{"product_id":"cefcceptc","title":"Platinum\/Carbon (Pt\/C, 60 wt%) Coated Electrode (0.5 mg\/cm2) for Electrolyzer and Fuel Cell, CEFCCEPtC","description":"\u003cp\u003ePlatinum on Carbon (Pt\/C) is the industry-standard catalyst for handling the hydrogen-side reactions in both fuel cells and electrolyzers. The role of the Pt\/C electrode changes dramatically depending on whether it is \"pushing\" electrons (electrolysis) or \"pulling\" them (fuel cell).\u003c\/p\u003e\n\u003cp\u003eIn an PEM electrolyzer, (1) \u003cstrong\u003eHydrogen Evolution (HER)\u003c\/strong\u003e: Pt\/Vulcan is the standard cathode for water splitting. (2) \u003cstrong\u003eCathode Environment\u003c\/strong\u003e: Since the cathode operates at low (reducing) potentials, the Vulcan XC-72 carbon is extremely stable and can last for tens of thousands of hours without degrading\u003c\/p\u003e\n\u003cp\u003eIn PEM fuel cell, (1) \u003cstrong\u003eOxygen Reduction (ORR)\u003c\/strong\u003e: Most commercial cathode catalysts are 20% to 60% Pt\/Vulcan. The carbon must provide a stable path for electrons to reach the oxygen molecules. (2) \u003cstrong\u003eDurability\u003c\/strong\u003e: At the cathode, the high voltage and moisture can cause the Vulcan XC-72 to slowly corrode (carbon oxidation). Researchers often use \"Graphitized\" Vulcan (heat-treated at \u0026gt;1000°C) to make the carbon more resistant to this decay.\u003c\/p\u003e\n\u003ctable style=\"width: 101.819%; height: 524.85px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEFCCEPtC\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: 30.2013%; height: 35.6px;\"\u003e\u003cem\u003eElectrode Active material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e60 wt% platinum nanoparticles on Vulcan XC-72 carbon black\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 197.6px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 197.6px;\"\u003e\u003cem\u003eCarbon Cloth Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 197.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 410 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDensity: 200 g\/m2\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAir Permeability: \u0026lt; 55 s\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFiber length: 35 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eElectrical Resistivity (through plane) \u0026lt; 13 mΩcm²\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMicroporous layer is located at the catalyst side\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 162px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 162px;\"\u003e\u003cem\u003eCarbon Paper Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 162px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 215 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDensity: 70 g\/m2\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWater Contact Angle (MPL side): \u0026gt; 130°\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSubstrate PTFE Treatment: 5 wt%\u003c\/p\u003e\n\u003cp\u003eMicroporous layer is located at the catalyst side\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.2013%;\"\u003e\u003cem\u003eTitanium Felt Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 250 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePorosity: 60-70%\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFiber length: 70 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFiber diameter: 25-50 um\u003c\/span\u003e\u003cspan\u003e\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: 30.2013%; height: 35.6px;\"\u003e\u003cem\u003eLoading Amount\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e0.5 mg\/cm2\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: 30.2013%; height: 35.6px;\"\u003e\u003cem\u003eElectrode Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e L 10cm * W 10cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(Other sizes, such as 20cm*20cm, 30cm * 30cm, 40cm*40cm can be supplied upon request)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.85px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 22.85px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 22.85px;\"\u003e1 pcs\/pack\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 Pt\/C coated electrodes in a dry place.\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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0013468613010943\"\u003eS.
