贮氢电极电化学阻抗谱及其数学模型
摘要:
从分析贮氢电极的放电过程着手，建立了具有明显物理意义贮氢电极电化学阻抗谱（EIS）的数学模型．以该数学模型为基础，讨论了与电极材料性质和电极荷电状态相联系的一些参数，如：双电层电容Cd1、原子氢扩散系数D、吸附平衡常数Keq、吸附反应速率常数和放电深度（DOD）对贮氢电极电化学阻抗谱（EIS）的影响，此外，该数学模型较好地解释了实验结果，这也证明了模型的正确性.

Electrochemical Impedance Spectroscopy(EIS) of Metal Hydride Electrode and its Mathematical Model
Abstract:
A mathematical model for electrochemical impedance spectroscopy (EIS) of metal hydride electrode bas been proposed. This model predicts how some parameters such as the capacitance of electrical double layer Cd1, the diffusion coefficient D, the equilibrium constant Keq and the rate constant of adsorption reaction, the depth of discharge (DOD) affect the electrochemical impedance spectroscopy (EIS) of metal hydride electrode. Moreover, this model is consistent with experimental results.
