A new cathode with Ti2 Ni alloys and Ni/Mo electrocatalyst has been developed for alkaline water electrolysis. The characterization for hydrogen evolution reaction (HER)is carried out in a 30 wt% potassium hydroxide (KOH) solution. The cathode shows a low hydrogen overpotential(η=60 mV at 70℃ in 30 wt% KOH) and ezcellent stability under conditions of continuous electrolysis and intermittent electrolysis with power interruption .
