Hydrogen generator, and hydrogen generation container

A hydrogen generation container comprising:

• a bar-shaped case body including a hollow space defined therein for containing magnesium particles or aluminum powder, and a plurality of windows disposed on an upper surface or a lower surface of the case body at predetermined intervals in a longitudinal direction of the case body for allowing the hollow space to communicate with an outside of the case body;
• an air-permeable and water-impermeable material for covering the plurality of windows;
• an injection opening disposed at one end of the case body for injecting water into the hollow space of the case body to react with the magnesium particles or aluminum powder, thereby generating hydrogen;
• and
• a sealer configured for closing the injection opening,
• wherein the generated hydrogen flows out through the air-permeable and water permeable material, and the injected water is prevented from flowing out through the air-permeable and water permeable material.
