电池电极反应的新应用：分步法电解制氢气
|
Abstract:
摘要 可再生能源与电解水制氢技术的结合是实现可持续制氢的最佳途径. 然而，传统电解水技术中解决氢-氧同时、同步、同地产生的问题必须依赖于膜分离技术，大幅限制了氢-氧分离和氢气异地运输的灵活性，并阻碍了可再生能源(如风能、太阳能)与电解水技术的直接结合. 针对上述问题，作者课题组在近期提出了基于电池电极反应的分步法电解水制氢技术，即通过电池电极的可逆电化学反应将现有电解水过程拆分为制氢和制氧分立步骤，实现在无膜条件下氢气和氧气的分时、分地交替制备，提升了电解水制氢的灵活性，促进了可再生能源向氢能的直接转化. 本文将介绍这一新技术的研究进展，并分析这一技术的优点和面临的挑战
