Method for generating hydrogen gas utilizing activated aluminum fine particles

摘要

By activating aluminum fine particles obtained by milling aluminum alloy in water, reactivity of the aluminum fine Particles at low temperature is improved. The activation comprises a thermal shock treatment wherein the aluminum fine particles are repeatedly heated and cooled down rapidly, and subsequently these activated aluminum fine particles are stored in a refrigerator. By reaction between the activated aluminum fine particles and water molecules, a large amount of hydrogen gas can be generated at room temperature, therefore hydrogen gas or fuel for a portable-type fuel cells can be produced in large quantities at room temperature in a short period of time.
