Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a wind-solar integrated hydrogen fuel cell device. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy; its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are respectively supplied to the anode and the cathode. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external electrical load, thereby forming an electrical circuit path to achieve the purpose of powering the electrical load. Due to its advantages of no pollution, no noise, and high efficiency, it has good application prospects. Wind power generation and photovoltaic power generation generate electricity through wind and sunlight respectively, not only having the characteristics of no pollution, etc., but also having the advantage of energy conservation because no fuel is required. In the prior art, due to the conditional limitations of the electrical energy generated by wind power generation and photovoltaic power generation (such as no wind, rainy days, and nights, wind power generation and photovoltaic power generation cannot operate normally), in order to ensure the stable power supply of the electrical load, generally, a storage battery, etc. will be used to store the generated electrical energy, and then when wind power generation or photovoltaic power generation stops generating electricity, the storage battery is controlled by a control circuit to supply power to the electrical load (generally, the direct current output by the storage battery is converted into alternating current by a power inverter to supply power to the electrical load).

[0003] Although, currently, through the method of storing electricity in a storage battery, the electrical energy generated by wind power generation and photovoltaic power generation usually can be stored, but the capacity of the storage battery to store electrical energy is limited. In this way, when the power of wind power generation and photovoltaic generators is relatively large, a large number of storage batteries need to be equipped, which will increase the cost investment. Moreover, after the storage battery has been used for a long time and affected by factors such as its own calendar life, its own power storage capacity will become poor. That is to say, when the subsequent power storage capacity is poor, it cannot ensure the effective and complete storage of the electrical energy output by wind power generation or photovoltaic generators, which will cause waste of electrical energy. Correspondingly, replacing the storage battery that cannot store electricity normally will also bring a large cost investment. Considering the problems that existing hydrogen fuel cells require continuous supply of oxygen and hydrogen and have relatively high power generation costs, it is very necessary to provide a hydrogen fuel cell device based on a hydrogen fuel cell body that can synergistically utilize wind power generation and photovoltaic generator power generation, generate hydrogen and oxygen through a water electrolysis hydrogen production device, and provide a gas source for the hydrogen fuel cell body. Summary of the Utility Model

[0019] Figure 1 , 2As shown in the figure, when the present new type is working, the hydrogen fuel cell body 1 directly converts the chemical energy of the hydrogen input through the hydrogen inlet pipe and the oxygen input through the oxygen inlet pipe into electric energy. The basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are respectively supplied to the anode and the cathode. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through the external electrical load, thereby forming an electrical circuit path to achieve the purpose of supplying power to the electrical load (the above is the existing mature technology, and this application will not elaborate on the working process and principle of the hydrogen fuel cell body nor claim technical protection). Under the action of wind, the DC wind turbine M and under the action of light, the solar panel G1 respectively generate DC power of about 36V and enter the power input ends of the water electrolysis hydrogen production device 2 and the storage battery G2 (the function of the storage battery G2 is to charge part of the power to supply power to the subsequent short message module, gas compressor, air pressure switch, liquid level detection switch, solenoid valve, etc. to ensure the normal operation of the device; it should be noted that the storage battery used in this application has a very small power, only about 3KW. Compared with the energy storage method of the storage battery group used in the existing wind turbine or solar panel, as an auxiliary device, the number of storage batteries is very small, and even the subsequent maintenance and replacement costs are relatively extremely low. Therefore, there is no problem of high cost and ineffective full charge storage caused by the existing wind power generation and photovoltaic power generation relying on the storage battery to store electricity and supply power to the load). When the water electrolysis hydrogen production device 2 is working, after the water in the mixed alkali solution (which increases the conductivity of water and improves the hydrogen and oxygen production efficiency) entering the electrolytic cell 22 of the water electrolysis hydrogen production device 2 is passed through direct current, the water molecules undergo an electrochemical reaction on the two electrodes supporting the water electrolysis hydrogen production device 2 and are decomposed into hydrogen and oxygen (oxygen is output at the upper end of the anode of the electrode, and hydrogen is output at the upper end of the cathode of the electrode. The above is the existing mature technology, and this application will not elaborate on the working process and principle of the water electrolysis hydrogen production device 2 for producing hydrogen nor claim technical protection). Hydrogen and oxygen respectively enter the intake pipes of the two sets of gas compressors MN. In this application, when the water volume in the water tank 21 is relatively large, the float of the liquid level switch T1 floats and its internal contacts will not close, so the short message module A2 will not send out the first short message; when the water volume in the water tank 21 is relatively small (less than one-fifth of the volume), the float of the liquid level switch T1 drops and its internal contacts will close. Then, the negative pole of the DC 12V power supply output by the DC-DC voltage stabilizing module A1 will enter the 3rd pin of the short message module A2, and the short message module A2 will then send out the first short message stored internally. After the staff not on site receive the first short message on their mobile phones, they can go to the site to add water in time. In the present new type, when the water level in the electrolytic cell 22 exceeds half, the float of the liquid level switch T2 floats and its internal contacts will not close, so the solenoid valve DC1 will not be powered on and work, and the water in the water tank will not enter the electrolytic cell; when the water level in the electrolytic cell 22 is less than half, the float of the liquid level switch T2 drops and its internal contacts will close, so the solenoid valve DC1 will be powered on and work and the valve core will open, and the water in the water tank will enter the electrolytic cell; through the above, the water required for the operation of the water electrolysis hydrogen production device 2 can be ensured.

