e: Because the cell is much hotter than the ambient air, the radiator size can be reduced by up to 50%. (3) \u003cstrong\u003eWater Management\u003c\/strong\u003e: There is no \"liquid water\" to flood the pores; water is produced as steam and easily exhausted.\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\u003eCHTEFCIEMPBI (C-HTEFC-IEMPBI)\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 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 40 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\u003eIon Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e80-105 mS\/cm\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 Absorption Amount\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e400 wt%\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\u003eTensile Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e100-130 MPa\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\u003eThermal Stability\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~350 °C\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\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\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003eThe membrane pack should be stored at 18-28°C and relative humidity is 30-70%. \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.
