Description

Technical Field

[0001] The present invention relates to the technical field of electric underwater transport tools, and in particular to a ship based on a solid hydrogen pool and a control method thereof. Background Art

[0002] Conventional ships usually use diesel as energy, causing a lot of air pollution. At present, most international trade is completed through ship transportation, and the environmental pollution caused by this cannot be underestimated. In recent years, new energy ships have also been actively developed. Commercial ships that use methanol, LNG, etc. as energy forms also produce carbon emissions. Ships that use pure electricity or battery replacement mode are suitable for small and medium-sized ships. They have limited endurance and high cost of battery replacement infrastructure. They can only be used on fixed routes. At the same time, there are safety hazards such as fire in power batteries.

[0003] Hydrogen energy is a renewable secondary energy source and an important resource for solving the future energy crisis. With the continuous reduction of fossil energy and the continuous increase in pollution, hydrogen energy is known as a good carrier that can replace traditional energy in a clean manner. And because hydrogen energy has no pollution, high environmental friendliness and high energy conversion efficiency in the process of energy conversion, especially in the fields of transportation and power generation and energy storage, it is playing a key social role as a substitute for traditional fossil energy to provide a steady stream of electricity and heat energy for the transportation and thermal power fields. The use of hydrogen energy as an energy source is mainly converted into electricity through fuel cells. It can be used in various fields that require the use of electricity, such as sea, land, air, and space, especially in recent years, the application of hydrogen in the field of ships has been continuously innovated. Hydrogen fuel cells mainly use gaseous or liquid hydrogen to store the fuel required for power. However, under the conditions of very limited aircraft space and aircraft weight, it is impossible to carry more fuel, resulting in limited cruising capabilities of ships and inability to meet long-distance transportation.

[0004] At present, solid-state hydrogen storage can achieve high safety and high hydrogen storage density. However, the existing solid-state hydrogen storage methods cannot meet the needs of ships, especially hydrogen storage materials with high hydrogen storage density. The hydrogen storage density after hydrolysis reaction is much higher than that of existing gaseous, liquid and conventional solid-state hydrogen storage, and the heat generated by hydrolysis is large, resulting in the current hydrogen fuel cell ships using gas hydrogen storage or conventional solid-state hydrogen storage cannot solve the problem of long endurance.

DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0020] The present invention discloses a ship based on a solid hydrogen pool, such as Figure 1 and Figure 2As shown, it includes a hull 1, a paddle module 2 arranged at the rear end of the hull 1, and a fuel cell module 3, a solid hydrogen pool module 4, and an integrated heat dissipation module 5 arranged in the hull 1. The fuel cell module 3 includes a battery stack unit 31 and an air intake and exhaust unit 32. The battery stack unit 31 is connected to the paddle module 2, and the air intake and exhaust unit 32 is connected to the battery stack unit 31, and is used to quantitatively transport air to the battery stack unit 31. The solid hydrogen pool module 4 includes a solid hydrogen storage unit 41, a water injection unit 42, and a hydrogen transmission buffer unit 43. The water injection unit 42 is connected to the solid hydrogen storage unit 41, and is used to introduce seawater and inject it into the solid hydrogen storage unit 41. The hydrogen transmission buffer unit 43 connects the solid hydrogen storage unit 41 and the battery stack unit 31, and is used to buffer the hydrogen release pressure of the solid hydrogen storage unit 41 and transport hydrogen to the battery stack unit 31. The integrated heat dissipation module 5 includes a first heat dissipation unit 51, a second heat dissipation unit 52, and a third heat dissipation unit 53. The first heat dissipation unit 51 includes a first heat exchanger 511 and a first water pump 512. The first heat exchanger 511 is provided with a first medium channel, a second medium channel and a third medium channel. The inlet of the first water pump 512 is connected to seawater, and the medium outlet of the first water pump 512 is connected to the medium inlet of the first medium channel, and the medium outlet of the first medium channel is connected to seawater. The second heat dissipation unit 52 includes a first medium circulation pipeline 521, and the battery stack unit 31 is connected to the second medium channel through the first medium circulation pipeline 521 for heat exchange. The third heat dissipation unit 53 includes a second medium circulation pipeline 531, and the solid hydrogen storage unit 41 is connected to the third medium channel through the second medium circulation pipeline 531 for heat exchange.

