Tracking the nanoparticle exsolution/reoxidation processes of Ni-doped SrTi 0.3 Fe 0.7 O 3− δ electrodes for intermediate temperature symmetric solid oxide fuel cells

In situ NAP-XPS and XAS are used to elucidate the mechanisms of the exsolution/reoxidation process in Sr 0.93 Ti 0.3 Fe 0.63 Ni 0.07 O 3− δ (STFN) perovskite, used as an electrode for intermediate temperature-SOFC.
