NOVELTY - Hydrogen generation device (100) comprises: a draft tube (110), where a wall of the draft tube has many openings; many containing grooves (120a-e), disposed below the draft tube and respectively aligned with the openings, where each of the containing grooves contains a solid fuel; many water absorbing structures, disposed in the containing grooves; many capillary structures (140), alternatively disposed on an internal wall of the draft tube; and a water supply device (150), disposed at one end of the draft tube, where the water supply device is supplies a liquid fuel into the draft tube.    USE - The hydrogen generation device is useful in fuel cell (claimed) for an electronic device (e.g. a notebook computer or a cell phone) or a transportation vehicle (e.g. a car or a boat).    ADVANTAGE - The hydrogen generation device provides the reaction between a solid fuel and water in multiple stages. The capillary structure disposed between the two adjacent openings buffers the running liquid fuel so that the liquid fuel is prevented from entering another containing groove before it has completely reacted with the solid fuel in the current containing groove.    DETAILED DESCRIPTION - Hydrogen generation device (100) comprises: a draft tube (110), where a wall of the draft tube has many openings; many containing grooves (120a-e), disposed below the draft tube and respectively aligned with the openings, where each of the containing grooves is capable of containing a solid fuel; many water absorbing structures, disposed in the containing grooves, where each of the water absorbing structures is located between the corresponding opening and the corresponding solid fuel; many capillary structures (140), alternatively disposed on an internal wall of the draft tube, where each of the capillary structures is located between the two adjacent openings; and a water supply device (150), disposed at one end of the draft tube, where the water supply device is capable of supplying a liquid fuel into the draft tube, and the liquid fuel is capable of sequentially entering the containing grooves through the openings to sequentially react with the solid fuels and produce hydrogen. An INDEPENDENT CLAIM is also included for a fuel cell comprising: the hydrogen generation device; a fuel cell stack; and a guiding structure, connected between the hydrogen generation device and the fuel cell stack, where the guiding structure is capable of guiding the hydrogen produced by a reaction between the solid fuels and the liquid fuel to the fuel cell stack.
