NOVELTY - Hybrid-type hydrogen generator comprises an electrolyzer (200) for producing hydrogen and oxygen gases to electrolyze water supplied from a first water supply unit (100), a fossil fuel gasifier supplied with oxygen gas from electrolyzer, a fuel supply unit (400) to produces vaporized hydrocarbon fuel, a gas generator provided with a gas distribution portion (300) for recovering oxygen gas supplied to the fossil fuel gasifier, a mixer (500) producing mixing gas from vaporized hydrocarbon fuel from fuel supply unit and oxygen gas from gas distribution portion.    USE - The generator is useful for producing hydrogen gas (claimed).    ADVANTAGE - The generator has high production efficiency, and reduces size of the device for rapid production of hydrogen gas.    DETAILED DESCRIPTION - Hybrid-type hydrogen generator comprises a first water supply unit, an electrolyzer for producing hydrogen and oxygen gases to electrolyze the water supplied from the first water supply unit, a fossil fuel gasifier supplied with oxygen gas supplied from the electrolyzer, a fuel supply unit to produces vaporized hydrocarbon fuel, a gas generator provided with a gas distribution portion for recovering the oxygen gas supplied to the fossil fuel gasifier, a mixer producing the mixing gas from the vaporized hydrocarbon fuel which is supplied from the fuel supply part and the oxygen gas supplied from the gas distribution portion, a synthetic gas generating unit producing synthetic gas by processing the mixed gas, which is supplied from the mixer in a plasma state, and a hydrogen separator for separating the purified hydrogen gas in the synthetic gas, which supplied from the synthetic gas generating unit. An INDEPENDENT CLAIM is also included for producing hydrogen gas using the hybrid-type hydrogen generator, comprising (a) electrolyzing water to produce hydrogen gas and oxygen gas, (b) vaporizing the hydrocarbon fuel, (c) producing the synthetic gas by processing the produced oxygen gas and the produced vaporized hydrocarbon fuel in the plasma state, and separating the hydrogen gas from the synthetic gas produced in the step (c).    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the hybrid-type hydrogen generator.
