{"product_id":"cefcehcpsgdl","title":"Economic Hydrophobic Carbon Paper Sheet (L 100mm * W 100mm * T 0.23mm) with Gas-Diffusion Layer (GDL) for Electrolyzer and Fuel Cell, CEFCEHCPSGDL","description":"\u003cp\u003eIn electrochemical systems, carbon paper serves as a macroporous substrate for the Gas Diffusion Layer (GDL), acting as the critical interface between the flow field and the catalyst layer. While it is a standard component in fuel cells, its use in electrolyzers is strictly limited by the operating environment.\u003c\/p\u003e\n\u003cp\u003eA high-performance GDL typically consists of a bilayer structure: (1) \u003cstrong\u003eMacroporous Substrate\u003c\/strong\u003e: A non-woven sheet of carbon fibers (e.g., Toray, Sigracet, or AvCarb) providing mechanical support and electrical\/thermal conductivity. (2) \u003cstrong\u003eMicroporous Layer (MPL)\u003c\/strong\u003e: A thin coating of carbon black and a hydrophobic agent (typically 5–15% PTFE) applied to one side. It reduces contact resistance with the catalyst, protects the membrane from fiber perforation, and aids in water management.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 120.713px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 52.5px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 52.5px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 52.5px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEFCEHCPSGDL (C-EFC-EHCPSGDL)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 56.4125px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 56.4125px;\"\u003e\u003cem\u003eSheet Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 56.4125px;\"\u003e\n\u003cp\u003eL 100mm * W 100mm * T 0.23mm\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003eOther sheet dimensions can also be supplied upon request. \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 11.8px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 11.8px;\"\u003e\u003cem\u003eStructure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 11.8px;\"\u003e\n\u003cp\u003eCarbon Paper\/MPL\/PTFE\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePorosity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e65%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eArea Resistance (mΩ cm)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e15\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eTensile Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e~10 N\/cm (MD), 7 N\/cm (TD)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e1 pcs\/pack or 5 pcs\/pack\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","brand":"SEN","offers":[{"title":"1 pcs\/pack","offer_id":47404160286950,"sku":"CEFCEHCPSGDL1","price":39.0,"currency_code":"USD","in_stock":true},{"title":"5 pcs\/pack","offer_id":47404160319718,"sku":"CEFCEHCPSGDL5","price":149.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CEFCEHCPSGDL_main.png?v=1772407716","url":"https:\/\/echemsupplies.com\/products\/cefcehcpsgdl","provider":"EChem Supplies","version":"1.0","type":"link"}
