Triggering interfacial activity of the traditional La0.5Sr0.5MnO3 cathode with Co-doping for proton-conducting solid oxide fuel cells

Doping the Co element into the traditional La 0.5 Sr 0.5 MnO 3− δ cathode material triggers the activity of the cathode/electrolyte interface in the composite cathode, leading to impressively high cell performance for proton-conducting solid oxide fuel cells.
