| Description |
Solid-oxide fuel cells (SOFCs) can be used for clean, efficient and environment-friendly energy conversion with a variety of
fuels at high temperature (1273 K). The high temperature operation accelerates unwanted reactions and creates materials
challenges; so, intermediate-temperature SOFCs (IT-SOFCs) have been developed. Reduction of the operating temperature
(between 873-1073 K) requires solid electrolyte materials with higher conductivities. In this study, partially substituted ceria as
solid electrolyte is experimented systematically for use in solid oxide fuel cells operating below 1073 K (intermediate temperature
range). Nine compositions namely, CeO2, Ce0.95Gd0.05O2-δ (CGO9505), Ce0.90Gd0.10O2-δ (CGO9010), Ce0.85Gd0.15O2-δ (CGO8515),
Ce0.80Gd0.20O2-δ (CGO8020), Ce0.95Sm0.05O2-δ (SDC9505), Ce0.90Sm0.10O2-δ (SDC9010), Ce0.85Sm0.15O2-δ (SDC8515) and
Ce0.80Sm0.20O2-δ (SDC8020) were synthesized by Glycine Nitrate (GN) combustion technique and investigated. The physical
properties and the other relevant features of the data obtained are analyzed with a view to use these alternate electrolyte materials
in IT-SOFC.
