NOVELTY - A movable hydrogen generator with water-decomposable aluminum comprises hydrogen part and hot water supply part, including barrel (1), heating water pipe (2), insulating layer (3), barrel cover (4), hydrogen outlet interface (5), thermometer (6), hydrogen tube (8), pressure meter with electric contact (9), condensation filter (10), hydrogen tube (11), electric valve (13), hydrogen tube (14), constant-voltage hydrogen supply device (15), electric upper limit controller (16), electric lower limit controller (17), electric valve (18), hydrogen tube (19) and electric valve (20).    USE - The movable hydrogen generator with water-decomposable aluminum is useful for vehicles.    ADVANTAGE - The movable hydrogen generator with water-decomposable aluminum is simply structured and convenient to implement. The water-decomposable aluminum generates hydrogen and aluminum oxide during reaction at 60-95 degrees C, aluminum oxide is electrolytically reduced into aluminum that is used to generate the water-decomposable aluminum for circulation. The mass ratio between the hydrogen generation barrel and its hydrogen yield is about 20:1, which is about 1/4 of the mass ratio between hydrogen storage metal tank and its hydrogen reserves. The used working substances are non-toxic, harmless, flavorless, convenient and safe to use, and they are cheaper than gasoline.
