Hydrogen marketplace is expected to grow exponentially, hydrogen is getting attention as a clean energy source that does not emit CO2. We are studying the hydrogen production method by reaction of water and aluminum powder. In this study, it was necessary to increase the rate of hydrogen production. Therefore, we investigated the time variation of the hydrogen production rate, which has not been done before. Al powder was stirred in water and hydrogen was extracted. Three types of powder were used in this experiment: Al powder, Al-5wt%Sn alloy powder, and mixture Al and Sn powder. The objective of this experiment is to determine the optimum conditions for increasing the hydrogen production rate. Hydrogen flow rates were found to temporarily exceed 0.1 ml/s. The powder that produced the most hydrogen was an Al-5wt%Sn alloy powder. By measuring the flow rate of hydrogen, it is possible to predict the mechanism of the reaction of Al powder and water.
