Technical Field

[0001] The present application relates to the technical field of hydrogen production by electrolysis of water, and in particular to a hydrogen production device, a control method for the hydrogen production device, and related equipment. Background Art

[0002] Hydrogen production by water electrolysis is a process that decomposes water into hydrogen and oxygen through an electrochemical reaction. Common technologies for hydrogen production by water electrolysis include PEM (Proton Exchange Membrane), SOEC (Solid Oxide Electrolysis Cell), AEM (Anion Exchange Membrane), ALK (Alkaline Water Electrolysis), etc.

[0003] Most of the hydrogen production devices in the related technologies adopt a single water electrolysis hydrogen production technology, so there are often certain disadvantages. For example, although the ALK water electrolysis hydrogen production technology is relatively mature and has a long application history, it has the disadvantages of slow dynamic response, not being suitable for rapid start and stop operations, and a relatively narrow operating capacity range. It is sensitive to operating conditions, has a long cold start time, and needs to be preheated to the operating temperature. Although the AEM water electrolysis hydrogen production technology has the advantages of only a short cold start time, fast dynamic response, and the ability to operate at a higher current density, it has the disadvantages of high AEM membrane and catalyst costs.

[0045] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0046] In order to solve the above problems, the present invention provides a hydrogen production device, such as Figure 1As shown, the hydrogen production device 100 mainly includes: a control module 101, an AEM water electrolysis hydrogen production module 102, an ALK water electrolysis hydrogen production module 103, and an electrolyte thermal circulation module 104; wherein the control module 101 is used to obtain the power supply of the external power supply, and coordinately control the AEM water electrolysis hydrogen production module 102 and the ALK water electrolysis hydrogen production module 103 to perform the hydrogen production operation according to the power supply; wherein, when the power supply is lower than the first operating power, the control module 101 is used to generate a first control instruction to control the AEM water electrolysis hydrogen production module 102 to perform the first hydrogen production operation; wherein, the first operating power is determined according to the lower limit of the operating power of the ALK water electrolysis hydrogen production module 103; when the power supply is higher than the first operating power, the control module 101 is used to generate a second control instruction to control the ALK water electrolysis hydrogen production module 103 to perform a second hydrogen production operation, or to generate a third control instruction to control the ALK water electrolysis hydrogen production module 103 and the AEM water electrolysis hydrogen production module 102 to collaboratively perform a third hydrogen production operation; an electrolyte heat circulation module 104 is used to control the AEM electrolyte and the ALK electrolyte to exchange heat during the execution of the hydrogen production operation.

[0047] Based on the above-mentioned hydrogen production device provided by the embodiment of the present invention, when the power supply of the external power supply is low, the power supply at this time is lower than the lower limit of the operating power of the ALK water electrolysis hydrogen production module, the water electrolysis hydrogen production operation can be performed by the AEM water electrolysis hydrogen production module first, which not only broadens the operating capacity range of the hydrogen production device, but also realizes the rapid response rate of the AEM water electrolysis hydrogen production module to quickly respond to hydrogen production, solves the problem of long cold start time of the ALK water electrolysis hydrogen production module, and realizes dynamic high-speed response. At the same time, the heat energy generated during the hydrogen production operation of the AEM water electrolysis hydrogen production module will cause the AEM electrolyte to heat up, and the AEM electrolyte and ALK electrolyte can be controlled by the electrolyte thermal circulation module to exchange heat, so that the temperature of the ALK electrolyte is raised to the hot start temperature range corresponding to the ALK electrolyte, which not only realizes the recovery of heat energy, but also helps to accelerate the cold start process of the ALK water electrolysis hydrogen production module and reduce the energy demand required during its cold start process.

