Decreasing the dimensionality of the LaxSr1–xTiO family structure from 3D to 2D by increasing the La content greatly enhances the electrochemical performance of the material as an SOFC anode. This is attested to by the strong decrease in the polarization resistance values deduced from the complex impedance spectra (Nyquist plot) recorded at 900 °C in H2/H2O(3%) on a symmetrical cell.
