<P>PROBLEM TO BE SOLVED: To provide a hydrogen supply apparatus which can generate hydrogen from water more efficiently than the conventional electrolysis, and also can generate hydrogen without requiring electric power if sunlight is present, and can be mounted even to vehicles such as automobiles, under such circumstances that, though hydrogen used as a fuel which replaces petroleum is developed as the fuel for an automobile, since risk in case of an accident is extremely high when a large quantity of hydrogen is loaded on a fuel tank, such an idea that hydrogen generated by electrolyzing water is used as a fuel is considered, but, in electrolysis for which electric power is used and potential is applied to electrodes, the efficiency of energy obtained by using the generated hydrogen as the fuel is low compared with the used electric power. <P>SOLUTION: The hydrogen supply apparatus for an internal combustion engine and a fuel cell is characterized in that light is emitted to a photocatalyst provided in an aqueous solution within a vessel or within a tube to generate hydrogen and oxygen, and the hydrogen or hydrogen and oxygen are supplied to an internal combustion engine and a fuel cell, wherein the photocatalytic action of decomposing water into hydrogen and oxygen by emitting light to the photocatalyst in the water is applied. <P>COPYRIGHT: (C)2011,JPO&INPIT |
