Investigating oxygen reduction pathways on pristine SOFC cathode surfaces by in situ PLD impedance spectroscopy.

ABSTRACT: The oxygen exchange reaction mechanism on truly pristine surfaces of SOFC cathode materials (La_0.6Sr_0.4CoO_3-δ = LSC, La_0.6Sr_0.4FeO_3-δ = LSF, (La_0.6Sr_0.4)_0.98Pt_0.02FeO_3-δ = Pt:LSF, SrTi_0.3Fe_0.7O_3-δ = STF, Pr_0.1Ce_0.9O_2-δ = PCO and La_0.6Sr_0.4MnO_3-δ = LSM) was investigated employing in situ impedance spectroscopy during pulsed laser deposition (i-PLD) over a wide temperature and p(O₂) range. Besides demonstrating the often astonishing catalytic capabilities of the materials, it is possible to discuss the oxygen
