NOVELTY - A hydrogen generator (100) comprises a plasma reactor (110); a hydrogen storage medium (140); and an electrochemical hydrogen pump (150). The plasma reactor produces hydrogen ions by chemically activating a reactive gas containing a gas of a hydrogen atom-containing material, using a plasma discharge. The hydrogen storage medium stores the hydrogen ions produced by the plasma reactor. The electrochemical hydrogen pump generates hydrogen by pumping out the hydrogen ions from the hydrogen storage medium.    USE - As a hydrogen generator for generating hydrogen from a reactive gas containing a gas of a hydrogen atom-containing material (e.g. water, hydrocarbon, and organic material containing an alcohol group); useful in an electrically-driven system (claimed) such as an electric vehicle; useful for supplying hydrogen as a fuel in electric vehicles.    ADVANTAGE - The hydrogen generator generates hydrogen using plasma activation and electrochemical hydrogen pump. The hydrogen generator can activate the reactive gas using a microplasma at atmospheric pressure without the platinum-based catalyst used in the conventional electrolysis; and can obtain pure hydrogen by preventing transport of unnecessary gas (e.g. sulfur dioxide gas) from the reactive gas to the cathode, using the hydrogen storage medium. The hydrogen generator can rapidly pump out the hydrogen produced by the plasma reaction, using the electrochemical hydrogen pump. The hydrogen generator operates at a wide temperature range of 100-800 degrees C; generates hydrogen with half the power consumed in the electrolysis of pure water; and economically generates hydrogen, without use of the expensive platinum-based catalyst, and with low energy consumption.    DETAILED DESCRIPTION - A hydrogen generator (100) comprises a plasma reactor (110); a hydrogen storage medium (140); and an electrochemical hydrogen pump (150). The plasma reactor produces hydrogen ions by chemically activating a reactive gas containing a gas of a hydrogen atom-containing material, using a plasma discharge. The hydrogen storage medium stores the hydrogen ions produced by the plasma reactor. The electrochemical hydrogen pump generates hydrogen by pumping out the hydrogen ions from the hydrogen storage medium. The reactive gas further comprises sulfur dioxide, or at least one inert gas. The plasma reactor comprises a porous body having pores through which gas can pass; and a discharge generating unit that initiates a plasma discharge when the reactive gas flows through the pores. The discharge generating unit includes two electrodes disposed on both sides of the porous body. The hydrogen storage medium is a hydrogen storage metal layer disposed between the porous body and one of the two electrodes. The electrochemical hydrogen pump comprises a hydrogen ion conducting membrane; electrodes disposed on both sides of the hydrogen ion conducting membrane; and a power source for applying a voltage to the electrodes. The discharge generating unit is preferably configured into a dielectric barrier discharge system, a capillary discharge system, a micro-hollow cathode discharge system, a fine mesh electrode discharge system or a corona electrode discharge system.
