Description of the Invention: [Technical Field] The present invention relates to a battery power supply device, and more particularly to a battery power supply device having a dual hydrogen flow supply. [Prior Art] Water is the most abundant element in nature, and its properties are stable and safe. The hydrogen atoms in its constituent components can form hydrogen as a clean energy source for human use. For decades, the industry has struggled to find an economically safe and effective way to make cheap and easy-to-use hydrogen as an energy source. At present, the technology of hydrogen production by electrolysis is known. Although the technology is feasible, there are still many problems that hinder the popularization of its application, such as the need to consume a large amount of electricity for electrolysis, poor energy conversion efficiency, and the generation of unnecessary waste. Technical obstacles such as pollution, electrode wear or excessive volume of the machine system or inability to supply hydrogen are all. Further, hydrogen may be produced by dissolving a metal in an acid, or by reacting alkali metals or alkali earth metal hydrides, or borohydrides with water. However, such reaction techniques are mostly carried out by mixing a solid metal compound or a boron hydride compound with water. In addition to generating nitrogen, solid product waste and waste liquid remain in the reaction system, and some even adhere to the surface of the unreacted raw material to hinder The reaction continues. In addition, such a reaction rate is fast, the amount of the solid reactant is not easily controlled, and a large amount of heat is often released and the hydrogen generated in the oxygen-containing environment 剧烈V reacts violently to cause an explosion, resulting in safety concerns. Japanese Laid-Open Patent Publication No. Hei 8-115733 proposes a reaction metal body in which a heat-resistant electrode is brought into contact with a reaction metal body of 201225405 formed by an aluminum body or a magnesium body which can be disposed in water and water for electrothermal chemical reaction. The tree heat electrode is energized and discharged in water. The method of generating hydrogen gas by the electrothermal chemical reaction between the metal body and the water is described. Japanese Patent Laid-Open Publication No. mG8755 also proposes a method of decomposing water to generate hydrogen gas by heating water below the hall with a catalytic ship. In addition, the fuel cell can be supplied by water and hydrogen to provide a clean, lightweight, anti-ship speed, safe and stable power supply secret, which can effectively solve the problem of air pollution and greenhouse efficiency. There are many different technology money technologies that can be used for the transfer of batteries. However, fuel cells are demineralized due to sputum mineralization, for example, simple battery tools in start/climb/acceleration, constant speed, downhill Different load demands, such as braking, affect the flow rate of hydrogen, so it is impossible to provide continuous and stable power supply. 1 is a schematic diagram of a conventional fuel cell power supply device 100, including an auxiliary secondary battery 110, a hydrogen generator 丨2〇, a fuel cell 140, a water tank 150, a power distributor 130, and a pump 8 〇, cooling water 611 and fuel The hydrogen 401 required for the battery is converted by the fuel cell 140 into an output DC power 113. When the fuel cell changes due to load, for example, when the fuel cell carrier is in different load demands such as start/climb/acceleration, constant speed, downhill deceleration, braking, etc., the power distributor 130 activates the auxiliary secondary battery 11 〇 output charging/discharging The power 113-2' is output to compensate for the shortage or excess of the output power 113-1 of the hydrogen generated by the argon generator 120.

The main disadvantage of the conventional fuel cell powerless device 100 is that, in addition to the power distributor 130, the fuel cell cannot be recovered from waste heat, so that the overall efficiency is poor. In addition, the conventional fuel cell power supply unit 100 still requires a secondary battery. Therefore, it is still not fully effective to solve the conventional knowledge. 201225405 Secondary battery electric vehicles have limited battery life (two to three years) and are disadvantageous in polluting the environment, charging time is too long, and energy density is low.

Further, in the following detailed description of the invention, numerous specific details are set forth However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these specific details. The technical method of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments to make the features and advantages of the present invention more obvious. FIG. 2 is a diagram showing a fuel cell power supply device with dual hydrogen flow supply according to an embodiment of the present invention. 200 schematic. As shown in FIG. 2, the fuel cell power supply device 200 includes a hydrogen gas buffer 10, a reactor 20, a flow controller (mass f|〇w controller, MFC) 30, and a fuel cell (full cell). 4, a sink tank 50, a heat exchanger 60, a hydrogen gas/water separator 70, and pumps 80 and 90. Water m from the water tank 5 and chemical hydrogenation 201225405 1110 are included in the reactor 20. The pump 90 drives the heat exchanger of the heat exchanger 60 to output hot water 602 to provide a heat source for the reaction n 2G to react the reaction || 2G(tetra) chemical nitride mo with the water ini. In one embodiment, the chemical vapor comprises magnesium or magnesium hydride. In one embodiment, water 1111 is reacted with a chemical hydride, including magnesium or hydrogenated money, at room temperature. In one embodiment, to increase the reaction rate of the chemical hydride 1110, the waste heat of the fuel cell 4 recovered by the heat exchanger 60 (not shown) may output the hot water 602 to the heat exchanger to increase the reaction temperature of the reactor 20. To 4〇~6〇. c. φ water 1111 and magnesium or magnesium hydride 1110 generate hydrogen gas by reaction, and hydrogen gas is generated simultaneously with the generation of hydrogen gas. In order to distinguish between hydrogen and water vapor in the gas taken out from the reactor 20, the reactor 2 flows and flows.