[0021] Through the implementation of the above-mentioned ship embodiment, a super solid-state hydrogen pool system is formed by combining the fuel cell module 3 and the solid-state hydrogen pool module 4. The hydrogen produced by hydrolysis in the solid-state hydrogen storage unit 41 is supplied to the battery stack unit 31. The hydrogen delivered by the hydrogen transmission buffer unit 43 and the air provided by the air intake and exhaust unit 32 are electrochemically catalyzed to form an electrochemical reaction inside the battery stack unit 31 to release electrical energy, and converted into energy for driving the paddle module 2. At the same time, by directly extracting seawater as the water source for the hydrolysis hydrogenation reaction of the solid-state hydrogen storage unit 41, it can be used at any time without carrying additional water resources, which greatly reduces the cost. In addition, the setting of the hydrogen transmission buffer unit 43 can have a stable hydrogen storage capacity to ensure that the needs of the fuel cell module 3 can be maintained when no hydrogen release reaction is carried out inside the solid-state hydrogen storage unit 41. On this basis, combined with the integrated heat dissipation module 5, the first heat dissipation unit 51 uses seawater as a heat exchange medium, and directly pumps seawater into the first medium channel of the first heat exchanger 511 through the first water pump 512, and discharges the pumped seawater back to the external seawater from the medium outlet of the first medium channel, thereby forming a seawater medium cycle. Then, the first heat exchanger 511 is used to exchange heat with the heat exchange medium in the first medium circulation pipeline 521 and the second medium circulation pipeline 531, respectively, so that based on the application scenario of the ship, the heat dissipation system of the fuel cell module 3 and the solid-state hydrogen pool module 4 is deeply integrated, and seawater is used for continuous and unified heat exchange, so that the second heat dissipation unit 52 dissipates heat for the battery stack unit 31, and the third heat dissipation unit 53 dissipates heat for the solid-state hydrogen storage unit 41. Among them, the temperature control of the solid-state hydrogen storage unit 41 is relatively wide, and needs to meet the range of 60°C-90°C. The battery stack unit 31 has relatively precise temperature control requirements, and the temperature range under different powers needs to be maintained within the range of 70°C-90°C. That is, by making full use of the existing seawater resources, the thermal management of the entire integrated heat dissipation module 5 can be fully maintained to ensure that the solid-state hydrogen storage unit 41 releases hydrogen stably and continuously, and the battery stack unit 31 supplies power stably and continuously, which can greatly save resources and promote the fuel cell module 3 and the solid-state hydrogen pool module 4 to respond efficiently, so as to improve the continuous endurance of the ship.

[0022] Furthermore, combined with Figure 3 As shown, the second heat dissipation unit 52 also includes a second water pump 522, and a second heat exchanger disposed in the battery stack unit 31. The medium outlet of the second heat exchanger, the second water pump 522, the medium inlet of the second medium channel, the medium outlet of the second medium channel, and the medium inlet of the second heat exchanger are sequentially connected through the first medium circulation pipeline 521. The second heat dissipation unit 52 also includes a first medium compensation tank 523, a first compensation pipeline is connected between the medium outlet of the first medium compensation tank 523 and the medium inlet of the second water pump 522, and a first recovery pipeline is connected between the medium inlet of the first medium compensation tank 523 and the medium outlet of the second medium channel.

[0023] Through the implementation of the above-mentioned ship embodiment, the second water pump 522 is a key component of the second heat dissipation unit 52, which is responsible for extracting the heat exchange medium in the second heat exchanger, and after heat exchange and cooling in the first heat exchanger 511, it enters the second heat exchanger to exchange heat for the heat generated by the electrochemical reaction inside the battery stack unit 31, so as to meet the power supply temperature of the battery stack unit 31 and prevent the battery stack unit 31 from overheating. Among them, by controlling the rotation speed of the second water pump 522, stable control of the exchange heat can be achieved to ensure efficient heat control of the electrochemical reaction process inside the battery stack unit 31. In addition, the second water pump 522 is set so that the heat exchange medium in the first medium circulation pipeline 521 can be replenished in time when it is lacking, and when the battery stack unit 31 is about to shut down, the heat exchange medium in the first medium circulation pipeline 521 is recovered to the first medium compensation tank 523 through the first recovery pipeline to avoid the first medium circulation pipeline 521. Residual medium.