[0048] When the power supply is high, since the ALK electrolyte in the ALK water electrolysis hydrogen production module is preheated in advance, the ALK water electrolysis hydrogen production module can be started to produce hydrogen, or the ALK water electrolysis hydrogen production module can be used to work in conjunction with the AEM water electrolysis hydrogen production module, thereby optimizing energy utilization efficiency under different power input conditions, and also helping to solve the problem of high costs caused by using the AEM water electrolysis hydrogen production module alone. At the same time, the hydrogen production efficiency and effect can be further improved by reasonably allocating the workload of the AEM and ALK water electrolysis hydrogen production modules.

[0049] According to the embodiment of the present invention, the hydrogen production device provided by the embodiment of the present invention avoids the operation of the ALK water electrolysis hydrogen production module at low power, and reduces the frequency of use of the ALK water electrolysis hydrogen production module under inappropriate conditions; and because the heat exchange operation during the hydrogen production operation avoids the temperature of the ALK electrolyte being lower than the hot start temperature, the number of starts and stops of the ALK water electrolysis hydrogen production module is reduced, which helps to extend the service life of the ALK water electrolysis hydrogen production module.

[0050] According to an embodiment of the present invention, when renewable energy (such as wind energy, solar energy, etc.) is used as an external power source, the hydrogen production device provided by the embodiment of the present invention can adapt to the power supply volatility of renewable energy, expand the application scenarios of the hydrogen production device, and improve the utilization rate of green power.

[0051] Through the above-mentioned arrangement, the hydrogen production device provided in the embodiment of the present invention is compatible with the respective advantages of the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module, and compensates for each other's respective disadvantages, thereby achieving high dynamic response and wide range of operation capabilities, while ensuring or even improving the hydrogen production effect and reducing the cost of the hydrogen production device; at the same time, by utilizing thermal energy during the execution of the hydrogen production operation, the energy utilization rate of the hydrogen production process is improved, and the total energy consumption required for the hydrogen production operation is reduced.

[0052] According to a specific implementation of an embodiment of the present invention, a battery energy storage module can also be configured in the above-mentioned hydrogen production device to store excess electricity when the power supply of the external power source exceeds the overall operating power of the ALK water electrolysis hydrogen production module and the AEM water electrolysis hydrogen production module, and release it when the power supply of the external power source is lower, thereby smoothing the power supply fluctuations of the external power source and ensuring the continuity of the hydrogen production operation.

[0053] In some of the embodiments, the hydrogen production device 100 further includes a cooling module, in which a coolant is stored; wherein the cooling module is used to control heat exchange between the coolant and the AEM electrolyte and / or the ALK electrolyte during the hydrogen production operation.

[0054] Stable temperature not only helps to improve the efficiency of hydrogen production, but also prolongs the life of the equipment. Through the heat exchange between the coolant and the electrolyte, the operating temperature of the AEM electrolyte and the ALK electrolyte can be more accurately controlled to ensure that they operate within the optimal hydrogen production temperature range. At the same time, the cooling module provides safety protection for possible overheating of the electrolyte, avoiding equipment damage or reduced hydrogen production effect due to overheating of the electrolyte (exceeding the optimal hydrogen production temperature corresponding to the electrolyte). In addition, combined with the specific workload, the temperature of the electrolyte can be adjusted through the cooling module to adapt to different operating conditions, thereby improving the flexibility and adaptability of the hydrogen production device.

[0055] According to a specific implementation of an embodiment of the present invention, the heat energy recovered through heat exchange between the coolant and the electrolyte in the cooling module can be used for subsequent preheating of the electrolyte or other heat energy utilization processes (such as recovered heat energy for heating, hot water supply or driving other thermal processes), thereby further improving the overall energy utilization rate.

[0056] In some of the embodiments, the AEM water electrolysis hydrogen production module 102 includes a plurality of clusters connected in parallel, and each cluster includes a plurality of AEM stacks connected in series.

