Nickel-rare earth hydrogen storage alloy (Ni-AB_5) composite electrodes were prepared by the electrodeposition technique, and their electrocatalytic characteristics for hydrogen evolution reaction (HER) in 28% KOH solution were investigated by steady-state polarization curves and electrochemical impedance spectroscopy (EIS).

The preparation of surface coating containing NiMo and rare earth hydrogen storage alloy on Ni substrate by alloy electrodeposition and composite coating technique carried out for hydrogen evolution cathodes in alkaline media.

The market and application,varieties and quality,production capacity and output,production process and equipment and raw materials of RE hydrogen storage alloy powders in China are described,and discussed.
