Ceria Dopant for Zirconia SOFC Electrolyte
CAS Number: 1306-38-3
Cerium dioxide (CeO2) is used as a dopant in gadolinia-doped ceria (GDC) and samaria-doped ceria (SDC) electrolytes for intermediate-temperature solid oxide fuel cells (IT-SOFC). CeO2 also serves as a phase stabilizer in zirconia, a catalytic promoter in automotive catalysts, and a polishing compound for glass and optical components.