[0057] The AEM water electrolysis hydrogen production module of the above structure improves the operating efficiency of the water electrolysis hydrogen production module and further expands the overall operating capacity range of the hydrogen production device. When the power supply is low, the AEM water electrolysis hydrogen production module needs to perform a cold start. The AEM water electrolysis hydrogen production module can be controlled to start a cluster to perform the hydrogen production operation first. After the temperature of the AEM electrolyte rises to the preset temperature, the AEM water electrolysis hydrogen production module is controlled to start cluster by cluster according to the power supply, thereby accelerating the cold start speed of the AEM water electrolysis hydrogen production module and reducing the energy consumption required for the cold start of the AEM water electrolysis hydrogen production module.

[0058] The above-mentioned hydrogen production device provided in the embodiment of the present invention provides a hydrogen production device including a control module, an AEM water electrolysis hydrogen production module, an ALK water electrolysis hydrogen production module, and an electrolyte thermal circulation module; wherein the control module is used to obtain the power supply of an external power supply, and coordinately control the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module to perform a hydrogen production operation according to the power supply; wherein, when the power supply is lower than the first operating power, the control module is used to generate a first control instruction to control the AEM water electrolysis hydrogen production module to perform a first hydrogen production operation; wherein the first operating power is determined according to the lower limit of the operating power of the ALK water electrolysis hydrogen production module; when the power supply is higher than the first operating power, the control module is used to generate a second control instruction to control the ALK water electrolysis hydrogen production module to perform a second hydrogen production operation, or to generate a third control instruction to control the ALK water electrolysis hydrogen production module and the AEM water electrolysis hydrogen production module to collaboratively perform a third hydrogen production operation; the electrolyte thermal circulation module is used to control the AEM electrolyte and the ALK electrolyte to exchange heat during the execution of the hydrogen production operation. The invention overcomes the problems that most of the related technologies adopt a single water electrolysis hydrogen production technology, such as the ALK water electrolysis hydrogen production technology has slow dynamic response, is not suitable for fast start and stop operation, has a relatively narrow operating capacity range, is sensitive to operating conditions, has a long cold start time, and needs to be preheated to the operating temperature; the AEM water electrolysis hydrogen production technology has the problems of high AEM membrane cost and catalyst cost, and realizes the provision of a hydrogen production device with a hybrid water electrolysis hydrogen production module including an AEM water electrolysis hydrogen production module and an ALK water electrolysis hydrogen production module, which is compatible with the advantages of the AEM water electrolysis hydrogen production technology and the ALK water electrolysis hydrogen production technology, and when the operating power is low, the AEM is used to generate hydrogen. The water electrolysis hydrogen production module performs hydrogen production operation to achieve dynamic and rapid response. At the same time, the heat energy of the AEM electrolyte is used to exchange heat with the ALK electrolyte when the AEM water electrolysis module performs hydrogen production operation, so as to realize preheating of the ALK electrolyte, that is, to realize thermal energy management to reduce the energy consumption of hydrogen production, and also to help speed up the cold start process of the ALK water electrolysis hydrogen production module, and reduce the energy demand required in its cold start process, so that both the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module can maintain efficient operation, achieving high dynamic response, wide range of operation capabilities, reducing the cost of hydrogen production equipment and energy consumption loss in the hydrogen production process, and improving the technical effect of hydrogen production efficiency. .

[0059] The embodiment of the present invention also provides a control method for a hydrogen production device, which is applied to a control scenario in which any of the above-mentioned hydrogen production devices performs an operation of electrolyzing water to produce hydrogen. Figure 2 As shown, the control method of the hydrogen production device provided in the embodiment of the present invention mainly includes:

[0060] Step S201, obtain the power supply of the external power supply through the control module, and generate a first control instruction if the power supply is lower than the first operating power, so that the AEM water electrolysis hydrogen production module performs a first hydrogen production operation based on the first control instruction; wherein the first operating power is determined according to the lower limit of the operating power of the ALK water electrolysis hydrogen production module.

