{"product_id":"cefceptcoc","title":"Platinum-Cobalt (Pt-Co, Premetek) Alloy on Carbon Black as Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCEPtCoC","description":"\u003cp\u003ePlatinum-Cobalt (Pt-Co) is currently widely regarded as the most successful Pt-alloy electrocatalyst for commercial applications. It is the specific catalyst used in the cathode of the Toyota Mirai fuel cell stack, proving its viability for mass production. \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eIn Proton Exchange Membrane Fuel Cell (PEMFC), Pt-Co is primarily a cathode material for the Oxygen Reduction Reaction (ORR). (1) \u003cstrong\u003eSuperior Activity\u003c\/strong\u003e: Pt-Co typically exhibits 3x to 5x higher mass activity than pure Pt\/C. The cobalt atoms cause a \"compressive strain\" on the platinum lattice, which optimizes the distance between Pt atoms. This makes it easier for oxygen to bind, react, and release as water. (2) \u003cstrong\u003eGeometric \u0026amp; Electronic Effects\u003c\/strong\u003e: The addition of Cobalt shifts the d-band center of the Platinum. This prevents oxygen-containing intermediates (like OH) from sticking too strongly to the surface, which \"frees up\" more active sites for new oxygen molecules. (3) \u003cstrong\u003eCommercial Maturity\u003c\/strong\u003e: Major suppliers like TANAKA and Johnson Matthey offer Pt-Co as a standard product (e.g., 30% to 50% metal loading) because its synthesis is more reproducible at scale compared to many other alloys.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn electrolyzers, Pt-Co alloy electrocata;ysts' roles are: (1) \u003cstrong\u003eCathode (HER)\u003c\/strong\u003e: It can be used for the Hydrogen Evolution Reaction (HER), but since pure Pt\/C is already extremely efficient for HER, the performance gains from alloying with Cobalt are less significant than they are for the fuel cell's ORR. (2) \u003cstrong\u003eCobalt Leaching\u003c\/strong\u003e: A major risk in electrolyzer systems is the acidic environment causing Cobalt ions (Co^2+) to leach out. If these ions migrate into the proton exchange membrane, they can reduce its conductivity and lead to premature failure. (3) \u003cstrong\u003eSolution\u003c\/strong\u003e: To mitigate this, manufacturers use acid-etching or de-alloying treatments during production. This creates a \"Pt-skin\" (a thick layer of pure Pt on the outside of the particle) that protects the Pt-Co alloy core from the harsh environment.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%;
