Description

General description

Samarium doped ceria may be used as an electrolyte in solid oxide fuel cells (SOFCs). Electrical conductivity as a function of temperature of doped ceria was investigated in a study. Relation of dopant type, oxygen vacancy ordering and ionic conductivity was investigated by transmission electron microscopy and electron energy loss spectroscopy.

Packaging

10 g in glass bottle

Application

Electrolyte material for solid state oxide fuel cells (SOFC).
