Abstract: A novel process to obtain H2 from flat plate aluminum corrosion in aqueous acid solutions is described. A modified traditional shrinking core model has been developed to analyze kinetics behavior by including the effect of growing and textural changes of hydroxide layer during reaction. Modified model is fitted to experimental data. Initial diffusion coefficient, magnitude of the change in its value and the ratio of volume of the produced shell to volume of consumed core during reaction were determined by parameters obtained from fitting the proposed model to experimental data.