[0024] Preferably, the heat exchange medium is a liquid medium, such as water or other liquid medium.

[0025] Furthermore, the third heat dissipation unit 53 also includes a third water pump 532, a medium filter 533, and a third heat exchanger disposed in the solid hydrogen storage unit 41. The medium outlet of the third heat exchanger, the third water pump 532, the medium inlet of the third medium channel, the medium outlet of the third medium channel, the medium filter 533, and the medium inlet of the third heat exchanger are sequentially connected through the second medium circulation pipeline 531. The third heat dissipation unit 53 also includes a second medium compensation tank 534, a second compensation pipeline is connected between the medium outlet of the second medium compensation tank 534 and the medium inlet of the third water pump 532, and a second recovery pipeline is connected between the medium inlet of the second medium compensation tank 534 and the medium outlet of the third medium channel.

[0026] Through the implementation of the above-mentioned ship embodiment, the third water pump 532 is a key component in the third heat dissipation unit 53, which is responsible for extracting the heat exchange medium in the third heat exchanger, and after heat exchange and cooling in the first heat exchanger 511, the impurities in the cooling medium are filtered out by the medium filter 533. The filtered cooling medium then enters the third heat exchanger to exchange heat with the heat generated by the hydrogen release inside the solid hydrogen storage unit 41, wherein the stable control of the exchange heat can be achieved by controlling the rotation speed of the third water pump 532 to ensure efficient heat control of the hydrogen release process. In addition, the second medium compensation tank 534 is set so that the heat exchange medium in the second medium circulation pipeline 531 is replenished in time when it is lacking, and when the solid hydrogen storage unit 41 is about to shut down, the heat exchange medium in the second medium circulation pipeline 531 is recovered to the second medium compensation tank 534 through the second recovery pipeline to avoid the second medium circulation pipeline 531. Residual medium.

[0027] Furthermore, the ship also includes a low-temperature self-starting module. The low-temperature self-starting module includes a first three-way valve 54, a medium bypass 55 and a fourth heat exchanger 56. The first three-way valve 54 is arranged on a pipeline connecting the medium outlet of the second medium channel and the medium inlet of the second heat exchanger. One end of the medium bypass 55 is connected to the first three-way valve 54, and the other end of the medium bypass 55 is connected to the medium outlet of the third water pump 532. The fourth heat exchanger 56 is arranged on the medium bypass 55, the medium inlet of the fourth heat exchanger 56 is connected to the medium outlet of the third heat exchanger, and the medium outlet of the fourth heat exchanger 56 is connected to the medium inlet of the third medium channel.

[0028] Through the implementation of the above ship embodiment, by using the settings of the first three-way valve 54, the medium bypass 55 and the fourth heat exchanger 56, under winter conditions, the first three-way valve 54 is controlled to conduct the medium bypass 55, so that the heat exchange medium at the outlet of the second heat exchanger circulates along the medium bypass 55. And through the heat exchange connection between the fourth heat exchanger 56 and the third heat exchanger, the high-temperature medium at the outlet of the third heat exchanger is introduced into the fourth heat exchanger 56, and the medium in the medium bypass 55 is preheated at low temperature, so that the preheated medium enters the second heat exchanger, and the interior of the battery stack unit 31 is continuously heated to ensure that the interior of the entire battery stack unit 31 will not freeze at low temperatures, so that the heat of the solid hydrogen storage unit 41 dehydrogenating hydrogen is directly converted to the battery stack unit 31 for reuse at the level of the entire ship, so as to increase the overall energy utilization rate and thereby accelerate the response speed of the ship power system.

[0029] Further, the solid-state hydrogen storage unit 41 includes a reaction pool 411, and a plurality of solid-state hydrogen storage components 412 disposed in the reaction pool 411. The water injection unit 42 includes a water storage tank 421, a fourth water pump 422, and a water sprayer 423, the water storage tank 421, the fourth water pump 422, the water sprayer 423, and the reaction pool 411 are connected in sequence, and a seawater injection pipeline is disposed on the water storage tank 421; The hydrogen transport buffer unit 43 includes a buffer tank 431 and a pressure sensor 432. The buffer tank 431 connects the reaction cell 411 and the battery stack unit 31, a one-way valve 433 is provided at the hydrogen inlet of the buffer tank 431, and a safety valve 434 and a stop valve 435 are provided at the hydrogen outlet of the buffer tank 431 in sequence, and the pressure sensor 432 is provided at the outlet side of the buffer tank 431.

