Abstract

Due to hydrogen’s functional versatility within a diverse range of energy and industrial applications, renewable hydrogen presents an excellent opportunity to enhance the sustainability of anthropogenic activities. This research demonstrates the capacity magnetic fields have to increase the efficiency of hydrogen production and exhibits the influences magnetic fields have on water’s molecular dynamics. The results indicate that a magnetic field can increase electrolysis efficiency by up to 7.6 % when applied with a bar magnet and up to 21 % when applied with a Helmholtz coil, and can also facilitate higher hydrogen production rates with higher power inputs without compromising the efficiency. The results also indicate that enhanced electrolyser function is due to the magnetic field increasing water’s molecular energy. This study highlights the potential that the application of magnetic fields has to increase electrolyser efficiency while forming a foundation for future research into optimising water’s molecular dynamics to enhance electrolysis efficiency.

水电解过程中磁场对电化学和分子动力学的影响

由于氢在各种能源和工业应用中的功能多功能性，可再生氢为增强人类活动的可持续性提供了极好的机会。本研究论证了磁场提高制氢效率的能力，并展示了磁场对水分子动力学的影响。结果表明，磁场可以使条形磁铁的电解效率提高7.6%，亥姆霍兹线圈的电解效率提高21%，并且可以在不影响效率的情况下，在更高的功率输入下促进更高的产氢率。结果还表明，增强的电解槽功能是由于磁场增加了水的分子能。这项研究强调了应用磁场提高电解槽效率的潜力，同时为未来优化水分子动力学以提高电解效率的研究奠定了基础。