[0061] Since the lower operating power limit of the AEM water electrolysis hydrogen production module is lower than the lower operating power limit of the ALK water electrolysis hydrogen production module, and the AEM water electrolysis hydrogen production module has a faster response speed, through the above settings, when the power supply of the external power supply is low, the power supply is lower than the lower operating power limit of the ALK water electrolysis hydrogen production module, the water electrolysis hydrogen production operation can be performed through the AEM water electrolysis hydrogen production module first, which not only broadens the operating capacity range of the hydrogen production device, but also realizes rapid response hydrogen production using the rapid response rate of the AEM water electrolysis hydrogen production module, solves the problem of long cold start time of the ALK water electrolysis hydrogen production module, and realizes dynamic high-speed response. At the same time, it also avoids the ALK water electrolysis hydrogen production module from operating at low power, reducing the frequency of use of the ALK water electrolysis hydrogen production module under inappropriate conditions.

[0062] When the actual operating power is lower than 20% to 30% of the rated operating power of the ALK water electrolysis hydrogen production module, it is difficult for the ALK water electrolysis hydrogen production module to execute the hydrogen production module, or the hydrogen production operation in this case will cause greater damage to the equipment and poor hydrogen production effect; when the actual operating power is higher than 110% to 130% of the rated operating power of the ALK water electrolysis hydrogen production module, it may cause equipment overload, thereby causing damage to the equipment or reducing its service life. The upper and lower operating power limits of the ALK water electrolysis hydrogen production module can be set accordingly. It should be noted that the above values ​​are only examples, and the above values ​​may vary slightly depending on the specific equipment model, manufacturer, etc.

[0063] According to a specific implementation of an embodiment of the present invention, in order to facilitate the distinction between the hydrogen production working ranges of the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module, the embodiment of the present invention provides the concepts of low energy zone and high energy zone. Figure 3As shown, the lower limit of the operating power of the ALK water electrolysis hydrogen production module (that is, the first operating power mentioned above) is used as the upper limit of the low energy zone. When the actual power supply is in the low energy zone, the ALK water electrolysis hydrogen production module is not started to perform the hydrogen production operation, but only the AEM water electrolysis hydrogen production module is started to perform the hydrogen production operation. At the same time, in order to further reduce the impact of low operating power on the ALK water electrolysis hydrogen production module, a 5% margin can be added to the lower limit of the operating power of the ALK water electrolysis hydrogen production module (that is, the first operating power mentioned above). When the actual operating power is higher than the low energy zone, but does not exceed the 5% margin interval, only the AEM water electrolysis hydrogen production module is still used to perform the hydrogen production operation. Furthermore, when the actual operating power is higher than the margin interval, it is divided into a high energy zone. For the high energy zone, when the operating power upper limit of the ALK water electrolysis hydrogen production module is exceeded, the hydrogen production operation of the AEM water electrolysis hydrogen production module must be enabled (at this time, the AEM and ALK water electrolysis hydrogen production modules actually work together to produce hydrogen); if the operating power upper limit is not exceeded, only the ALK water electrolysis hydrogen production module can be used to perform the hydrogen production operation according to actual conditions, or the AEM water electrolysis hydrogen production module and the AEM water electrolysis hydrogen production module can be used to work together to produce hydrogen (at this time, the energy fluctuation of the external power supply is mainly taken into consideration).

[0064] Step S202, during the execution of the first hydrogen production operation, a fourth control instruction is generated by the control module, so that the electrolyte thermal circulation module controls the AEM electrolyte and the ALK electrolyte to exchange heat based on the fourth control instruction, thereby preheating the ALK electrolyte.

[0065] In some of the embodiments, during the execution of the first hydrogen production operation, the electrolyte thermal circulation module controls the AEM electrolyte and the ALK electrolyte to exchange heat based on the fourth control instruction, and the step of preheating the ALK electrolyte also includes: monitoring the second temperature of the ALK electrolyte based on the electrolyte thermal circulation module, and adjusting the heat exchange strategy according to the temperature monitoring result corresponding to the second temperature, so that the second temperature corresponding to the ALK electrolyte is maintained within the ALK hot start temperature range.

