Abstract

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.

混沌动态磁场对水电解制氢的影响

绿色水电解获得的绿色氢是一种很有前途的可持续能源载体。然而，包括电催化剂材料在内的许多技术负担仍然存在。本研究探索了通过磁场暴露提高氢产量的新范例。磁场辅助电解在水电解制氢方面已显示出良好的改进前景。然而，一些技术需要专门的纳米结构设计，而直接磁场暴露的效率无法提高。本研究旨在设计一种电解系统，以改善磁场辅助电解系统的制氢效果。在电解槽周围粘贴抗磁性的驱动石电气石，形成混沌磁场。混沌磁场改善了静态磁场和动态磁场的暴露，但在高速动态磁场中更有效。磁场反射阻碍了氢键的重组和内聚，降低了电离能。磁场减缓氢氧根离子的运动，使更多的空间可用于氢氧根和电子的相互作用。因此，混沌电动势和DMF辅助电解通过水性质和离子转移控制提高了产氢率。
