ALUMINUM ALLOY, HYDROGEN GAS GENERATION METHOD, HYDROGEN GAS GENERATOR, AND ELECTRIC GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide an easily obtainable raw material for hydrogen gas generator, a method for generating hydrogen gas of high purity easily and effectively, a simple and lightweight hydrogen gas generator therefor, and an electric generator taking advantage of this hydrogen generator. SOLUTION: This method for generating hydrogen gas comprises reacting an aluminum alloy for generating hydrogen gas with water, which consists of an aluminum base material including indium, gallium, or an alloy thereof of 15 wt.% or less against the aluminum base material. The hydrogen gas generator comprises a vessel containing the aluminum alloy and water, a water circulating path, and a means for removing by-products. The electric generator comprises combining the hydrogen gas generator and a fuel cell so as to use the generated hydrogen gas as a hydrogen source.
