气泡如何影响氢气生产：新发现对所有电解工艺具有重要意义How Gas Bubbles Influence Hydrogen Production: New Findings Relevant to All Electrolysis Processes
➀ 由德国亥姆霍兹德累斯顿罗森多夫研究中心（HZDR）领导的德荷研究团队发现，电解槽中的氢气泡含有电解液微滴，首次揭示了气泡内部流动动态；
➁ 研究表明，微小气泡合并时形成电解液微射流并产生液滴云，这些液滴通过改变电极接触和延迟气泡脱离降低效率；
➂ 发表于《自然·通讯》的成果为提升电解槽效率提供了新思路，后续研究由德国联邦教研部（BMBF）和荷兰科研组织（NWO）资助，以解决技术难题。
➀ A German-Dutch research team led by Helmholtz-Zentrum Dresden-Rossendorf (HZDR) discovered that hydrogen bubbles in electrolyzers contain electrolyte microdroplets, revealing internal flow dynamics for the first time;
➁ The study identified that gas bubbles merge and create microjets of electrolyte, forming droplet clouds that reduce efficiency by altering electrode contact and delaying bubble detachment;
➂ Findings, published in Nature Communications, provide insights into improving electrolyzer efficiency, with ongoing research funded by BMBF and NWO to address technical challenges.
