Portable water-using H2 production materials converted from waste aluminum

ABSTRACTThis 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 H2 production performances of waste aluminum H2 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/H2 conversion and a stable H2 flow rate for practical fuel cell electricity generation. In addition, the recycling of activation agents and Al(OH)3 can be realized.
