Sr-doped LaMnO3, as one of the most successful cathodes for solid oxide fuel cells (SOFCs), can effectively function at high temperatures. However, its cathode kinetics considerably decreases with decreasing temperature, rendering it unsuitable for SOFCs operating at intermediate temperatures. In this study, La0.5Sr0.5MnO3-delta(LSM) is coated with TiO2 to create the LSM + TiO2 cathode. TiO2 is shown to modify the electronic structure at the LSM/TiO2 interface, allowing for charge accumulation for the O atoms at the interface. The activated O atoms enhance the formation of oxygen vacancies, wh...
