Abstract铝是地壳中最富有的金属元素,理论上可100%重复利用。铝/水反应所提供的绿色能源——氢能,很有可能解决人类将面临的能源短缺和环境污染问题。本文介绍了铝/水反应可控制氢的原理、反应机理、制氢方法及制氢装置的最新研究进展,并讨论了研发中需解决的问题。铝/水反应制氢的关键在于破坏或抑制铝表面固有的或原位再生的致密钝化膜。该制氢系统的实际应用需具备快速的反应动力学,而制氢装置的设计应综合考虑反应热的利用、燃料电池产生的水循环利用、燃料盒和膜分离技术的应用,使用回收的废铝将降低其生产成本,实现铝基制氢系统的商业化应用。
Other AbstractAluminum is the most abundant crustal metallic element on the earth and 100% recycled in theory. Controlled hydrogen generation (HG) by reaction of aluminum with water could provide a renewable energy cycle to address the global energy problem. In this perspective, we present the state of art in the principle, mechanism, approaches, and hydrogen generator of HG from the reaction of aluminum with water, and further discuss some remaining problems in the development of aluminum-based HG system. The key to the HG by the reaction of aluminum with water is how to disrupt/inhibit a native/regeneration coherent and adherent passivation film of aluminum surface. The fast kinetics is desirable in developing the aluminum-based HG system for the practical application. The design of hydrogen generator should focus on the utilization of reaction heat to preheat fuel, the recycle of water from the fuel cell, the fuel cartridges and the process of separation by the membrane. The use of recycled scrap aluminum will provide a reasonable hydrogen cost, thus promoting its commercial applications.
