Description

WO 2004/041715 PCT/KR2003/002395 APPARATUS FOR GENERATING HYDROGEN GAS Technical Field 5 The present invention relates to an apparatus for generating hydrogen gas; and, more particularly, to an apparatus for generating hydrogen gas from water. Description of the Prior Art 10 Hydrogen gas which can be produced from basic industrial resources has a great potential to be widely applied in various fields of current energy system such as commonly distributed fuel, hydrogen-fueled cars and air 15 planes, fuel cells and nuclear fusion energy. if hydrogen is chemically combusted under appropriately controlled conditions, hydrogen can be used as an energy source like commonly supplied urban gas. Hydrogen and oxygen are combusted in a volume ratio of 2 to 20 1 to produce water in vapor state. At this time, about 28,620 kcal per kilogram is generated, and this amount of calorie is sufficient to raise a temperature of about 0.3 tons of water at about 0 oC to about 100 oC. Also, hydrogen is capable of generating electric 25 energy through a fuel cell as well as of generating enormous amounts of energy like a hydrogen bomb through a nuclear fusion reaction. Hydrogen can be directly combusted to produce energy and can also be a convenient energy source such as a fuel cell. Furthermore, hydrogen 30 is a source of generating almost infinite amounts of water and is recycled as water, thereby being a renewable energy source. Although hydrogen exists with a traceable amount of about 0.1 parts per million (ppm) in atmosphere, hydrogen 35 exists in various types of compounds with almost infinite amounts. Among various types of compounds, water (H 2 0) is the most commonly found compound containing hydrogen. 1 WO 2004/041715 PCT/KR2003/002395 Also, crude oil and natural gas composed of diverse carbon compounds containing carbon and hydrogen are good sources of hydrogen. There are two typical methods of generating hydrogen 5 gas. One method is to obtain hydrogen gas by electrolyzing water. The other method is to obtain hydrogen gas from carbon compounds of natural gas or crude oil by a thermal decomposition. More particularly, hydrogen and oxygen should be 10 separated from a water molecule composed of one oxygen atom and two hydrogen atoms in order to obtain hydrogen gas from water. For the electrolysis of water, about 4 grams of hydrogen can be obtained from about 36 grams of water. Theoretically, the electrolysis of water requires about 15 1.23 voltages. However, a higher voltage is required in actual practice due to an internal resistance of a device. Since the electricity is an energy source that can be directly applicable in industries, the use of electricity to obtain hydrogen gas, which is, in turn, used again as an 20 energy source, decreases efficiency on usage of the energy. Therefore, the use of electricity is limitedly applicable by using redundant electricity such as electricity generated at night to electrolyze water, store hydrogen from the electrolysis through an appropriate method and 25 regenerate electricity by using a fuel cell. For another method for obtaining hydrogen gas, hydrocarbon such as naphtha obtained by purifying natural gas or crude oil gets to react with vapor at a high temperature. However, the natural gas and crude oil are 30 highly effective but non-renewable energy sources. Thus, there is a limitation in obtaining hydrogen gas with use of such energy sources. 35 Summary of the Invention It is, therefore, an object of the present invention 2 WO 2004/041715 PCT/KR2003/002395 to provide an apparatus for generating hydrogen gas from water without using a non-renewable energy source such as fossil fuel containing hydrocarbons. It is another object of the present invention to 5 provide an apparatus for generating lots of hydrogen gas with use of a small amount of energy without employing electrolysis. In accordance with an aspect of the present invention, there is provided an apparatus for generating hydrogen gas, 10 including: an operation fluid supply unit for supplying an operation fluid which is water after highly purifying water and pressurizing the water with a predetermined pressure; a body having a passage where the operation fluid flows; a dielectric implant for passing the operation fluid through 15 a passage slot and generating an electric impulse with a high potential by a cavitation emission, the dielectric implant implanted in the passage of the body; a separation unit for separating ions of the operation fluid based on electric polarities of the ions by supplying a magnetic 20 field to a flow of the operation fluid ionized by the electric impulse; and a collecting unit for separately collecting the ions separated by the separation unit and generating hydrogen gas. The body is formed with a dielectric material having a 25 tolerance to a cavitation emission phenomenon generated inside of the body. That is, the body is made of one of ceramics, ruby and sapphire. The dielectric implant is formed in the passage of the body. Herein, the dielectric implant has one or more than one passage slot allowing the 30 operation fluid to flow. Inner walls of the passage slot and portions around the inner walls are made of a dielectric material easily resulting in the cavitation emission phenomenon, e.g. asbestos. Also, an expansion unit of which cross-sectional area is expanded is formed at 35 an outlet side of the passage slot. Particularly, the expansion unit serves to abruptly decrease a pressure of the operation fluid. 