The reaction of aluminum with water has the potential for on demand hydrogen generation. Conventional aluminum powders, however, react with water slowly due to a highly protective oxide layer on the particle surface. The present paper investigates the preparation of an activated aluminum powder from aluminum foil that is widely available as scrap and waste. The obtained results demonstrate that a highly reactive, fine aluminum powder can be obtained from aluminum foil by high-energy ball milling with sodium chloride. The obtained powder readily reacts with hot water, releasing hydrogen. The process includes the induction period, the middle stage where the reaction rate is the highest, and the final (saturation) stage. The effective activation energy of the reaction rate at the middle stage is in a good agreement with the literature data for Al-H2O reaction.

One method of producing on-demand hydrogen for fuel cells is through the use of aluminum which reacts with water under certain conditions to produce hydrogen. This process can be used for applications as small as portable handheld devices, onboard generation for vehicles, or as large as a hydrogen refueling center. However, the utilization of aluminum for generating on-demand hydrogen is critically dependent on the control of the rate of hydrogen generation from the reaction. Experiments with micron and nano-sized aluminum powder are described in this work and the effects of particle size, reagent quantities, temperature and solution concentration on the hydrogen generation rate and total yield are analyzed and quantified. Regression models are developed and yield and rate predictions are confirmed. In general, aluminum nanoparticles are found to have poorer hydrogen yields, but marginally faster reaction rates as compared to micron particles.
