Nano-galvanic aluminum based powder for hydrogen fuel invented by U.S. Army

Aluminum based nano-galvenic alloy refers to a class of nano-structured metal powders that produce spontaneous and rapidly hydrogen gas upon contact with water or any liquid containing water as a result of galvanic metal microstructure. It serves as a method of hydrogen production that can occur at room temperature rapidly without the help of chemicals, catalysts or externally supplied energy.

In the early 2010s, the U.S. investigated a new nano-structured aluminum alloy intended for structural material application. An aluminum-based nano-galvanic alloy was invented by researchers from the Army's Research Laboratory (ARL), the armor of the ARL and the Metals branch of the Materials Research Directorate (WMRD).During metallographic polishing for microhardness experiments, they found that the aluminum was disappearing when it came in contact with water and soon realized that it was producing hydrogen gas in the process.US Army Research Laboratory Specialist Polishing a newly engineered aluminum nano-powder saw an unexpected result: it started to produce hydrogen. Hydrogen, the highest element in the universe, is likely to power fuel cells and provide energy to future soldiers. Fuel cells produce electricity in a peaceful, efficient and without pollution. One kilogram of aluminum powder can produce 220 kilowatts of power in just three minutes.
