<p class="PaperAbstract">Five La<sub>1-x</sub>Sr<sub>x</sub>MnO<sub>3+</sub><sub>d</sub>-based perovskites (x = 0, 0.05, 0.15, 0.25 and 0.50) were synthesized and investigated by powder XRD, dilatometry and electrochemical impedance spectroscopy measurements and cone-shaped electrode techniques. The thermal expansion coefficient increased with increasing strontium content. It was shown that the total polarization resistance was the lowest for the intermediate compound, La<sub>0.95</sub>Sr<sub>0.05</sub>MnO<sub>3+</sub><sub>d</sub>. Two arcs were found in the impedance spectra. These arcs were attributed to two one-electron processes. The results indicate that either Mn(III) is the catalytically active species or that the redox capacity is important for the activity of the compounds towards the reduction of oxygen in a solid oxide fuel cell. At higher temperatures, the oxide ionic conductivity may also play a role.</p>
