Abstract

The effect of uniform magnetic fields on hydrogen evolution reaction during metal deposition and water electrolysis was investigated by means of electrochemical techniques coupled with in-situ microscopic observation, velocity measurements and numeric simulation. The desorption of hydrogen bubbles is enhanced in applied magnetic fields independent on their orientation relative to electrode surface. The origin of this effect is attributed to Lorentz force driven convection generated by the applied magnetic field.

Keywords: two-phase flow; electrolysis; Lorentz force
