In this case, even if the oxide film on the surface is scraped off and the surface of metallic aluminum is brought into contact with water, an oxide film is immediately formed on the surface of aluminum and the reaction does not proceed at room temperature. Thus, when aluminum is impregnated with a metal such as indium, gallium, or an alloy thereof to form an aluminum alloy, the metal aluminum in the alloy can react with water in the same manner as atomic aluminum. Although the principle is unknown, it is thought that metals such as indium have a large diffusion coefficient in aluminum and a large atomic radius, so that water enters the diffused path and the reaction with aluminum occurs continuously.

(Example 1) Hydrogen gas was generated through the steps shown in FIG. First, one end of a rod-shaped pure aluminum is shaved, a fresh aluminum surface is exposed, and the exposed surface is immersed in a molten indium gallium solution (30 ° C.). To prepare three types of indium gallium-impregnated aluminum alloys. For each of the alloys, strips were scraped from the indium gallium impregnated portion at one end and each chip was immediately placed in water. All three types of chips reacted with water to produce white aluminum hydroxide and gas. When this gas was collected and brought close to the fire, it reacted with oxygen to form water, so it was confirmed that the gas was hydrogen gas.
The amount of hydrogen gas generated increased as the impregnation amount of the indium gallium alloy increased. (Example 2) 0.27 g / minute of the 3% by weight indium gallium-impregnated aluminum alloy chip obtained in Example 1 was placed in water contained in a container. The reaction occurred, and aluminum hydroxide and hydrogen gas were continuously produced. During this reaction, water is circulated through a circulation path provided outside the container, and a by-product such as aluminum hydroxide generated in the reaction is removed by a filtration means provided in the circulation path. I did it. The amount of hydrogen gas generated was about 220 cc / min. The hydrogen gas generated in this manner was supplied to a known air-hydrogen fuel cell through a hydrogen gas outlet provided in the container to generate power. The power supplied to this generator was 10 W / h.
