- •
Ln0.5Sr0·5Fe0·8Cu0·2O3−δ was studied as a cathode material for IT-SOFCs.
- •
Electrochemical properties of the perovskites were studied using GDC electrolyte.
- •
Ln0.5Sr0·5Fe0·8Cu0·2O3−δ was thermally and chemically compatible with GDC.
- •
Changing Ln from La to Pr to Nd decreased the ASR of the Ln0.5Sr0·5Fe0·8Cu0·2O3−δ.
- •
A peak power density of 944.5 mW cm−2 is obtained for the single cells at 800 °C.
