中文摘要：

考察了铝粒径、碱浓度、温度、球磨时间以及添加剂等因素对铝粉水解性能的影响，并通过水解实验和扫描电镜分析。实验结果表明。铝粒径的减小、碱浓度和温度的增加、球磨时间的延长以及添加剂的加入提高了铝粉在碱溶液的水解速率。例如：铝-10％（质量分数）盐混合物球磨后，铝粉的水解速率由球磨前的136mL/（min·g）增加到604mL/（min·g）。采用铝-碱溶液制氢，可为燃料电池提供不含有毒气体的氢气，实现现场制氢、供氢，有效解决氢气储存问题。

英文摘要：

The effects of aluminum powder size, alkaline solution density, temperature, milling time, and the additives on the hydrolysis properties of aluminum were studied through the hydrolysis experiments and SEM analysis. The results showed that the smaller aluminum powder size, the higher alkaline solution density and temperature, the longer milling time and the additives could improve the hydrolysis rate of aluminum powder. For examples, the milled A1-10% NaCI mixture had the hydrolysis rate of 604 mL/（min .g）, higher than 136 mL/（min-g） of unmilled aluminum powders at the same conditions. The hydrogen generation from the Al-NaOH reaction could supply the hydrogen gas excluding the poisonous gas for the fuel cell and solve the hydrogen storage problem by realizing when and where the hydrogen was generated.
