The average value of hydrogen diffusion coefficient in metal hydride (MH) electrode was measured by constant current discharge method. The relationship between hydrogen diffusion coefficient and state of charge (SOC) was determined by potentiostatic method. According to the MH electrode model, the fast charging performance of MH electrode can be improved by increasing hydrogen diffusion coefficient or decreasing the particle size of hydrogen storage alloy. The time when the surface hydrogen atom concentration on the MH electrode reaches maximum value under different initial states of charge and charge rates also can be calculated.
