This study investigates the feasibility of using waste aluminum as a substitute to pure aluminum for preparing portable water-using hydrogen production materials by gas atomization process. The H-2 production performances of waste aluminum H-2 production materials in different reaction conditions considering reaction temperature, reaction aqueous solution and water adding method were investigated. The results show that such materials can achieve a high Al/H-2 conversion and a stable H-2 flow rate for practical fuel cell electricity generation. In addition, the recycling of activation agents and Al(OH)(3) can be realized.
