XIAMENIntermediate Temperature Electrolyte Gadolinium Doped Cerium Oxide Powder
SPECIFICATIONS （TOB-GDC-10）
Gadolinium doped ceria (GDC) may be used as an intermediate temperature electrolyte for solid oxide fuel cells (SOFCs) at elevated temperatures. Cerium(IV) oxide-gadolinium doped powder (10 mol% gadolinium doped) (GDC-10) is an electrolytic material with high oxygen-ion conductivity, which operates at low temperatures. It can be prepared by a variety of methods such as sol-gel, wet chemical process, co-precipitation, hydrothermal and other combustion routes. Gadolinium doped ceria may be prepared by cation complexation sol-gel technique. Higher oxygen ion conductivity of GDC over zirconia-based materials makes it a preferable choice for some components of SOFCs.
