摘要	The occurrence of the incomplete capacitive semi-circle in the high frequency region of electrochemical impedance spectra was studied using thin electrolyte layer-covered two-electrode system. Thin electrolyte layer was made by evenly depositing NaCl particles onto the electrode surface and subsequently exposing to humid pure air with relative humidity of 84% and 25 degrees C. The incomplete capacitive semi-circle in the high frequency region was observed in low NaCl deposition density and in longer exposure duration of high NaCl deposition density. The occurrence of this incomplete capacitive semi-circle is decided by the nonuniformity of the current distribution on the electrode surface.; The occurrence of the incomplete capacitive semi-circle in the high frequency region of electrochemical impedance spectra was studied using thin electrolyte layer-covered two-electrode system.
