Abstract

Oxygen potential distribution in a ZrO₂-based solid electrolyte in the vicinity of a dense film platinum electrode under a current flow was investigated by using in-situ micro x-ray absorption spectroscopy. The oxide ion conductor (Y₂O₃)_0.08(ZrO₂) _0.92 doped with 2.5 mo1% of Mn₂O₃, in which the valence state of manganese ions could be used as an indicator for evaluating the oxygen potential, was chosen as a model electrolyte. As results, a drastic drop of oxygen potential was apparently observed near the triple phase boundary. The proposed method was found to be principally applicable for the direct observation of the oxygen potential distribution in an oxide ion conductor under a current flow.
