While Pt-Co and Pt-Ni focus on high activity for pure hydrogen, Pt-Ru is built for resilience and chemical cleaning.\u003c\/p\u003e\n\u003cp\u003eIn a standard Hydrogen PEM Fuel Cell, Pt-Ru is almost always used at the anode. (1) \u003cstrong\u003eThe Problem with Pure Pt\u003c\/strong\u003e: If your hydrogen fuel is \"dirty\" (reformed from natural gas), it contains trace amounts of CO. CO sticks to pure Platinum 100 times more strongly than Hydrogen, which \"poisoning\" the surface and killing the reaction. (2) \u003cstrong\u003eThe Bifunctional Mechanism\u003c\/strong\u003e: Ru provides a \"cleaning\" service. It dissociates water molecules at a much lower voltage than Pt to form hydroxyl groups (-OH). These -OH groups react with the CO stuck on the neighboring Pt atoms, oxidizing it into CO2 and freeing up the Pt to process hydrogen again. (3) \u003cstrong\u003eDirect Methanol Fuel Cells (DMFC)\u003c\/strong\u003e: Pt-Ru is the only practical catalyst for DMFC anodes. Methanol oxidation inherently produces CO as an intermediate; without Ru, a methanol fuel cell would stop working within seconds.\u003c\/p\u003e\n\u003cp\u003eIn electrolyzers, Pt-Ru has a very specific \"reverse\" role compared to its fuel cell application. (1) \u003cstrong\u003eCathode (HER)\u003c\/strong\u003e: While Pt\/C is the standard for the Hydrogen Evolution Reaction, Pt-Ru is sometimes used in systems where the water source might have organic impurities or where the system needs to be reversible (a \"Unitized Regenerative Fuel Cell\"). (2) \u003cstrong\u003eAnode (OER)\u003c\/strong\u003e: Pt-Ru is rarely used as a pure alloy here. In the highly oxidative environment of the electrolyzer anode, both Pt and Ru metal can dissolve. However, Ruthenium Oxide (RuO2) mixed with Iridium Oxide is a common anode catalyst because it is one of the most active materials for splitting water, though it is less stable than pure Iridium.\u003c\/p\u003e\n\u003ctable style=\"width: 132.133%;