[0030] Through the implementation of the above-mentioned ship embodiment, the reaction pool 411 is a place where the solid hydrogen storage component 412 reacts with the aqueous solution to perform hydrolysis and hydrogenation. The extracted seawater is transported to the water storage tank 421 for storage through the seawater injection pipeline, and the fourth water pump 422 is responsible for pumping water from the water storage tank 421 to the water sprayer 423, and by adjusting the opening of the water sprayer 423, the required reaction water can be sprayed into the reaction pool 411 according to the required amount of water, and sprayed on the solid hydrogen storage component 412 accordingly, so as to control the rate of hydrogen release reaction. The hydrogen released by hydrolysis is collected on the upper side of the reaction pool 411 and enters the buffer tank 431 for buffer storage, so that the hydrogen released by the solid hydrogen storage component 412 is quantitatively stored by the buffer tank 431, and a stable hydrogen storage amount can be formed in the buffer tank 431 to ensure that the application of the battery stack unit 31 can be maintained when no hydrogen release reaction is performed in the reaction pool 411, and the pressure change impact caused by the hydrogen release reaction of the solid hydrogen storage component 412 is weakened. The pressure sensor 432 can be combined to monitor the pressure of the hydrogen supply in real time, and the reaction rate can be adjusted at any time through the adjustment of the one-way valve 433 to ensure that the hydrogen supplied to the battery stack unit 31 is within a relatively stable pressure range, so that the hydrogen release rate and hydrogen release pressure can be dynamically adjusted according to the demand for hydrogen by the battery stack unit 31. In addition, the safety valve 434 sets a certain pressure jump upper limit to protect the entire system device and ensure that the pressure can be released in time under overpressure conditions. The stop valve 435 is used to cut off the entire hydrogen intake route.

[0031] As described above, the solid-state hydrogen storage component 412 is preferably composed of hydrogen-filled high-density hydrogen storage materials. The high-density hydrogen storage materials include metal hydrogen storage materials and non-metal hydrogen storage materials, mainly high-density hydrogen storage materials that can release hydrogen by adding water. For example, metal materials such as magnesium (Mg), calcium (Ca), aluminum (Al), hydrogen storage alloys, inorganic ionic compound hydrogen storage materials, carbonaceous hydrogen storage materials, metal organic skeleton compound hydrogen storage materials, etc. Hydrogen storage alloys include binary systems, ternary systems, and multi-element systems, such as lithium hydride (LiH), sodium hydride (NaH), potassium hydride (KH), magnesium dihydride (MgH2O), etc. )、Calcium dihydride( )、Aluminum hydride( ) etc.; Inorganic ionic compound hydrogen storage materials mainly include coordinated hydrides and amino compounds, such as sodium aluminum tetrahydride ( )、lithium borohydride( ) and ammonia borane are both hydrogen storage materials with relatively high hydrogen storage density. In the solid-state hydrogen pool module, a single or multiple hydrogen storage materials with relatively high hydrogen storage density can be selected. Reversible hydrogen storage is not required, only high hydrogen storage density is required. In addition, the multiple solid-state hydrogen storage components 412 in the reaction pool 411 can improve the hydrogen storage density of the solid-state hydrogen pool module 4, and the aqueous solution formed between two adjacent solid-state hydrogen storage components 412 is sprayed into the gap, which can effectively increase the contact area between the hydrogen storage material and the reaction water, and realize the controllability of the contact area between the solid-state hydrogen storage component 412 and the reaction water, thereby realizing the control of the hydrogen release rate and magnitude, and forming an integrated structure with high energy density for the entire solid-state hydrogen pool module 4. In addition, the structure of the solid-state hydrogen pool module 4 is compact, highly integrated, and can be modularized and matrixed. In order to ensure the versatility of storage and replacement of other fuels, the solid-state hydrogen storage unit 41 can also achieve up and down compatibility under different technical conditions. In particular, the multiple solid-state hydrogen storage components 412 arranged in the reaction pool 411 can be quickly replaced.

