Automated Hydrogen Generator

A demo model of an automated hydrogen generator is described. The power-independent generator ensures the on-site hydrogen production on demand. Hydrogen evolution occurs when the hydrogen-generating formulation prepared by mechanochemical activation of aluminum reacts with water. Bismuth, tin (Bi 3.3 wt %, Sn 1.4 wt %), and calcium oxide are used as activating additives. The mean rate of hydrogen revolution exceeds 30 mL s –1 g –1 , and the hydrogen yield is 95–99%. In the mode of continuous hydrogen generation, the mean productive capacity of the generator is about 150 mL s –1 (about 1.6 kW).
