This work proposes an empirical law correlating the La peak height ratio Lb2.15/La1 to Cr concentrations determined on Cr-doped LSM–YSZ samples characterized by EDXS. Calibration for the law was obtained by chemical analysis of dissolved cathodes. Quantification was confirmed by wavelength-dispersive X-ray spectroscopy.Energy dispersive X-ray spectroscopy (EDXS)PerovskiteSolid oxide fuel cell (SOFC)PerovskiteFuel Cell MaterialsSeparatortext::journal::journal article::research article
