Product Description

Intermediate Temperature Electrolyte Gadolinium Doped Cerium Oxide Powder

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.
