NOVELTY - The canister (100) has a canister body (1) having a bottom end (11), an outlet (12) opposed to the bottom end, and an inner space (13), where the bottom end and the outlet are arranged along a long axis direction. A supporting plate (21) is accommodated within the inner space along the long axis direction. A compartment structure (4) comprises a set of compartments (42) defined by a set of partition plates (41), where the compartment structures and the supporting plate are alternately accommodated within the inner space. Each compartment stores a predetermined amount of gas storage material.    USE - Compartment structure integrated gas storage canister for storing a hydrogen-containing fuel e.g. hydrocarbon such as natural gas, methanol, ethanol, product from water hydrolysis, and marsh gas, that is utilized in a fuel cell.    ADVANTAGE - The canister allows conducting external heat uniformly to the compartments of all compartment structures during operation of a fuel cell system such that heat applied to inner and outer portions of the gas storage material are not distinguished during a heating stage so as to output released gas more uniformly and stably, thus enhancing operating efficacy of canister. The compartment structure is accommodated within a receptacle of a housing of the canister and the partition plate is effective to reinforce structural strength of the housing such that operation of the canister is more stable and working efficiency of the fuel cell system is enhanced so that a gas storage cartridge is modularized to facilitate production, assembly and application, and industrial utilization of the canister is enhanced.    DETAILED DESCRIPTION - The compartment structure is selected from a group consisting of a honeycomb-like compartment structure, rectangular compartment structure, square compartment structure, polygonal compartment structure, irregular shaped compartment structure and a circular compartment structure.
