要約(英語): Three-dimensional large scale magnetohydrodynamic, two-phase flow, and electrochemical reaction coupling numerical simulations of alkaline water electrolysis with magnetic field were conducted to elucidate the bubble-bubble interaction and the influence of that on the overpotential. Numerical results shown that the magnetic field enhances the coalesce of bubbles and the bubble size was increased with the increase in the magnetic flux density. Moreover, the magnetic field suppressed the cell overpotential by suppressing the anode overpotential and ohmic overpotential. This is because, KOH concentration around the anode is increased by mixing of the electrolyte, and the reduction of the shielding effect by coalescing of the bubbles.
