{"product_id":"citsofecceniogdc","title":"NiO\/GDC (Gadolinia-Doped Ceria) Composite Powder as Cermet Electrode for Intermediate Temperature SOFC\/SOEC, 100 g\/bottle, CITSOFECCENiOGDC","description":"\u003cp\u003eIn Solid Oxide Fuel Cell (SOFC) and Electrolysis Cell (SOEC) applications, NiO\/GDC (Gadolinia-Doped Ceria) composite powder is the primary choice for Intermediate Temperature (IT) operation, typically between 500°C and 700°C.While NiO\/YSZ is the \"gold standard\" for high-temperature cells (\u0026gt;800°C$), GDC is preferred for lower temperatures because its ionic conductivity at 600°C is comparable to that of YSZ at 800°C.\u003c\/p\u003e\n\u003cp\u003eThe switch from YSZ to GDC in the nickel cermet provides several electrochemical and chemical benefits: (1) \u003cstrong\u003eMixed Ionic-Electronic Conductivity (MIEC)\u003c\/strong\u003e: Unlike YSZ, which is a pure ionic conductor, GDC becomes a mixed conductor in the reducing environment of the anode. This allows the electrochemical reaction to occur on the entire surface of the GDC grains, rather than being restricted to the narrow Triple Phase Boundary (TPB) where Ni, YSZ, and gas meet. (2) \u003cstrong\u003eCoking \u0026amp; Sulfur Resistance\u003c\/strong\u003e: GDC has a higher \"oxygen storage capacity.\" This allows it to chemically \"burn off\" carbon deposits (coke) and resist sulfur poisoning much more effectively than YSZ, making it ideal for running on hydrocarbons (methane, ethanol) or biogas. (3) \u003cstrong\u003eHigher Catalytic Activity\u003c\/strong\u003e: Ni-GDC exhibits faster charge-transfer kinetics, which significantly reduces the activation polarization (voltage loss) at lower temperatures.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 112.999px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.6875px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 40.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 40.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCITSOFECCENiOGDC (C-ITSOEFC-CE-NiOGDC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003eInitial: 60 wt% NiO +40 wt% \u003cspan\u003eGd\u003c\/span\u003e\u003csub\u003e0.1\u003c\/sub\u003e\u003cspan\u003eCe\u003c\/span\u003e\u003csub\u003e0.9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e2-x\u003c\/sub\u003e\u003c\/p\u003e\n\u003cp\u003eAfter Reduction: 48.9 vol% NiO + 51.1 vol% \u003cspan\u003eGd\u003c\/span\u003e\u003csub\u003e0.1\u003c\/sub\u003e\u003cspan\u003eCe\u003c\/span\u003e\u003csub\u003e0.9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e2-x\u003c\/sub\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eBET Surface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e4-8 m2\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e100 g\/bottle (other grades, such as 500 g, 1000 g, or higher can be supplied upon request)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FCM","offers":[{"title":"Default Title","offer_id":47455110627558,"sku":"CITSOFECCENiOGDC","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CITSOFECCENiOGDC_main.png?v=1773619407","url":"https:\/\/echemsupplies.com\/products\/citsofecceniogdc","provider":"EChem Supplies","version":"1.0","type":"link"}
