摘要： Disclosed are a highly ionic conductive zirconia electrolyte and a high-efficiency solid oxide fuel cell using the same. The highly ionic conductive zirconia electrolyte is configured such that a scandia (Sc2O3) stabilized zirconia (ZrO2) electrolyte is simultaneously doped with cerium oxide (CeO2) and at least one oxide of gadolinium oxide (Gd2O3), samarium oxide (Sm2O3), and ytterbium oxide (Yb2O3) so that an ionic conductivity drop rate is mitigated.

摘要： Disclosed is a scandia-stabilized zirconia electrolyte for a solid oxide fuel cell, which is configured such that at least one oxide selected from among gadolinium oxide (Gd2O3) and samarium oxide (Sm2O3) is co-doped with ytterbium oxide (Yb2O3) to thus improve stability in a reducing atmosphere. The scandia-stabilized zirconia electrolyte of the invention can be stabilized into a cubic crystal structure at room temperature while retaining the inherently high oxygen ionic conductivity of a scandia-stabilized zirconia electrolyte (11ScSZ), and can also ensure stability in a reducing atmosphere by solving the problem with a conventional ceria (CeO2)-doped scandia-stabilized zirconia in which the ionic conductivity continuously deteriorates in a reducing atmosphere.
