Generation of hydrogen by aluminium oxidation in aquaeous solutions at low temperatures

Oxidation of granulated non-activated aluminium (2.5 g of aluminium per 300 ml of solution) with hydrochloric acid solution in the presence of CuCl2 (2.5 g per 300 ml of solution) resulted in generation of more than 2000 ml of hydrogen during 300 min. For FeCl3 solution the total value of hydrogen obtained during 180 min was equal to 70 ml, it also has been observed partial freezing of this solution.
