The impact of chaotic dynamic magnetic field on hydrogen production through water electrolysis

• Diamagnetic Dravite Tourmaline stone induces chaotic magnetic field. • Chaotic magnetic field (CMF) causes static magnetic field (SMF) unstable. • CMF more effective to Enhance Dynamic magnetic field (DMF) electrolysis. • CMF in high rotational speed DMF effectively alter hydrogen production. • CMF and DMF control water properties and ion transfer during electrolysis. Green hydrogen obtained from green water electrolysis is a promising sustainable energy carrier. However, many technical burdens still presents including the electrocatalyst material. This study explores new paradigm to improve hydrogen yields via magnetic field exposure. Magnetic field assisted electrolysis has shown promising improvements of hydrogen production from water electrolysis. However, some techniques require specialized nanostructure design while the efficiency of direct magnetic field exposure cannot be improved. This study aims to design an electrolysis system to improve hydrogen production of magnetic field assisted electrolysis system. The diamagnetic dravite tourmaline stone was sticked around the electrolyzer to create chaotic magnetic field. The chaotic magnetic field improves both static (SMF) and dynamic magnetic field (DMF) exposure but more effective in high rotational speed DMF. The magnetic field reflection prevents hydrogen bond reformation and cohesion which lowers ionization energy. The magnetic field slows OH- ion movement so that more rooms are available for H + and electrons interaction. Therefore, the chaotic EMF and DMF assisted electrolysis improves hydrogen production through water properties and ion transfer control.
