{"product_id":"cecearuo","title":"Amorphous Ruthenium Oxide (RuOx) Coated Electrode for Electrolyzer, CECEARuO","description":"\u003cp\u003eRuthenium Oxide (RuOx) coated metal Felt (or carbon paper) is the \"gold standard\" anode for Proton Exchange Membrane (PEM) water electrolyzers. Unlike alkaline systems that can use nickel, PEM systems operate at a very low pH (acidic) and high potentials, where almost all other metals—except titanium and noble metals—would rapidly corrode.\u003c\/p\u003e\n\u003cp\u003eIn PEM systems, the environment is highly acidic (pH \u0026lt; 2). Most transition metals (like the FeCoNi we discussed earlier) would dissolve instantly. (1) \u003cstrong\u003eThe RuOx Advantage\u003c\/strong\u003e: It has the lowest overpotential of any catalyst in acid, meaning it requires the least amount of electricity to split water. (2) \u003cstrong\u003eThe Stability Trade-off\u003c\/strong\u003e: Pure RuOx is unstable at the high potentials (\u0026gt; 1.45 V) required for water splitting. It tends to oxidize into RuO4, which is volatile and soluble, leading to \"catalyst leaching\". (3) \u003cstrong\u003eIndustrial Solution\u003c\/strong\u003e: Most commercial PEM anodes use a Mixed Metal Oxide (MMO) coating, blending RuO2 with IrO2. The Iridium acts as a \"sacrificial\" or stabilizing agent to protect the Ruthenium.\u003c\/p\u003e\n\u003cp\u003eIn alkaline systems (20–30% KOH), RuOx is technically superior in performance but rarely used. (1) \u003cstrong\u003eEconomics\u003c\/strong\u003e: Since Ni-Fe based catalysts (like FeCoNi) can achieve very high efficiency in alkaline media for a fraction of the cost, RuOx is usually deemed \"over-engineered\" for standard AWE. (2) \u003cstrong\u003eApplication\u003c\/strong\u003e: It is only used in specialized alkaline cells where extremely high current densities or specific ultrapure hydrogen requirements justify the cost of noble metals.\u003c\/p\u003e\n\u003ctable style=\"width: 101.819%; height: 651.25px;\" width=\"100%\"\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\u003eCECEARuO\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 55.2px;\"\u003e\u003cem\u003eElectrode Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 55.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eRuOx active material was chemically plated on the Ti felt or carbon paper. \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\u003eTi Felt Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 197.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 250 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePorosity: 50-60 %\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFiber diameter: 25-50 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFiber length: 35 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSpecial coating (eg: Pt, Au) on the substrate can be additionally supplied upon request. \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\u003eSS Felt Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 620 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePorosity: 50-60 %\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 30.2013%; height: 71.2px;\"\u003e\u003cem\u003eTi Mesh Substrate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4101%; height: 71.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThickness: 200 um\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMesh pore: 1mm*2 mm\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\u003eL 5cm * W 5cm \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 RuOx 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:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/aenm.202503199\"\u003eR.
