{"product_id":"cefcejmptc","title":"Platinum\/Carbon (Pt\/C, Johnson Matthey) Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCEJMPtC","description":"\u003cp\u003eJohnson Matthey (JM) is a global leader in the production of Platinum on Carbon (Pt\/C) electrocatalysts, primarily through their HiSPEC® product line. These catalysts are essential components in both energy generation (Fuel Cells) and energy storage\/production (Electrolyzers). \u003c\/p\u003e\n\u003cp\u003eIn a fuel cell, Pt\/C is used at both the anode and the cathode, but it serves different functions and faces different challenges at each. (1) \u003cstrong\u003eCathode (Oxygen Reduction Reaction - ORR)\u003c\/strong\u003e: This is the \"bottleneck\" of the fuel cell. Pt\/C is used to break the strong $O=O$ bonds. Because ORR is inherently slow, the cathode typically requires much higher platinum loading (often 0.4 mg\/cm2 or more) compared to the anode. (2) \u003cstrong\u003eAnode (Hydrogen Oxidation Reaction - HOR)\u003c\/strong\u003e: Platinum is exceptionally efficient at splitting H2. Because this reaction is fast, modern JM catalysts allow for \"thrifting\" (reducing) platinum levels at the anode to as low as 0.05 mg\/cm2 without significant performance loss. (3) \u003cstrong\u003eCarbon Support\u003c\/strong\u003e: JM uses specialized high-surface-area carbons (HSC) to disperse platinum nanoparticles (typically 2–5 nm). This maximizes the Electrochemical Surface Area (ECSA), which is critical for maximizing power density in automotive applications.\u003c\/p\u003e\n\u003cp\u003eWhile the anode of an electrolyzer requires iridium (as discussed previously), the cathode relies on platinum to facilitate the Hydrogen Evolution Reaction (HER). (1) \u003cstrong\u003eThe Cathode Catalyst\u003c\/strong\u003e: Pt\/C is the industry standard for the electrolyzer cathode. It takes the protons (H+) that have crossed the membrane and combines them with electrons to form pure hydrogen gas (H2). (2)\u003cstrong\u003e Stability\u003c\/strong\u003e: Unlike the fuel cell cathode, the electrolyzer cathode operates in a reducing environment, which is less corrosive for the carbon support. This allows for very high durability and long-term hydrogen production.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 336px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.9137%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEFCEJMPtC4000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEFCEJMPtC9100\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.9137%;\"\u003e\u003cem\u003eCatalyst Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e\n\u003cp\u003e\u003cspan\u003eHiSPEC4000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e\n\u003cp\u003e\u003cspan\u003eHiSPEC9100\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 29.6px;\"\u003e\n\u003ctd style=\"width: 32.9137%; height: 29.6px;\"\u003e\u003cem\u003ePlatinum Content\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%; height: 29.6px;\"\u003e40 wt% Pt on XC-72R\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e60 wt% Pt on high surface area carbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.9137%; height: 35.6px;\"\u003e\u003cem\u003eCatalyst BET Surface Area:\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e-\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e\n\u003cp\u003e\u003cspan\u003e80 m2\/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: 32.9137%; height: 35.6px;\"\u003e\u003cem\u003eMetal Crystallite Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~3.5 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~2.8 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 32.9137%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%; height: 19.6px;\"\u003e0.5 g\/bottle\u003c\/td\u003e\n\u003ctd style=\"width: 33.2734%;\"\u003e0.5 g\/bottle\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 powder 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:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsami.4c10430\"\u003eV.
