Key Points

The aim is to evaluate the effectiveness of a cobalt-free perovskite cathode for oxygen reduction at intermediate temperatures.
Evaluated La 0.8 Sr 0.2 FeO 3-δ (LSF) as the cathode material for solid oxide fuel cells.
Assessed performance focused on oxygen reduction reaction kinetics at intermediate temperatures.
LSF demonstrated enhanced performance due to increased oxygen vacancies, improving oxygen reduction kinetics.
Specific metrics on performance improvement metrics not detailed in abstract.

Implication

Investigates efficient oxygen reduction in cathodes for solid oxide fuel cells, suggesting improved performance.

Abstract

Perovskite-type La 0.8 Sr 0.2 FeO 3-δ (LSF) is a competitive cobalt-free cathode candidate in solid oxide fuel cells (SOFCs), but its sluggish oxygen reduction reaction (ORR) kinetics at intermediate temperatures severely hinders practical application....