[0066] Among them, the ALK hot start temperature range refers to the insulation temperature of the ALK electrolyte when the ALK water electrolysis hydrogen production module can directly achieve hot start. If the second temperature corresponding to the ALK electrolyte is lower than the ALK hot start temperature range, it may be necessary to suspend the operation of the ALK water electrolysis hydrogen production module and preheat the ALK electrolyte before starting the ALK water electrolysis hydrogen production module again. Through the above settings, it is achieved that when the power supply is low, the ALK water electrolysis hydrogen production module can achieve ALK electrolyte preheating and maintain it within the ALK hot start temperature range without a heating device (the ALK water electrolysis hydrogen production module is in a hot start state at this time), thereby improving the dynamic response capability of the ALK water electrolysis hydrogen production module, reducing the number of starts and stops of the ALK water electrolysis hydrogen production module during the hydrogen production process, extending the service life of the ALK water electrolysis hydrogen production module, and at the same time reducing the hydrogen production energy consumption of the ALK water electrolysis hydrogen production module.

[0067] The heat energy generated by the AEM water electrolysis hydrogen production module during the first hydrogen production operation will cause the AEM electrolyte to heat up. Through the above settings, the electrolyte thermal cycle module is used to control the heat exchange between the AEM electrolyte and the ALK electrolyte, so that the temperature of the ALK electrolyte is raised to the hot start temperature range corresponding to the ALK electrolyte, which not only realizes the recovery of heat energy, but also helps to speed up the cold start process of the ALK water electrolysis hydrogen production module and reduce the energy demand required during its cold start process. And because the heat exchange operation during the hydrogen production operation avoids the temperature of the ALK electrolyte being lower than the hot start temperature range, the number of starts and stops of the ALK water electrolysis hydrogen production module is reduced, which helps to extend the service life of the ALK water electrolysis hydrogen production module.

[0068] In some of the embodiments, the method further includes: in response to the power supply of an external power source, controlling the AEM water electrolysis hydrogen production module to perform a first hydrogen production operation through a control module, and during the execution of the first hydrogen production operation, the electrolyte thermal circulation module controls the AEM electrolyte and the ALK electrolyte to exchange heat to achieve preheating of the ALK electrolyte.

[0069] According to an embodiment of the present invention, since the AEM water electrolysis hydrogen production module performs the hydrogen production operation, on the one hand, it can avoid the ALK water electrolysis hydrogen production module from operating at low power, so as to increase the service life of the ALK water electrolysis hydrogen production module; on the other hand, it can also preheat the ALK electrolyte through heat exchange between the AEM electrolyte and the ALK electrolyte, so as to reduce the energy required for heating the ALK electrolyte alone, thereby reducing the cost and energy consumption of the overall hydrogen production operation.

[0070] When the hydrogen production device is started for the first time, it is not necessary to determine the power supply of the external power supply. As long as the power supply of the external power supply is received, the AEM water electrolysis hydrogen production module can be started to perform the hydrogen production operation. After the ALK electrolyte is preheated, it is determined whether the power supply is less than the first operating power; if it is less, the AEM water electrolysis hydrogen production module continues to perform the hydrogen production operation, and the number of clusters started in the AEM water electrolysis hydrogen production module is adjusted according to the actual power supply. If the power supply is greater than the first operating power at this time, and the ALK electrolyte has been preheated at this time, the ALK water electrolysis hydrogen production module can be used to perform the hydrogen production operation, or the ALK water electrolysis hydrogen production module and the AEM water electrolysis hydrogen production module can be used to perform the hydrogen production operation in coordination.

