Abstract

See full text

A hydrogen storage method is provided which enables a hydrogen storage alloy to store hydrogen up to a maximum hydrogen storage amount thereof in excess of a generally known theoretical value. In a hydrogenation step, a hydrogen storage ratio calculated as an atomic weight ratio between hydrogen and the hydrogen storage alloy is obtained beforehand as a theoretical value, a pressure at which the hydrogen storage alloy stores hydrogen up to the theoretical value is set as a first pressure value, a pressure value ten or more times greater than the first pressure value is set as a second pressure value, and pressure is increased up to the second pressure value. In a dehydrogenation step, the pressure is decreased from the second pressure value to or below the first pressure value. The hydrogenation step and the dehydrogenation step are repeatedly executed.
