Provided is a method for hydrogen occlusion that is for causing a hydrogen-storage alloy to occlude hydrogen up to a maximum hydrogen occlusion amount possessed by the hydrogen-storage alloy which exceeds a generally known theoretical value. The method for hydrogen occlusion comprises repeating a hydrogenation step and a dehydrogenation step. In the hydrogenation step, a hydrogen occlusion ratio, which is calculated as atomic-weight ratio between the hydrogen-storage alloy and hydrogen, is determined beforehand as a theoretical value, the pressure at which the hydrogen-storage alloy has occluded hydrogen up to the theoretical value is set as a first pressure value, a pressure value which is at least 10 times the first pressure value is set as a second pressure value, and the pressure is elevated to the second pressure value. In the dehydrogenation step, the pressure is lowered from the second pressure value to or below the first pressure value. |
