Pr and Mn infiltrated oxide nanoparticles are confirmed as excellent candidates for boosting the performance of standard lanthanum strontium manganese oxygen electrodes.

In this work, solid solutions of La 0.7 Sr 0.3 Mn 0.9 5Fe 0.05 O 3-δ with different oxygen content were obtained by the solid-phase reactions technique. Based on investigation dynamics changes in index (3 – δ) during heating samples, formation a stressed state their grains as result annealing was established. This results decrease mobility vacancies reduction cations according to 4+ + e → 3+ sc...