3 WO 2004/041715 PCT/KR2003/002395 The separation unit is connected with the body and includes a channel with a predetermined length and separation channels. Herein, magnetic bodies are formed at lateral sides of the channel such that a North pole of a 5 group of the magnetic bodies and a South pole of another group of the magnetic bodies face with each other. The separation channels are formed at a rear end of the channel and serves to separate the operation fluid into two paths. At this time, the operation fluid is separated 10 perpendicular to a magnetic field provided by the magnetic bodies. The collecting unit is an enclosed tank. At a bottom part of the collecting unit, there is an input pipe to which the operation fluid separately containing lots of 15 hydrogen ions and hydrogen oxide ions is supplied. The input pipe is connected with each rear end of the separation channels. Also, the tank includes a catalytic plate contacting the operation fluid at a wide surface area region and having a specific structure allowing gas 20 generated from a contact surface of the catalytic plate to rise and a membrane for selectively passing hydrogen gas generated at the catalytic plate. Herein, the membrane is formed at an upper part of the tank. The upper part of the tank includes a first 25 discharging pipe being formed at an upper part of the membrane and being connected with a first hydrogen tank, a second discharging pipe being formed at a bottom part of the membrane and being connected with a second hydrogen tank and a third discharging pipe being formed at a height 30 around a top of the catalytic plate. Herein, the first discharging pipe discharges the hydrogen gas highly purified by passing through the membrane. The second discharging pipe discharges the hydrogen gas lowly purified by not passing through the membrane. The third discharging 35 pipe recollects water passing through the catalytic plate and sends the water back to the operation fluid supply unit. 4 WO 2004/041715 PCT/KR2003/002395 The first hydrogen tank stores the highly purified hydrogen gas, while the second hydrogen tank stores the lowly purified hydrogen gas containing oxygen or vapor. It is preferable to have a check valve at each inlet of the 5 first and the second hydrogen tanks to prevent an inversed flow of gas. The catalytic plate is preferably made of one of palladium and rhodium. The catalytic plate has a property of absorbing or permeating lots of hydrogen. The hydrogen 10 permeated from the catalytic plate can give rise to vigorous reduction reactions at a room temperature because of strong activity of the permeated hydrogen. Operations of the apparatus for generating hydrogen gas will be described in detail. 15 The apparatus for generating hydrogen gas first ionizes water, which is an operation fluid. A magnetic field is then supplied to a flow of the ionized operation fluid. The operation fluid containing lots of ions are separated based on their electric polarities by using the 20 Lorentz force generated by the magnetic field. At this time, the collecting unit is formed at each of two respective places at which the separated positively charged ions and negatively charged ions arrive to thereby generate hydrogen gas. 25 The operation fluid supply unit supplies highly purified water through purification steps. The water is pressurized with a predetermined uniform pressure by a pump allocated at an outlet side of the operation fluid supply unit and is subsequently supplied to an input pipe of the 30 body. At this time, a pulse generator is connected to a pipe at the outlet side to thereby provide a pulse with a predetermined frequency. The predetermined frequency is related to unique oscillation numbers of the passage slot of the dielectric implant generating the cavitation 35 emission phenomenon. The water flows into the passage of the body and rapidly passes through the passage slot of the dielectric 5 WO 2004/041715 PCT/KR2003/002395 implant. When the water passes through the expansion unit formed at the outlet side of the passage slot, the inside diameter of the expansion unit increases. This increased inside diameter decreases a pressure, thereby decreasing a 5 boiling point. Therefore, fine bubbles are created within the flow of the operation fluid, and these bubbles expand and eventually burst out. When these bubbles burst around an end part of the expansion unit formed at the outlet side of the passage 10 slot, a very high pressure wave is generated and affects the dielectric implant. At this time, the generated pressure wave nearly equals to an atmospheric pressure of about 10,000 bars. Because of the high pressure wave, there are created 15 fine cracks on the inner walls of the passage slot of the dielectric implant. Electrons are emitted from the fine cracks due to a property of the material used in the inner walls, i.e., the property that easily resulting in the cavitation emission phenomenon. The emitted electrons are 20 dispersed within the operation fluid, thereby resulting in the Vavilov-Cheronkov effect. As the electrons having negative charges are emitted, the outlet side of the passage slot becomes positively charged. The inner walls and adjacent regions to the inner 25 walls can be charged with a high electric potential without causing electron discharge because of the above mentioned property. Electric shock generated by the high electric potential partially ionizes the water. The above described course of ionization can apply to 30 other dielectric fluids containing hydrogen such as mineral oil, kerosene and acetone. Therefore, it is possible to use these dielectric liquids containing hydrogen as the operation fluid. A magnetic field is supplied to the flow of the 35 operation fluid containing hydrogen ions and hydrogen oxide ions. As a result of the supplied magnetic field, the hydrogen and hydrogen oxide ions are affected by the 6 WO 2004/041715 PCT/KR2003/002395 Lorentz force in a perpendicular direction to the magnetic field, thereby being separated based on their electric polarities, i.e. positive charged ions and negatively charged ions. 5 The separated ions move towards each corresponding collecting unit. Within the collecting unit, which is an enclosed tank, the operation fluid separately containing the hydrogen ions and the hydrogen oxide ions contacts the catalytic plate, which in turn, absorbs highly reductive 10 hydrogen and discharges the hydrogen to thereby generate hydrogen gas. The generated hydrogen gas rises from each collecting unit and passes through the membrane to be stored in the first hydrogen tank. If the hydrogen gas does not pass 15 through the membrane, the hydrogen gas is stored in the second hydrogen tank.

