  • Doping the La 0.5 Sr 0.5 MnO 3− δ (LSM) cathode with the Co element allows the new material La 0.5 Sr 0.5 Mn 0.9 Co 0.1 O 3− δ (LSMCo) to show improved performance compared with the Co-free LSM for proton-conducting solid oxide fuel cells (H-SOFCs), demonstrated by both experiments and first-principles calculations. More importantly, doping Co into LSM triggers the activity of the cathode/electrolyte interface in the composite cathode, leading to an impressively high fuel cell performance of the cell using the LSMCo composite cathode and also revealing the importance of the interfacial design for the cathode of H-SOFCs. 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.
