A Comprehensive Multimodal Study of La0.45Sr0.45TiO3 Structure as Matrix for the Exsolution Process: From the Average to the Local Scale.
We report a comprehensive structural investigation of La0.45Sr0.45TiO3 (LSTO) as a ceramic matrix for exsolution-based fuel electrodes in solid oxide fuel cells and electrolyzers. Synchrotron radiation powder diffraction reveals an average cubic perovskite structure from room temperature to 900°C, even under the reduci...
