Gadolinium-doped ceria (GDC) (known alternatively as gadolinia-doped ceria, gadolinium-doped cerium oxide, cerium(IV) oxide, gadolinium-doped, and GCO, formula Gd:CeO2) is a ceramic electrolyte used in solid oxide fuel cells (SOFCs).
Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide.
TOB New Energy provides the 8YSZ(with 8 mol% Y2O3 Fully Stabilized ZrO2) and Scandia-Stabilized Zircoina(SSZ) electrolyte sheets for solid oxide fuel cells.
