The discharge characteristics of MLNi_3.5MnCO_0.4Al_0.1(ML=mixed rare earths rich in lanthanum) hydrogen storage electrode were studied in the KOH solution of different concentration. The discharge capacity, fast discharge ability, selfdischarge rate of MH electrode were found to be improved by increasing the electrolyte concentration. The linear relationship between I_p and v^1/2 values obtained from cyclic voltammetry curves indicated that the reactions at the electrode were controlled by diffusion process.
- metal hydride electrode,
