An innovative approach to design SOFC air electrode materials: high entropy La_1−xSr_x(Co,Cr,Fe,Mn,Ni)O_3−δ(<i>x</i>= 0, 0.1, 0.2, 0.3) perovskites synthesized by the sol–gel method

Abstract

For the first time, the high entropy perovskites from La_1−xSr<italic>x</italic>(Co,Cr,Fe,Mn,Ni)O₃₋<italic>δ</italic>(<italic>x</italic>= 0, 0.1, 0.2, 0.3, 0.4 and 0.5) series are documented to possess attractive properties as a candidate air electrode material for Solid Oxide Fuel Cells (SOFCs).
