NOVELTY - A hydrogen supply system for safely storing hydrogen and capable of supplying hydrogen in gaseous form to a hydrogen-using device, includes a housing with a first partition, and an inner wall; hydrogen storage canister(s) which each accommodates a hydrogen storage alloy; a piping mechanism having two ends and an inlet/outlet port; and a control valve arranged on the piping mechanism.    USE - The hydrogen supply system for storing and supplying hydrogen in gaseous form to a hydrogen-using device, e.g. fuel cell, gas chromatography system, or fluorescence spectrometer.    ADVANTAGE - The hydrogen supply system stores hydrogen safely and supplies hydrogen in gaseous form to a hydrogen-using device. It is also portable.    DETAILED DESCRIPTION - A hydrogen supply system (1) for safely storing hydrogen and capable of supplying hydrogen in gaseous form to a hydrogen-using device, comprises a housing (12) having a first partition (122) and an inner wall (124). Hydrogen storage canister(s) (14) is provided. Each canister accommodates a hydrogen storage alloy. It is spaced from one another, and mounted onto the first partition of the housing, and has a respective opening exposed between the first partition and the inner wall of the housing. A piping mechanism is provided having two ends exposed outside the housing. The first end of the piping mechanism is sealingly connected to the opening of each hydrogen storage canister. An inlet/outlet port (16) is provided at the second end of the piping mechanism. A control valve (18) is arranged on the piping mechanism near the inlet/outlet port. When the system, with previously charged hydrogen in the hydrogen storage canister, connects with the hydrogen-using device, the system supplies hydrogen with a stable pressure at the inlet/ outlet port to the hydrogen-using device, and the pressure of the hydrogen supplied by the system is capable of being varied by adjusting the control valve.
