Abstract
The constant potential discharge technique, constant current discharge technique and electrochemical impedance spectroscopy were employed to determine the hydrogen diffusion coefficient in a metal hydride electrode of MlNi3.65Co0.75Mn0.4Al0.2 alloy with various depth of discharge (DOD) at room temperature and with a specific DOD at various temperatures. The results were compared and the advantages and disadvantages of these techniques were also discussed.
