In this study, experiments on the hydrogen production by wet grinding of aluminum through planetary ball mill were carried out with 100 alumina balls. Fine grinding speed and time in this work were fixed at 200 rpm and 1 hour, respectively. 280 ml of hydrogen gas was generated through the wet grinding with 3 g of aluminum powder in 100 ml of water. It is considered that surface temperature of aluminum increases from attrition and percussion with alumina medium, and water reacts with the surface of aluminum whose surface temperature reaches more than 100 degree to generate hydrogen gas. 280 ml of hydrogen could be obtained for 1 hour by electric power from window power generator with window speed of 5.27 m/s. Comparing former hydrogen generation method with water electrolysis (electric power : 3 W, generation time : 18.7 minutes, volume of hydrogen : 280 ml), it is found that 0.380 g of CO_2 could be reduced.

采用100个氧化铝球进行了行星式球磨机湿法磨铝制氢实验。本工作中的细磨速度和时间分别固定为200 rpm和1小时。通过在100 ml水中用3 g铝粉进行湿磨，产生280 ml氢气。认为铝的表面温度因与氧化铝介质的摩擦和撞击而升高，水与表面温度达到100 ℃以上的铝表面反应生成氢气。在窗口速度为5.27 m/s的情况下，通过来自窗口发电机的电力可以获得280 ml氢气1小时。与水电解制氢（电功率3 W，产氢时间18.7min，氢气体积280 ml）相比，可减少0.380gCO_2。
