{"product_id":"cltsofecpcebzcy","title":"BZCY (BaZr0.7Ce0.2Y0.1O3-δ) Powder as Proton-Conducting Electrolyte for Low Temperature SOFC\/SOEC, 50 g\/bottle, CLTSOFECPCEBZCY","description":"\u003cp\u003eIn both Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC), BZCY (Barium Zirconate Cerate Yttrate)—typically formulated as BaZr0.1Ce0.7Y0.2O(3-x), is the leading Proton-Conducting Electrolyte. While traditional SOFCs (like YSZ) rely on the movement of heavy oxygen ions (O^{2-}), BZCY allows for the transport of small, highly mobile Protons (H+). This fundamental shift in charge carrier enables efficient operation at significantly lower temperatures (400°C–600°C).\u003c\/p\u003e\n\u003cp\u003eUsing protons instead of oxygen ions provides three transformative benefits for fuel cell and electrolysis technology: (1) \u003cstrong\u003eLower Activation Energy\u003c\/strong\u003e: Protons are the smallest possible ions. Because of their size, they \"hop\" through the crystal lattice with much less resistance than large oxygen ions, allowing for high power densities at intermediate temperatures. (2) \u003cstrong\u003eFuel Side Product Generation (SOFC)\u003c\/strong\u003e: In a proton-conducting SOFC (PC-SOFC), water is formed at the cathode (air side) rather than the anode. This prevents the fuel (hydrogen) from being diluted by water vapor, maintaining a high Nernst potential throughout the cell. (3) \u003cstrong\u003eDirect Pressurized Hydrogen (SOEC)\u003c\/strong\u003e: In electrolysis mode (SOEC), pure hydrogen is produced on the cathode side, while steam is fed to the anode. This simplifies the separation process and allows for the production of dry, high-purity hydrogen.\u003c\/p\u003e\n\u003cp\u003eBZCY is a solid solution of Barium Cerate (BaCeO3) and Barium Zirconate (BaZrO3): (1) \u003cstrong\u003eBarium Cerate (C)\u003c\/strong\u003e: Provides exceptionally high proton conductivity but is chemically unstable; it reacts with CO2 to form BaCO3, causing the cell to crumble. (2) \u003cstrong\u003eBarium Zirconate (Z)\u003c\/strong\u003e: Is extremely stable against CO2 and moisture but has very poor conductivity due to high grain-boundary resistance. (3) \u003cstrong\u003eHybrid (BZCY)\u003c\/strong\u003e: By combining them, BZCY achieves a \"sweet spot\"—it retains the high conductivity of the cerate while the zirconate fraction provides the chemical robustness needed to survive in real-world environments containing CO2.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eCLTSOFECPCEBZCY (C-LTSOFEC-PCE-BZCY)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e≥99.5%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003eBaZr\u003c\/span\u003e\u003csub\u003e0.7\u003c\/sub\u003e\u003cspan\u003eCe\u003c\/span\u003e\u003csub\u003e0.2\u003c\/sub\u003e\u003cspan\u003eY\u003c\/span\u003e\u003csub\u003e0.1\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3-δ\u003c\/sub\u003e\u003csub\u003e\u003c\/sub\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eSurface Area \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e15-30 m2\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e50 g\/bottle (other grades, such as 100 g, and 500 g or larger can be supplied upon request)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/iopscience.iop.org\/article\/10.1149\/2.0891805jes\/meta\"\u003eT.
