Improvement of oxygen reduction activity and stability on a perovskite oxide surface by electrochemical potential

Abstract The instability of the surface chemistry in transition metal oxide perovskites is the main factor hindering the long-term durability of oxygen electrodes in solid oxide electrochemical cells. The instability of surface chemistry is mainly due to the segregation of A-site dopants from the la...
