PROBLEM TO BE SOLVED: To provide a hydrogen storage device and a hydrogen storage method capable of using a practicable and a lightweight hydrogen storage cartridge, even if using a hydrogen storage material requiring high pressure when storing hydrogen. SOLUTION: This hydrogen storage device stores the hydrogen in the hydrogen storage cartridge 1 filled with the hydrogen storage material capable of storing the hydrogen by pressure, and has a pressure vessel 2 endurable against hydrogen filling pressure, the hydrogen storage cartridge stored in its pressure vessel, a pipe 3 introducing the hydrogen into its hydrogen storage cartridge, and a pipe 14 introducing gas into a clearance between the pressure vessel and the hydrogen storage cartridge, and has a mechanism for controlling a pressure difference between the internal pressure and the external pressure of the hydrogen storage cartridge.
