Abstract

Sr_0.95Nb_0.1Co_0.9O_3−δ (P4/mmm crystal structure), displaying a large JT distortion combined with charge-ordering of cobalt, shows improved ORR activity at low temperature, whereas Sr_0.98Nb_0.1Co_0.9O_3−δ (P4mm crystal structure), with a slight JT distortion, shows diminished performance.
