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).
LSCF may be used as the cathode in solid oxide fuel cells (SOFCs). LSCF oxygen electrodes can be used in the fabrication of high-performance solid oxide fuel cells (SOFCs).
