An important part of the hydrogen energy problems is the search of hydrogen sources for feeding hydrogen–air fuel cells. One of the most convenient methods for hydrogen generation is based on oxidation of aluminum by water. In this paper the method of aluminum activation based on the application of gallium alloys (gallams) is suggested.In this work the activated aluminum powders made of commercially available aluminum wires are investigated. The kinetic parameters of the reaction of activated aluminum with water (hydrogen generation rate and hydrogen yield) depending on the gallam’s amount and composition, powder particle sizes and reaction temperature are studied.
► The reactivity of activated aluminum wires with water. ► The influence of reaction parameters and alloy composition/amount on the reactivity. ► The addition of tin into gallam leads to increase of the hydrogen generation rate. ► The reduction of the cost of activated aluminum.
