{"product_id":"cefcetptc","title":"Platinum\/Carbon (Pt\/C, Tanaka) Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCETPtC","description":"\u003cp\u003eTanaka Kikinzoku Kogyo (TKK) is one of the world's leading manufacturers of high-performance Pt\/C (Platinum on Carbon) electrocatalysts, widely recognized for their high platinum dispersion and durability in both PEM fuel cells (PEMFC) and electrolyzers (PEMWE).\u003c\/p\u003e\n\u003cp\u003eIn fuel cell applications, Tanaka Pt\/C catalysts are utilized at both electrodes, though the specific grade choice depends on the performance target. (1)\u003cstrong\u003e Anode (HOR)\u003c\/strong\u003e: Typically uses TEC10E50E or similar high-surface-area catalysts. Because the Hydrogen Oxidation Reaction is fast, lower loadings can be used while maintaining high efficiency. (2) \u003cstrong\u003eCathode (ORR)\u003c\/strong\u003e: This is the most demanding environment. Tanaka’s PtCo (Platinum-Cobalt) alloy catalysts (e.g., TEC36E52) are increasingly favored for automotive cathodes because they offer significantly higher Oxygen Reduction Reaction activity than pure Pt\/C. (3) \u003cstrong\u003eCarbon Corrosion Resistance\u003c\/strong\u003e: For systems requiring extreme durability (e.g., heavy-duty trucks), Tanaka offers graphitized carbon supports that are more resistant to oxidation during start-stop cycles than traditional carbon black.\u003c\/p\u003e\n\u003cp\u003eIn PEM electrolyzers, Tanaka Pt\/C is strictly used as the Cathode Catalyst for the Hydrogen Evolution Reaction (HER). (1) \u003cstrong\u003eCathode Performance\u003c\/strong\u003e: TEC10E50E is a common choice for electrolyzer cathodes because it enables current densities as high as 2.0 A\/cm2 with very low overpotential. (2) \u003cstrong\u003eCrossover Prevention\u003c\/strong\u003e: A major innovation from Tanaka (recognized with the 2025 Technology Award) is a new catalyst technology that prevents \"hydrogen crossover\". This allows for thinner membranes (increasing efficiency) without risking the safety issues of hydrogen gas leaking into the oxygen side. (3) \u003cstrong\u003eAnode Note\u003c\/strong\u003e: Tanaka does not use Pt\/C for the electrolyzer anode; instead, they provide specialized Iridium Oxide (IrOx) catalysts (e.g., TEC77100) to withstand the highly oxidative environment.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%;