The apparatus for generating hydrogen includes a body 10, a dielectric implant 20, a passage slot 21, a 20 separation unit 50 and collecting units 60. Particularly, the body 10 has a passage where operation fluid, i.e., water, can flow. The dielectric implant 20 is implanted within the body 10 and gets the operation fluid to pass through the passage slot 21. Also, the dielectric implant 25 20 generates an electric impulse with a high potential by a cavitation emission. The separation unit 50 supplies an electric field to a flow of the operation fluid which is ionized by an electric impulse and separates ions based on electric polarities of the ions. Each collecting unit 60 30 collects hydrogen ions separated by the supplied electric field and generates hydrogen gas. The separation unit 50 has a channel 51 where the ionized operation fluid flows, magnetic bodies 52 having a North (N) pole and a South pole (S) facing each other by 35 being disposed at lateral sides of the channel 51 and supplying a magnetic field to the channel 51 and a first and a second separation channel 53 separating a flow of the 8 WO 2004/041715 PCT/KR2003/002395 operation fluid into two separate streams by the magnetic field.

Especially, the first discharging pipe 64 discharges the hydrogen gas highly purified as passing through the membrane 63. The second discharging pipe 65 discharges the lowly purified hydrogen gas that cannot pass 25 through the membrane 63. The third discharging pipe 66 collects water which passed through the catalytic plate 62 and sending the water back to an operation fluid supply unit. A check valve 74 for preventing counter-flow of the 30 gas is formed at each inlet of the first hydrogen tank 71 and the second hydrogen tank 72. Fig. 2 is a perspective view showing a body structure of the apparatus for generating hydrogen gas in accordance with the preferred embodiment of the present invention. 35 The apparatus for generating hydrogen gas includes the body 10 formed in a pipe type or a channel type, a pipe 11 in an inlet side and another pipe 12 in an outlet side. 9 WO 2004/041715 PCT/KR2003/002395 Hereinafter, the pipe 11 in the inlet side and the pipe 12 in the outlet side are referred to as the inlet pipe and the outlet pipe. The body 10 serves to prevent the operation fluid from leaking by being assembled with the 5 inlet pipe 11, the outlet pipe 12, flanges 15 and volts 17. A connection unit of the flanges 15 can include a high pressure sealing member. Herein, the body 10 is made of a material having a high tolerance to a cavitation emission phenomenon. That 10 is, a material that does not easily emit electrons during the cavitation emission is used. For instance, ceramics, sapphire and ruby are preferable examples of such material for the body 10. Also, silicon carbide (SIC), which is a sintering agent, is an exemplary material for the ceramics. 15 Fig. 3 is a cross-sectional view showing an internal structure of the body of the apparatus for generating hydrogen gas in accordance with the preferred embodiment of the present invention. The apparatus for generating hydrogen gas includes the body 10 having a passage where 20 the operation fluid can flow and the dielectric implant 20 being implanted inside of the body 10 and having at least more than one the passage slot 21 in which the operation fluid passes through to generate an electric impulse with a high potential by the cavitation emission phenomenon. 25 Also, there is an expansion unit 22 of which inside diameter is expanded at an outlet 23 side of the passage slot 21. The operation fluid, i.e., water, is ionized by the electrical impulse. The dielectric implant 20 is made of one of sapphire 30 and ruby. Also, inner walls of the passage slot 21 contacting the operation fluid are made of a material sensitive to the cavitation emission, i.e., the material which easily emits electrons by the cavitation. Asbestos and fluorine containing synthetic polymers are examples of 35 such material. As mentioned above, the dielectric implant 20 includes at least more than one passage slot 21.

The magnetic body 52 supplies a magnetic field along the channel 51 which is a passage for the operation fluid. 15 Also, the magnetic body 52 has an induction level ranging from one tesla (IT) to two teslas (2T). Particularly, the magnetic body 52 preferably has a rectangular shape having a longer length corresponding to the length of each magnetic body 52 to maximize effects of the magnetic field 20 influencing the flow of the operation fluid. Fig. 5 is a diagram showing a basic concept of the separation unit in accordance with the preferred embodiment of the present invention. As shown, if the magnetic field B is supplied perpendicular to a direction of the flow of 25 the operation fluid including positive and negative ions, the Lorentz force is generated by an interaction between the magnetic field B and the current I due to the flow of the ions. Therefore, positively charged hydrogen ions (H') are separated upward in a perpendicular direction to the 30 ion flow. On the other hand, negatively charged ions (OH-) are separated downward in a perpendicular direction to the ion flow. Each flow of the separated ions goes into two divided separation channels 53.

Especially, the first purification unit 31 receives an 5 operation fluid from an external source through the inlet 41 or from the third discharging pipe 66 of the collection unit 60 shown in Fig. 1 and purifies the operation fluid. The first storage tank 32 stores the purified operation fluid by passing through the first purification unit 31. 10 The second purification unit 33 purifies again the operation fluid temporarily stored in the first storage tank 32. Also, the second storage tank 34 temporarily stores the highly purified operation fluid from the second purification unit 33.