[0032] Further, air inlets are respectively provided at the cathode of the battery stack unit 31 and on the air filter 321, and the air intake and exhaust unit 32 includes an air filter 321, an air compressor 322 and an intercooler 323 connected in sequence, and the intercooler 323 is connected to the air inlet of the battery stack unit 31. The intercooler 323 is provided with a medium inlet and a medium outlet, the medium inlet of the intercooler 323 is connected to the medium inlet of the second heat exchanger, and the medium outlet of the intercooler 323 is connected to the medium inlet of the second water pump 522.

[0033] Through the implementation of the above-mentioned ship embodiment, the air filter 321 is the first line of defense of the air intake and exhaust unit 32, which is used to filter out dust, impurities and particles in the air to ensure that the air entering the subsequent components and the battery stack unit 31 remains clean. The air compressor 322 is responsible for compressing the filtered air to a certain pressure to provide compressed air for the subsequent cooling process. The intercooler 323 is used to cool the compressed air and allow the cooled air to enter the battery stack unit 31 through the third three-way valve, so as to improve the efficiency of the air and hydrogen mixing reaction in the battery stack unit 31 by lowering the temperature of the air. In addition, the intercooler 323 is used to exchange heat with the first medium circulation pipeline 521, so that the air intake and exhaust unit 32 and the battery stack unit 31 share a heat exchange system, that is, the heat-absorbing medium in the intercooler 323 after heat exchange with the air is introduced into the first medium circulation pipeline 521 through the second water pump 522, and is cooled by the first heat exchanger 511, and then returns to the intercooler 323 to continue heat exchange. Considering the small amount of available space on the ship, the structure of the entire fuel cell module 3 is compact, highly integrated, and can be modularized and matrixed, ensuring the versatility of storage and replacement of other fuels, and contributing to the simplification of the fuel cell module 3.

[0034] Furthermore, a tail outlet is provided at the cathode of the battery stack unit 31, and the tail outlet of the battery stack unit 31 is connected to the first steam-water separator 33 and the second steam-water separator 34 in sequence, and a tail exhaust throttle valve 35 is provided on the inlet side of the first steam-water separator 33. A second three-way valve 324 is provided on the pipeline connecting the intercooler 323 and the air inlet of the battery stack unit 31, and the second three-way valve 324 is connected to the second steam-water separator 34, for leading compressed air into the second steam-water separator 34.

[0035] Through the implementation of the above-mentioned ship embodiment, the first steam-water separator 33 is used to separate the water vapor discharged from the tail after the electrochemical reaction at the cathode in the battery stack unit 31, and the separated water after the steam-water separation is directly discharged from the hull 1, and the separated gas after the steam-water separation is transported to the second steam-water separator 34 for secondary steam-water separation, so as to fully extract and discharge the water in the steam discharged from the tail after the electrochemical reaction in the battery stack unit 31, so as to prevent the situation of excessive humidity and water accumulation in the fuel cell module 3, thereby improving the response ability and service life of the fuel cell module 3. In addition, since the air at the outlet of the intercooler 323 is compressed air, the compressed air is controlled to be introduced into the second steam-water separator 34 through the second three-way valve 324 to balance the pressure in the second steam-water separator 34 and ensure the stable operation of the entire tail.

[0036] Furthermore, a hydrogen inlet and a product outlet are also provided at the anode of the battery stack unit 31. The fuel cell module 3 also includes an anode reaction circulation unit, which includes an ejector 36 and a third steam-water separator 37. The ejector 36 is connected to the hydrogen inlet of the hydrogen transport buffer unit 43 and the battery stack unit 31, and an ejector inlet is provided on the ejector 36. The inlet of the third steam-water separator 37 is connected to the product outlet of the battery stack unit 31, the separated gas outlet of the third steam-water separator 37 is connected to the ejection inlet of the ejector 36, and the separated liquid outlet of the third steam-water separator 37 is connected to the inlet of the second steam-water separator 34.

