摘要
铝氢化钠(NaAlH_4) 在加入掺杂剂时能在低于100℃下可逆吸/放大量氢气 (目前氢的质量分数可达 4 .5%), 且价廉易得, 非常适用于作车用氢燃料电池上的储氢材料. 本文介绍了NaAlH_4储氢的基本原理、国外NaAlH_4储氢的研究进展. 并根据目前的研究现状提出了为提高可逆储氢质量分数, 加快吸/放氢速率所需进一步开展的工作.
The catalyzed sodium alanate (NaAlH_4) has been proposed as a reversible hydrogen storage material for fuel cell vehicle applications, because it has high hydrogen storage capacity (currently^4.5 mass%) at temperatures lower than 100℃ and is industrially available with low price. In this paper, the principle of hydrogen storage of NaAlH_4 and the progress in study of hydrogen storage properties of NaAlH_4 are introduced. And further studies to improve the reversible hydrogen storage capacity and hydrogen absorption and desorption rates are also proposed.
