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.
