The present invention provides a hydrogen storage cartridge that not only is small and lightweight, but also allows storage and discharge of hydrogen at low pressure and normal temperature. Preferably, it is possible to effectively absorb the volume expansion accompanying atomization of a hydrogen storage alloy that occurs due to repeated storage and discharge of hydrogen, and therefore a hydrogen storage cartridge (A) is provided in which not only is deformation due to repeated use, and in particular irregular deformation, extremely unlikely, but also it is possible to effectively avoid hydrogen storage irregularities of the hydrogen storage alloy. The present invention is a hydrogen storage cartridge (A) used for storage of hydrogen contained in biomass thermal decomposition gas, wherein the material of the hydrogen storage cartridge (A) is pure titanium, and the hydrogen storage cartridge (A) includes in the interior space (1) thereof, as a hydrogen storage alloy, at least one hydrogen storage alloy selected from the group comprising lanthanum mischmetal/nickel, titanium/iron, calcium/nickel, and lanthanum/nickel. |
