Abstract
A pressure container 1 composed of a reinforcing layer 2 and a liner layer 3, with a hydrogen charging pressure of 30 MPa or higher; and a hydrogen absorbing material and a carrier for holding said hydrogen absorbing material (hydrogen absorbing material portion 4) contained in the pressure container 1 are included, and a volume fraction X of the hydrogen absorbing material with αm≧100 kg/m3 with respect to an internal volume of the pressure container 1 is 5(%)≦X≦20(%), where αm denotes a maximum hydrogen absorption amount per unit volume of the hydrogen absorbing material (kg/m3); X=100 ·Vm/Vi (%); Vi is an internal volume of the pressure container (L); and Vm is a volume of the hydrogen absorbing material in the pressure container (L).