[0020] Figure 1 、 2 As shown, when the water electrolysis hydrogen production device 2 does not electrolyze water due to various reasons, the pressure in its hydrogen exhaust pipe is relatively low, the internal contacts of the air pressure switch S1 are open, and the relay K1 will not be energized and attracted. Then, the two sets of gas compressors MN will not be energized to work; when the water electrolysis hydrogen production device 2 electrolyzes water normally, the pressure in its hydrogen exhaust pipe is relatively high (for example, higher than 0.01 MPa), the internal contacts of the air pressure switch S1 are closed, and the relay K1 will be energized and attracted to control the power input terminal and the normally open contact terminal to close. Then, the two sets of gas compressors MN (working voltage 36V, power 300W) will be energized to work, compress the incoming oxygen and hydrogen respectively, and then output them to the hydrogen storage tank 6 and the oxygen storage tank 7 respectively; through the above, when the water electrolysis hydrogen production device 2 electrolyzes water normally, the present invention can automatically control the two sets of gas compressors MN to compress the hydrogen and oxygen prepared respectively (the hydrogen storage tank 6 and the oxygen storage tank 7 have a large capacity, can effectively store the compressed hydrogen and oxygen, and supply gas to the hydrogen fuel cell body in real time). In the present invention, when the amount of hydrogen or oxygen in the hydrogen tank 4 or the oxygen tank 5 is sufficient, the internal contacts of the air pressure switch S4 or S5 will not close, then the short message module A2 will not send out the second or third short message; when the amount of hydrogen or oxygen in the hydrogen tank 4 or the oxygen tank 5 is small (for example, the pressure is lower than 0.2 MPa), the internal contacts of the air pressure switch S4 or S5 will close. Then, the negative pole of the DC 12V power supply output by the DC-DC voltage stabilizing module A1 will enter the 4th or 5th pin of the short message module A2, and the short message module A2 will then send out the second or third short message stored internally. After the staff not on site receives the second or third short message on their mobile phones, they can go to the site in time to add hydrogen or oxygen to the hydrogen tank 4 or the oxygen tank 5 through the gas filling pipe 10. In the present invention, when the amount of hydrogen or oxygen in the hydrogen storage tank 6 or the oxygen storage tank 7 is sufficient, the internal contacts of the air pressure switch S2 or S3 will not close, then the relay K2 or K3 will not be energized and attracted, and the power supply output by the storage battery G2 will enter the power input terminals of the electromagnetic valves DC2 or DC3 through the control power input terminals and the normally closed contact terminals of the relay K2 or K3 respectively, and the electromagnetic valves DC2 or DC3 are energized and the valve cores are opened, and the hydrogen or oxygen in the hydrogen storage tank 6 or the oxygen storage tank 7 enters the hydrogen inlet pipe and the oxygen inlet pipe of the hydrogen fuel cell body respectively. When the amount of hydrogen or oxygen in the hydrogen storage tank 6 or the oxygen storage tank 7 is insufficient (for example, the pressure is lower than 0.1 MPa), the internal contacts of the air pressure switch S2 or S3 will close. Then, the relay K2 or K3 will be energized and attracted to control the power input terminal and the normally open contact terminal to close. In this way, the power supply output by the storage battery G2 will enter the power input terminals of the electromagnetic valves DC4 or DC5 through the control power input terminals and the normally open contact terminals of the relay K2 or K3 respectively, and the electromagnetic valves DC4 or DC5 are energized and the valve cores are opened, and the hydrogen or oxygen in the hydrogen tank 4 or the oxygen tank 5 enters the hydrogen inlet pipe and the oxygen inlet pipe of the hydrogen fuel cell body respectively.

[0021] Figure 1 、 2 As shown in 2 , through the above, after the new type generates electricity through a wind turbine (outputting 36V) and a photovoltaic generator (outputting 36V), the water electrolysis hydrogen production device (the upper exhaust pipe at the anode of the electrode outputs oxygen, and the upper exhaust pipe at the cathode of the electrode outputs hydrogen) electrolyzes water to generate oxygen and hydrogen, which are respectively compressed and stored in a hydrogen storage tank and an oxygen storage tank. Compared with the existing battery energy storage method, it can achieve a better energy storage effect (the hydrogen storage tank, oxygen storage tank, gas compressor, water electrolysis hydrogen production device, etc. do not have the problems of long service life or the influence of calendar life and the decline of stored electrical energy efficiency in the existing battery energy storage method); when the gas in the hydrogen storage tank and oxygen storage tank decreases to a certain level, it can automatically switch the hydrogen tank and oxygen tank to supply gas to the hydrogen fuel cell body, and when the gas volume in the hydrogen tank and oxygen tank and the liquid volume in the water tank decrease to a certain amount, it can send a text message to prompt the on-site staff to add water or gas, ensuring the stable and reliable operation of the equipment. Figure 2 In Figure 2 , the models of relays K1, K2, and K3 are DC36V; the DC-DC voltage stabilization module A1 is a finished product of a DC36V to DC12V switching power supply module; the pressure switches S2, S3, S4, and S5 are finished products of adjustable normally closed contact type pressure switches (model QPM11-NC); the pressure switch S1 is a finished product of an adjustable normally open contact type pressure switch (model QPM11-ON); the liquid level switches T1 and T2 are finished products of stainless steel float type normally closed contact liquid level switches; the text message module A2 is a text message alarm module of model GSM 800. The finished product of the text message alarm module has two power input terminals, pins 1 and 2, and signal input ports, pins 3 - 8. After a low-level signal is input to each signal input port, the finished product of the text message alarm module will send a text message via the wireless mobile network. There are text messages stored in the text message alarm module. In this embodiment, there are stored text messages of "water shortage", "hydrogen shortage", and "oxygen shortage". After a low-level signal is input to pins 3, 4, and 5 of the signal input port of the text message alarm module, the text message alarm module can send a text message.
