Fuente: WIPO "tomato" The present invention is directed to a method of generating hydrogen. The method comprises the steps of: combining aluminum or an aluminum alloy with gallium or a gallium eutectic to form a compound; placing the compound in contact with a solution comprising an aliphatic diprotic or triprotic carboxylic acid to corrode the aluminum or aluminum alloy, and generating hydrogen and hydrolyzed aluminum as a byproduct; collecting the generated hydrogen; and recovering the solution for reuse. The present method is an environmentally sound, highly efficient method, which generates useful quantities of hydrogen in a scalable system.
