[0002] Global new energy product technologies are divided into three technical routes: pure electric, plug-in hybrid (including series, parallel, and hybrid), and hydrogen fuel cells; but they all have disadvantages such as short driving range, relatively high cost, and high technical difficulty. Since methanol is a relatively safe, economical, large-scale, and conveniently stored and transported fuel, it has been widely recognized and vigorously promoted at home and abroad.

[0003] At present, the technical structures of products using methanol as fuel include: 1. Combining a methanol engine with a generator to generate electricity and charge lithium batteries; or directly using a methanol engine as a driving force. However, methanol engines have problems such as difficulty in cold start, incomplete combustion, low engine power, and corrosion of parts; 2. Using methanol to produce hydrogen, supply hydrogen fuel cells to generate electricity, and then charge lithium batteries. The disadvantage of this structure is that the cost of fuel cells is too high and the purity requirements of hydrogen are also very high.

[0004] By improving the deficiencies of the above technical solutions, the following solution was developed, which combines a methanol reforming hydrogen generator with a hydrogen internal combustion engine and a generator, and generates electricity through regulation by a control system. The advantage of this structural combination is that it can achieve mobile power generation and greatly reduce costs compared to the technical route of fuel cell power generation, especially greatly reducing the difficulty of hydrogen fuel use (storage, transportation, refueling, safety).

A pressure valve 123 is arranged in the methanol reforming hydrogen generator 7; a water squeezing mechanism 4, wherein the water squeezing mechanism 4 is connected to a water distribution pipe 1131, wherein one end of the water distribution pipe 1131 is closed and the other end is open, and a plurality of water outlet holes are evenly arranged on the pipe wall of the water distribution pipe 1131; the water distribution pipe 1131 is laid to the back side of the heat dissipation coil 113, and a blowing part is arranged behind the back side of the heat dissipation coil 113; a filter screen 112, wherein the filter screen 112 is arranged at the air inlet position of the blowing part, and a cleaning mechanism 2 is arranged on the filter screen 112.

[0054] like Fig.10 As shown, in a specific implementation, it also includes a lithium battery assembly 10; the hydrogen internal combustion engine 5 is connected to a generator set 6, and the hydrogen internal combustion engine 5 and the generator set 6 are both connected to the lithium battery assembly 10; the methanol reforming hydrogen generator 7 is connected to a hydrogen compressor 8, and the hydrogen compressor 8 is connected to a hydrogen cylinder 9, and the hydrogen cylinder 9 is connected to the hydrogen internal combustion engine 5.

[0055] The above-mentioned improved structure for using methanol as fuel in hydrogen fuel cells is proposed.

[0056] Specifically, the above structure uses the electricity of the lithium battery assembly 10 and the hydrogen in the hydrogen bottle 9 to start the hydrogen internal combustion engine 5; the hydrogen produced by the methanol reforming hydrogen generator 7 is input into the hydrogen bottle 9 through the hydrogen booster pump; the hydrogen in the hydrogen bottle 9 is supplied to the hydrogen internal combustion engine 5; the hydrogen internal combustion engine 5 drives the generator 110 to generate electricity, which is input into the lithium battery assembly 10.

[0057] The hydrogen from the methanol reforming hydrogen generator 7 is input into the hydrogen cylinder 9 through the pipeline via the hydrogen compressor 8; the hydrogen in the hydrogen cylinder 9 is sprayed into the hydrogen internal combustion engine 5 through the pipeline to burn and do work; the power output end of the hydrogen internal combustion engine 5 is equipped with a generator 110, and the generated current is input into the lithium battery pack through the wires and the control device; the exhaust pipe 3 of the hydrogen internal combustion engine 5 draws out a high-temperature airflow to heat the methanol hydrogen generator.

[0058] The above structure is developed based on the shortcomings of hydrogen fuel cell vehicles currently promoted by the country, such as difficulty in hydrogen storage, transportation and refueling, high cost of fuel cells, and low efficiency of mobile hydrogen production. At present, fuel cell vehicles use 35 MPa or even 70 MPa pressure vessels for hydrogen storage and transportation, which is very expensive, has high requirements for the construction of hydrogen refueling stations, and is very dangerous, and even explosion accidents may occur; in addition, fuel cell technology is difficult, costly, short in service life, and requires the use of 99.99% pure hydrogen. Although hydrogen fuel cell vehicles have a longer driving range than pure electric vehicles, due to the above problems, they are not suitable for large-scale entry into the market.

[0059] The above-developed structure replaces hydrogenation by adding methanol; since methanol is a relatively safe, economical fuel with large reserves and convenient storage and transportation, it can solve the above-mentioned problems.

[0060] Furthermore, the high-temperature airflow discharged from the exhaust pipe 3 of the hydrogen internal combustion engine 5 of the above structure heats the methanol hydrogen generator, thereby realizing the utilization of the heat of the exhaust airflow and avoiding direct discharge and waste.

[0061] In the specific implementation, the optimal temperature for methanol reforming to produce hydrogen is 250-300 degrees, and the optimal pressure is 0.1-0.5Mpa. Based on the above, further improvement is made; the high-temperature gas led out from the exhaust pipe 3 of the hydrogen internal combustion engine 5 is cooled so that the temperature of the gas entering the hydrogen generator is controlled within the range of 250-300 degrees. At the same time, the gas pressure is controlled by the pressure relief valve and maintained at 0.1-0.5Mpa.

[0062] The above-mentioned temperature and pressure control is achieved through the temperature and pressure control mechanism 1.

[0063] Specifically, when the temperature of the exhaust pipe 3 of the hydrogen internal combustion engine 5 reaches a certain temperature of 250 degrees, a hot air flow is drawn out from the exhaust pipe 3 to heat the methanol reforming hydrogen generator 7 .

[0064] Temperature sensors are installed at the inlet and outlet of the exhaust pipe 3 for feedback sensing. The motor 110 and the water pump 104 in the temperature and pressure control mechanism 1 are connected to the control system, and the motor 110 and the water pump 104 are controlled by the feedback sensor signal, such as controlling the speed.

[0065] The gas temperature and pressure in the methanol reforming hydrogen generator 7 are 250-300 degrees and 0.1-0.5 MPa respectively. The temperature and pressure are controlled and adjusted by the temperature and pressure control mechanism 1 to achieve the above temperature and pressure.

[0067] Among them, the water in the water tank 102 is discharged into the water cavity through the connecting pipe 111 to provide cooling for the exhaust pipe 3. The water in the water cavity is sucked by the water pump 104, and the water enters the heat dissipation coil 113 through the pumping pipe 105, the water pump 104, and the return pipe 107.

The external air enters through the air inlet 109, and is filtered by the filter 112 before entering, and then blown onto the heat dissipation coil 113 for blowing and heat dissipation. The heat-dissipated airflow is discharged through the air outlet 108.
