Lanthanum strontium cobalt oxide

Uses

SOFCs containing LSC-82 cathodes show good performances with doped ceria electrolytes compared to yttria stabilized zirconia electrolytes.

General Description

LSC-82 is a promising cathode material for Solid Oxide Fuel Cells with a pervoskite type structure.
LSC-82 has the unique ability to reduce itself reversibly at moderate partial pressures of oxygen, thus producing large numbers of oxygen ion vacancies. The ion vacancies allow a number of events to take place, such as;

• ease the transport of oxygen ion and cause oxygen surface exchange,
• raise mechanical stress by causing volume expansion of the lattice.

Influence of change in temperature on the properties of LSC-82 has been reported in detail. Effect of temperature on magnetic susceptibility has also been reported.
