Experimental study of the operating parameters of an aluminum water hydrogen generator

The paper presents a fundamentally new design for a hydrogen generator. Hydrogen is released during the reaction of activated aluminum and water. Bismuth, tin, and calcium oxide were used as the activating additives. The hydrogen generator results in an Al oxidation reaction at a temperature of $100$–$350^{\circ}$C and a pressure of about $4$ atm. An average hydrogen production rate of $30$ mL/(s g) was achieved with a hydrogen yield of $95$–$99\%$ of the theoretically possible value. In continuous generation mode, the average productivity of the hydrogen generator was $\sim1.5$ kW $(140$ mL $\rm H_2$/s$)$.
