ABSTRACT:
A fuel tank for a hydrogen vehicle in which a plurality of fuel cylinders are disposed and contained in a casing of the fuel tank for containing hydrogen storage alloy, the fuel cylinders are connected to a header mounted integrally with the casing for containing the fuel cylinders, a conduit for supplying engine exhaust gas is connected to the casing for externally heating the fuel cylinders in the casing. Further, a fuel supplying system which comprises supplying hydrogen gas from a fuel supply conduit connected to a header mounted integrally with the fuel tank, supplying the hydrogen gas from the openings of a plurality of fuel cylinders into the inner cylinder sections of the fuel cylinders to allow the hydrogen gas to be absorbed to hydrogen storage alloy of the respective fuel cylinders, supplying air or water from an engine exhaust gas passage of a fuel tank casing into the casing in case of supplying the hydrogen while cooling the fuel cylinders from the exterior, closing the fuel supply conduit of the header after filling the hydrogen gas of a predetermined amount, and then supplying the exhaust gas through the engine exhaust gas passage to externally heat the fuel cylinders in case of desorbing the hydrogen gas in the fuel tank. Thus, the fuel tank can desorb or absorb hydrogen under a relatively low pressure and can store the hydrogen in the amount corresponding to the running distance of a gasoline vehicle in a compact structure.
