Multiphase Flow Behavior and Electrolytic Characteristics in Alkaline Water Electrolysis with Magnetic Field

Abstract

Alkaline water electrolysis with magnetic field is a method for increasing the efficiency of hydrogen production through the electrolysis of alkaline water solutions. In the author’s research group, experiments and simulations were conducted to elucidate the multiphase flow behavior and electrolytic efficiency in alkaline water electrolysis with magnetic field. It was demonstrated that the electrolytic efficiency can be improved by changing the bubble motion, even with electrodes that are operable with permanent magnets (without the need for magnet power) and easily scalable, and with a weak magnetic field applied vertically.
