摘要
Zirconia-based electrolyte is considered to be the most reliable candidate as oxide-ion electrolyte for oxygen sensor, oxygen pump, and solid-oxide fuel cell. The electrical property and stability of zirconia-based electrolyte depend strongly on dopant type and concentration. In this review, phase diagrams, electrical properties, and the latest developments of zirconia-based electrolyte with different dopant are discussed. The methods used to increase oxide-ion conductivity and decrease the electronic conductivity of stabilized zirconia are also discussed.
