Abstract
In order to achieve optimal weight and volume of a hydrogen storage apparatus, there is provided a method of charging hydrogen to a hydrogen storage apparatus. The hydrogen storage apparatus 1 includes a hydrogen storage means accommodating a hydrogen occlusive alloy (MH tank assembly) 3, and a hydrogen tank (high-pressure hydrogen tank) 2 that is provided separately from the hydrogen storage means 3 and stores hydrogen in gaseous form. Hydrogen is filled so that a pressure in the hydrogen tank is higher than that in the hydrogen storage means. A decompressing means (charger regulator) 6 is provided for reducing a pressure of hydrogen fed to the hydrogen storage apparatus 1 to maintain the pressure in a predetermined pressure range. The hydrogen storage apparatus 1 may include more than one of the hydrogen occlusive alloy tank (MH tank) 31.
