Abstract

Electrochemical Cells In article number 2304059, Sun-Ju Song, Chan-Woo Lee,WooChul Jung, Kang Taek Lee, and co-workers unveil the role of bimetal-doped BaCoO3−𝛿 (BCO) for highly active oxygen electrodes of protonic ceramic electrochemical cells. Through bimetal doping, the hexagonal structure of BCO is transformed into a cubic perovskite, leading to improved transport of all charge carriers (H+/O2−/e−).
