Using electrochemical impedance spectroscopy (EIS), the polarization resistance (comprised of high frequency (HF) and low frequency (LF) features) of Ni-CZO symmetrical cells (Ni-CZO/YSZ/Ni-CZO) has been studied. The LF arc was almost negligible at all the operating temperatures in wet condition, and the HF arc linearly increased with time at 800 degrees C only in dry condition. The EIS response in dry and wet H-2 conditions clearly exhibited that water vapor enhanced the dissociative adsorption and surface diffusion of hydrogen and achieved stable electrochemical performance at 3PB on the Ni-CZO cermet.
