Abstract: 
The existence and role of platinum oxide in the solid state electrode system Pt(O₂)/yttria-stabilized
zirconia is discussed. Covering and porous model-type Pt film
electrodes on YSZ single crystals are investigated by cyclic
voltammetry, electrochemical impedance spectroscopy, and in situ
scanning photoelectron microscopy. The formation of Pt oxide and its
amount strongly depend on the experimental conditions, such as
temperature, oxygen partial pressure, and oxygen flux towards the
electrode during anodic polarization. Electrode activation and
deactivation processes can be explained by formation and decomposition
of Pt oxide, which is reducing or inhibiting the oxygen exchange rate.