The hydrogen reservoir ίο has a metal hydride alloy 1112 that provides or absorbs hydrogen. The metal hydride alloy 1112 is an alloy crystal in which about one metal atom is bonded to about 2, #3 or even more hydrogen atoms, but the crystal structure of the metal hydride alloy 1112 is maintained. Once the conditions change, such as a slight heat, the hydrogen atoms will escape from the crystal voids and be released as argon, while the crystals of the metal hydride alloy 1112 will return to their original state. Therefore, the hydrogen storage process of the metal hydride alloy 1112 is reversible, and it is called "reversible hydrogen storage". The metal hydride alloy 1112 has a large hydrogen storage amount and can be used repeatedly. It can be used as a metal argon alloy lm material. The following conditions must be met. ^The hydrogen storage capacity should be large first. Second, hydrogen absorption and hydrogen release are easy. As long as it is heated slightly, hydrogen can be released and the speed is fast. Third, the service life Long and cheap.

The first series is magnesium-based hydrogen storage alloys, such as magnesium hydride, town-recorded alloys, and the second series is rare earth-based hydrogen storage alloys, such as steel-recorded alloys, mixed rare earth nickels, alloys, mixed rare earth nickels and aluminums. Alloys, etc., the third series is titanium hydrogen storage alloys, such as titanium hydride, titanium-manganese alloys; the fourth series is lanthanide hydrogen storage alloys such as lanthanide hydrogen storage alloys for nickel-hydrogen battery anode materials . In one embodiment, the metal hydride includes, but is not limited to, lithium hydride (LiH), copper hydride (CuH2), magnesium hydride (MgH2), magnesium-nickel hydride (MgNiH4), titanium hydride (TiH2), titanium, iron. Hydrogen alloy (TiFeH1 5), titanium-cobalt hydrogen alloy (TiCoH1.5) 'Titanium-manganese hydrogen alloy (TiMnl.5H2.14), titanium-chromium hydrogen alloy (Τι02Η2.6) or bismuth-nickel hydrogen alloy (LaNi5H6) . The pump 90 also drives the heat exchanger to output hot water 6 〇 2 to provide a heat source to the hydrogen reservoir 1 〇 to react the metal hydride 1112 in the reactor 20. The cooling water 403 required for the beta fuel cell is supplied by the heat exchanger output cold water 〇1. The heat exchanger outputs cold water 601 while taking away the waste heat (not shown) discharged from the fuel cell 4〇. The hydrogen buffer 10 and the hydrogen produced by the reactor 20 are sent to the flow controller 3 through the hydrogen water separator 70 to provide the required field for the fuel cell. The fuel cell output water 402 discharged from the fuel cell* is recovered to the water tank 50 for reuse. In theory, the water tank does not need water. . However, a supplemental water 1M can be used to provide the water tank 50. When the fuel cell power supply device 200 is started, the flow controller 7 can control the hydrogen required for the fuel cell and the hydrogen gas 4Gi and the heat exchanger output required by the hydrogen buffer to carry the fuel cell, and the heat is transferred to the U3G. The waste heat (not shown) discharged from the field of the fuel cell 4 taken out of the cold ice passes through the heat exchanger 201225405 60 to provide the heat exchanger output hot water 602 and to the hydrogen buffer 10 and the reactor 20 via the pump 90. . The hydrogen buffer 10 and the reactor 20 receive the heat energy of the heat exchanger wheel hot water 602 to generate more hydrogen to the fuel cell 40 until the flow controller output hydrogen 301 differs from the hydrogen set point 115 在一 by a predetermined value. Within the scope. Therefore, the waste heat generated by the fuel cell 40 (not shown) can be recovered via the heat exchanger 60 to produce the hydrogen gas 401 required for the fuel cell, thereby making the overall fuel cell power supply apparatus considerably more efficient. When the fuel cell changes due to load, for example, when the fuel cell carrier is in different load demands such as start/climb/acceleration, constant speed, downhill deceleration, braking, etc., if the hydrogen generated by the reactor 20 is insufficient, the flow controller 7 The hydrogen gas generated by the hydrogen buffer 10 can be controlled to directly supply hydrogen to the fuel cell 40 via the hydrogen water separator 70. On the other hand, if the reactor 20 generates too much hydrogen, the flow controller 70 can control the reactor 20 so that the excess nitrogen generated can be directly sent to the hydrogen buffer 1 through the hydrogen water separator 70, thereby further excessive Hydrogen is stored. In this way, in addition to the conventional power distributor of the fuel cell power supply device, the continuity of the hydrogen gas required for fuel power can be greatly improved, so that the fuel cell 40 can generate stable output DC power 1130. In order to greatly improve the power quality of the overall fuel cell power supply. 3 is a schematic diagram of a fuel cell powered electric vehicle 300 with dual hydrogen flow supply in accordance with an embodiment of the present invention.
