PROBLEM TO BE SOLVED: To provide a hydrogen occlusion alloy container wherein the filling factor of a hydrogen occlusion alloy can be increased without causing the deformation of the container. SOLUTION: In a cylindrical container body 1 in which the hydrogen occlusion alloy 10 is stored, a plurality of pipes 2, 3 in which the hydrogen occlusion alloy 10 is stored is stored along a container cylindrical direction. The pipes are each formed of a material having a yield stressσ<SB>ys</SB>of 200 MPa or more and a pipe strength (2(t/D)σ<SB>ys</SB>) of 5-15.5 MPa, desirably, where t is a pipe thickness (mm) and D is a pipe outer diameter (mm). As the deformation of the container remains suppressed, the filling factor of the hydrogen occlusion alloy can be increased to improve the volume efficiency by 15% or more. An alloy moving space is narrowed by the pipes, whereby the alloy is hardly moved in the vertical direction with vibration to suppress local deformation of the alloy. COPYRIGHT: (C)2008,JPO&INPIT
