Abstract: A hydrogen production method and hydrogen production system using the reaction of water and aluminum, the hydrogen production method and system being capable of continuously generating hydrogen for a long period of time without causing a decrease in the total amount of hydrogen generation. A hydrogen generation system according to one embodiment of the present invention includes aluminum sheet placed in a container and calcium hydroxide contained in the same container. In the hydrogen production system having the previously described configuration, water is poured in the container to dissolve the calcium hydroxide so that an aqueous solution is prepared, and the aluminum sheet is immersed in this aqueous solution. As a result, the hydrogen generation reaction begins, generating hydrogen gas. The amount, rate and duration of the generation of hydrogen gas can be controlled by adjusting the area and thickness of the aluminum sheet.

Abstract: Provided is a packaged hydrogen-generating agent, the hydrogen-generating reaction of which is highly stable and repeatable, and which preferably is resistant to influence from changes in the environmental temperature. Also provided are a method for manufacturing said package, and a hydrogen generation method. The packaged hydrogen-generating agent is provided with: a hydrogen-generating agent (1); a covering material (2) which encloses the hydrogen-generating agent (1) and allows deformation; and a water-absorbing body (3), part of which is in contact with the hydrogen-generating agent (1). The covering material (2) preferably covers at least the area around the contact part (3a) where the water-absorbing body (3) and the hydrogen-generating agent (1) are in contact, so as to create a firm attachment at the contact part (3a).
