{"product_id":"cefcceptb","title":"Platinum Black Coated Electrode (2 mg\/cm2) for Electrolyzer and Fuel Cell, CEFCCEPtB","description":"\u003cp\u003ePlatinum Black coated electrodes are high-performance components specifically designed for environments where standard carbon-supported catalysts (Pt\/C) might fail due to corrosion or where extremely high power density is required. Unlike Pt\/C, which uses carbon as a scaffold, Platinum Black is composed of pure, finely divided metallic platinum.\u003c\/p\u003e\n\u003cp\u003eWoven carbon cloth is favored for its 3D architecture and durability. (1) \u003cstrong\u003eFlexibility\u003c\/strong\u003e: It can be bent and compressed without cracking, making it ideal for \"home-built\" cells or flexible devices. (2) \u003cstrong\u003eMass Transport\u003c\/strong\u003e: The macro-pores between the woven threads allow for excellent liquid water removal. This is critical if the electrode is used as a fuel cell cathode where water is a byproduct. (3) \u003cstrong\u003eLoading\u003c\/strong\u003e: Platinum Black can be \"slurried\" and deeply embedded into the weave, creating a very thick, high-capacity active layer.\u003c\/p\u003e\n\u003cp\u003eCarbon paper (like Toray or Sigracet) is the standard for precision and consistency. (1) \u003cstrong\u003eUniformity\u003c\/strong\u003e: It provides a perfectly flat surface, ensuring that the distance between the anode and cathode is exactly the same across the entire cell. (2) \u003cstrong\u003eOhmic Resistance\u003c\/strong\u003e: It generally has lower through-plane resistance than cloth, making it better for high-efficiency, high-current-density stacks. (3) \u003cstrong\u003eFragility\u003c\/strong\u003e: It is brittle. Once it is coated with Platinum Black, it must be handled carefully to avoid snapping the fibers.\u003c\/p\u003e\n\u003cp\u003eThe main applications for the Pt\/C are (1) \u003cstrong\u003eUnitized Regenerative Fuel Cells\u003c\/strong\u003e; (2) \u003cstrong\u003eDirect Methanol Fuel Cells (DMFC); \u003c\/strong\u003eand (3)\u003cstrong\u003e Water Electrolyzer. \u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 101.819%; height: 524.85px;\"\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\u003eCEFCCEPtB\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\u003ePlatinum black wit fuel cell grade\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\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\u003e2 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\u003eL10cm * W10cm \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(Other sizes, 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 platinum black 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:\/\/iopscience.iop.org\/article\/10.1149\/1.2210590\/meta\"\u003eK.
