Army researchers have developed a novel, structurally-stable, aluminum-based nanogalvanic alloy powder that, when combined with water or any water-based liquid, reacts to produce on-demand hydrogen for power generation at room temperature without chemicals, catalysts or externally supplied power. These patent-pending powders produce hydrogen at a rate that currently is one of the fastest reported for Al and water reactions without the need of hazardous and costly materials or additional processes. The reaction results in the production of hydrogen and heat with only inert residual materials; i.e., no toxic by-products. ARL has demonstrated that hydrolysis will occur with virtually any water containing liquid. It has long been known that aluminum (Al) reacts with water to produce hydrogen gas and aluminum oxide via a hydrolysis reaction. Aluminum metal oxidizes when in contact with water, rapidly producing a passivating oxide layer which prevents the hydrolysis reaction (H 2 ). Further, hydrolysis to […]
