{"product_id":"ceceiro2","title":"Iridium Oxide (IrO2) Coated Electrode for Electrolzyer, CECEIrO2","description":"\u003cp\u003eIridium-coated titanium\/nickel felt\/mesh\/foam is a high-performance porous transport layer (PTL) or gas diffusion layer (GDL) specifically optimized for the oxygen evolution reaction (OER) on the anode side of PEM water electrolyzers. While it is also applicable to fuel cells and regenerative electrochemical systems, its primary industrial role is in electrolyzers because it can withstand the harsh, acidic, and highly oxidative environments that would immediately destroy standard carbon-based materials.\u003c\/p\u003e\n\u003cp\u003eThe key features of the iridium coated titanium\/nickel felt\/mesh\/foam are: (1) \u003cstrong\u003eCorrosion Resistance\u003c\/strong\u003e: Titanium is used because carbon-based GDLs oxidize to CO2 or carbonate ions under high anodic potentials (1.8 V to 2.0 V). The iridium coating further protects the titanium from surface passivation (forming an insulating TiO2 layer), which would otherwise increase interfacial resistance and lower efficiency. (2) \u003cstrong\u003eReduced Resistance\u003c\/strong\u003e: The uniform iridium layer reduces the overall ohmic resistance at the PTL\/catalyst interface, potentially enabling higher cell voltages and improving long-term durability. (3) \u003cstrong\u003eOptimized Mass Transport\u003c\/strong\u003e: Titanium felt features a unique three-dimensional fiber network with high porosity (typically 60–70%), which facilitates efficient fluid and gas transport. (4) \u003cstrong\u003eCatalytic Activity\u003c\/strong\u003e: Iridium oxides (IrO2) are recognized as some of the few materials that provide both high catalytic activity for the OER and reasonable resistance to dissolution in acidic electrolytes.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 457.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCECEIrO2 (C-E-CE-IrO2)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 67.2px;\"\u003e\u003cem\u003eElectrode Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/echemsupplies.com\/products\/cefceairo2?variant=48048901619942\u0026amp;_pos=2\u0026amp;_sid=9e805ec1e\u0026amp;_ss=r\"\u003eIrO2 nanoparticles\u003c\/a\u003e (Accelerate) were sprayed coated on various PTL substrate\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe default binder\/ionomer is Nafion.
