摘要：

The impedance of model platinum mesh electrode in contact with a doped zirconium-dioxide-based single-crystal electrolyte is studied by impedance spectroscopy under constant-current polarization. The electrode is distinguished for its readily determinable geometrical characteristics of the metal/electrolyte interface, in particular, the length of the triple-phase boundary and the electrode contact area. Three different orientations of the electrolyte face are studied. The impedance dispersion is discussed in terms of the electrode prehistory, orientation, and potential.