[0037] Through the implementation of the above-mentioned ship embodiment, in the hydrogen fuel cell, the anode is where hydrogen enters, where hydrogen is oxidized to generate current. However, while the electrochemical reaction is carried out in the battery stack unit 31, a part of the reaction products will flow out from the anode, mainly including unreacted hydrogen and a small amount of water vapor. Therefore, the third steam-water separator 37 is used to separate the reaction products flowing out of the anode of the battery stack unit 31 from gas and liquid to separate the unreacted hydrogen. And by using the setting of the ejector 36, the hydrogen produced by the solid hydrogen storage unit 41 and flowing at a high speed through the ejector 36 produces a low-pressure area to inhale the hydrogen separated by the third steam-water separator 37 and circulate back to the anode of the battery stack unit 31, thereby optimizing the utilization rate of hydrogen, improving the power supply efficiency and stability of the battery stack unit 31, and reducing the waste of hydrogen. At the same time, the separated water at the outlet of the third steam-water separator 37 is introduced into the second steam-water separator 34 for further steam-water separation, so as to fully extract and discharge the water contained in the fuel cell module 3, thereby improving the response capability and service life of the fuel cell module 3.

[0038] Furthermore, combined with Figure 1 and Figure 4 As shown, the ship also includes a power drive module 6, a power battery module 7 and a whole ship control module 8. The solid hydrogen pool module 4, the power battery module 7 and the integrated heat dissipation module 5 are all located at the bottom of the hull 1 and arranged close to the seawater, and the fuel cell module 3 is arranged close to the deck of the hull 1. The power drive module 6 includes a DC-DC conversion unit 61, a DC-AC conversion unit 62, a drive motor 63 and a gear box 64. The power output end of the battery stack unit 31 is electrically connected to the DC-DC conversion unit 61, and the DC-DC conversion unit 61 and the power battery module 7 are electrically connected to the DC-AC conversion unit 62 respectively, and the DC-AC conversion unit 62 is electrically connected to the drive motor 63, and the output end of the drive motor 63 is connected to the paddle module 2 through the gear box 64. The whole ship control module 8 is respectively connected to the power drive module 6, the power battery module 7, the fuel cell module 3 and the solid hydrogen pool module 4 for closed-loop control of the operation of each module according to the power demand of the ship.

[0039] Through the implementation of the above-mentioned ship embodiment, the solid-state hydrogen pool module 4, the power battery module 7 and the integrated heat dissipation module 5 are all located at the bottom of the hull 1 and arranged close to the seawater, so that the solid-state hydrogen pool module 4 and the integrated heat dissipation module 5 can extract seawater at a close distance to perform corresponding functions, and the flowing seawater can more effectively take away the heat of the solid-state hydrogen pool module 4 and the power battery module 7, so as to improve the heat dissipation efficiency of the integrated heat dissipation module 5. The fuel cell module 3 is arranged close to the deck of the hull 1, which can provide more space for other positions of the ship, and protect the fuel cell module 3 from damage when the ship collides, thereby improving the safety of the ship. The paddle module 2 preferably includes a tail propeller.

[0040] In addition, the power battery module 7 is a pure electric battery. By adding the power battery module 7, the power system of the entire ship adopts a hybrid mode of the fuel cell module 3 and the power battery module 7, which can achieve rapid load changes and meet the needs of high dynamic response to ensure the stability of the ship cruising at sea. And when the ship is ready to start, the power battery module 7 can provide the energy required for the entire super solid hydrogen pool system to start. After the actual fuel cell module 3 is started, the entire super solid hydrogen pool system can achieve self-sufficiency without external energy.

[0041] The power drive module 6 is the main part of the entire ship, responsible for converting electrical energy into mechanical energy, driving the propeller module 2 to operate, and thus driving the ship to cruise at sea. Among them, the DC-DC conversion unit 61 converts DC power of different voltages into the required voltage level, so that the DC power generated by the battery stack unit 31 is converted and adjusted to compatible DC power. The DC-AC conversion unit 62 is responsible for converting DC power into AC power, and is responsible for simultaneously converting the electrical energy of the battery stack unit 31 and the power battery module 7 into AC power for starting the drive motor 63, so as to achieve rapid load change and meet the needs of high dynamic response through the hybrid mode of the fuel cell module 3 and the power battery module 7. The gearbox 64 allows the ratio between the speed output by the drive motor 63 and the speed required by the tail propeller to be adjusted. The drive motor 63 usually runs at a higher speed, while the tail propeller requires a lower speed to effectively propel the hull 1. Therefore, the gearbox 64 is used to increase the output torque of the drive motor 63 by deceleration, so as to efficiently start the tail propeller and overcome the resistance of the water, so as to adapt to different cruising states of the ship, such as: starting, cruising, accelerating or stopping.

[0042] The present invention also discloses a control method for controlling the above-mentioned ship, comprising: In response to the ship being powered on in standby mode, inspect the working status of each unit in the fuel cell module 3, the solid hydrogen pool module 4 and the integrated heat dissipation module 5; In response to the working status of each unit satisfying the preset cruise condition, the fuel cell module 3, the solid hydrogen pool module 4 and the integrated heat dissipation module 5 are controlled to enter the standby state, and the hydrogen pressure state in the hydrogen transport buffer unit 43 is detected; In response to detecting that the hydrogen pressure state in the hydrogen transport buffer unit 43 meets the preset start-up condition, the solid hydrogen pool module 4 and the fuel cell module 3 are started in sequence, and the fuel cell module 3 supplies power to the propeller module 2 until the ship starts cruising; According to the cruising state of the ship, the output power of the fuel cell module 3 is dynamically adjusted, and according to the adjusted hydrogen demand of the fuel cell module 3, the hydrogen release rate, hydrogen release pressure and hydrogen release temperature of the solid hydrogen pool module 4 are dynamically adjusted; In response to the ship entering a shutdown state, the propeller module 2 reverses to make the ship enter a reverse thrust phase, and with the demand for an increase in the output power of the fuel cell module 3, the hydrogen release rate of the solid hydrogen pool module 4 is dynamically adjusted to maintain the hydrogen pressure in the hydrogen transport buffer unit 43; In response to the complete shutdown of the ship, the fuel cell module 3 is controlled to enter a cooling and continuous discharge state in sequence until the fuel cell module 3 is shut down, and then the solid-state hydrogen pool module 4 is controlled to enter a stop hydrogen release state until the solid-state hydrogen pool module 4 is shut down.

[0043] Through the implementation of the above control method embodiment, the ship is powered on and started up in preparation stage: fault detection of each system is performed, and the system can proceed to the start-up preparation stage after detection, and the start-up of the solid-state hydrogen pool module 4 is overall better than the fuel cell module 3, ensuring that the solid-state hydrogen pool module 4 is the hydrogen supply for the fuel cell module 3. Since the system power output is large in the ship startup stage and the hydrogen consumption in a short period of time is large, it is necessary to ensure that the hydrogen pressure in the hydrogen transmission buffer unit 43 is higher than the specified limit before the fuel cell module 3 can be started. Ship power system operation stage: the fuel cell module 3 provides different power outputs according to the different operating states of the ship, uses seawater as the hydrolysis raw material, and controls the hydrogen release rate by controlling the water sprayer 423. In the operation stage, the temperature control accuracy requirements of the hydrogen release reaction in the solid-state hydrogen storage unit 41 are relatively low, and it can usually react normally within 60°C-90°C. The temperature control of the fuel cell module 3 is relatively accurate, and the heat exchange of seawater convection is used in the form of heat exchange, and the heat dissipation of the fuel cell module 3 and the solid-state hydrogen pool module 4 is highly integrated, with the temperature control of the fuel cell module 3 as the main, and the temperature control of the solid-state hydrogen pool module 4 as the auxiliary, for overall thermal management. Ship parking stage: The power system performs reverse thrust, the power demand increases, and the solid hydrogen pool module 4 accelerates hydrogen production to maintain hydrogen pressure according to the increase in hydrogen consumption. Power system shutdown stage: The fuel cell module 3 first enters the shutdown stage, and then shuts down the solid hydrogen pool module 4 to stop hydrogen production.

[0044] The solid-state hydrogen pool-based ship of the present invention has a greatly improved hydrogen storage density of the solid-state hydrogen storage unit 41, which is 3-10 times the fuel storage energy density of various current technical solutions, and can greatly improve the cruising capability of the aircraft. At the same time, when refueling or quickly replacing the fuel, only the solid-state hydrogen storage unit 41 needs to be replaced, which is more convenient to operate. Since hydrogen is stored in solid materials, there is no risk of leakage, combustion and explosion, etc. The single transportable base is large, the manufacturing, transportation and filling links are low-cost, there is no waste in the storage process, and storage in a confined space is allowed. There is no explosion risk during the collision process, which improves intrinsic safety.

[0045] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