[0071] In some of the embodiments, the AEM water electrolysis hydrogen production module includes a plurality of clusters connected in parallel, each cluster including a plurality of AEM stacks connected in series; the step of controlling the AEM water electrolysis hydrogen production module to perform a first hydrogen production operation through a control module in response to the power supply of an external power supply includes: in response to the power supply of an external power supply, controlling a cluster in the AEM water electrolysis hydrogen production module to start performing a hydrogen production operation, and monitoring a first temperature of the AEM electrolyte; when the first temperature meets the preset hydrogen production temperature of the AEM, controlling the AEM electrolyte to start the hydrogen production operation cluster by cluster according to the operating power corresponding to the external power supply, and controlling the electrolyte thermal circulation module to control the AEM electrolyte to exchange heat with the ALK electrolyte to achieve preheating of the ALK electrolyte.

[0072] Among them, the AEM preset hydrogen production temperature is a temperature pre-set by the user based on different hydrogen production modes, including a first AEM preset hydrogen production temperature preset based on a fast hydrogen production mode and a second AEM preset hydrogen production temperature preset based on an efficient hydrogen production mode.

[0073] The first AEM preset hydrogen production temperature is the rapid hydrogen production temperature corresponding to the AEM water electrolysis hydrogen production module, that is, the hydrogen production capacity of the AEM water electrolysis hydrogen production device has reached the lowest temperature point of the full-flow hydrogen production capacity (generally 20-30°C), and full-flow hydrogen production can be started. Based on the first AEM preset hydrogen production temperature, the AEM water electrolysis hydrogen production module is controlled to start the hydrogen production operation cluster by cluster, which helps to further improve the response efficiency, so it can be called a rapid hydrogen production mode, but at this time the hydrogen production energy consumption is high and the hydrogen production efficiency is low.

[0074] The second AEM preset hydrogen production temperature refers to the temperature when the AEM water electrolysis hydrogen production module reaches the highest hydrogen production efficiency (generally 60-70°C). Based on the first AEM preset hydrogen production temperature, the AEM water electrolysis hydrogen production module is controlled to start the hydrogen production operation cluster by cluster, which helps to improve the hydrogen production efficiency and reduce the energy consumption of hydrogen production.

[0075] Through the above settings, the AEM water electrolysis hydrogen production module adopting the above structure improves the operating efficiency of the water electrolysis hydrogen production module and further expands the overall operating capacity range of the hydrogen production device. When the power supply is low, the AEM water electrolysis hydrogen production module needs to perform a cold start. The AEM water electrolysis hydrogen production module can be controlled to start a cluster to perform the hydrogen production operation first. After the temperature of the AEM electrolyte rises to the AEM preset hydrogen production temperature, the AEM water electrolysis hydrogen production module is controlled to start cluster by cluster according to the power supply, thereby accelerating the cold start speed of the AEM water electrolysis hydrogen production module and reducing the energy consumption required for the cold start of the AEM water electrolysis hydrogen production module.

[0076] According to a specific implementation of the embodiment of the present invention, Figure 4 As shown, when the hydrogen production module is first operated, the AEM water electrolysis hydrogen production module (i.e. Figure 4 The AEM hydrogen production module in the system is cold started. When the AEM water electrolysis hydrogen production module detects the input of electric energy, the first cluster can be started to produce hydrogen. The heat energy generated during the hydrogen production process will heat up the AEM electrolyte. After the AEM electrolyte temperature rises to the preset temperature (which can be set according to actual conditions, it can be set to the AEM hot start temperature range (this setting can further improve the response rate of the hydrogen production module), or it can be set to the AEM optimal hydrogen production temperature (this setting can improve the hydrogen production effect and reduce the total energy consumption of hydrogen production), the hydrogen production operation will be started cluster by cluster according to the actual power supply. Through the above settings, the cold start speed of the AEM water electrolysis hydrogen production module is guaranteed, and the energy consumption required to start the AEM water electrolysis hydrogen production module is reduced.

[0077] Step S203, when the supply power is higher than the first operating power, a second control instruction or a third control instruction is generated by the control module, so that the ALK water electrolysis hydrogen production module performs a second hydrogen production operation based on the second control instruction, or the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module cooperate to perform a third hydrogen production operation based on the third control instruction.

[0078] Through the above settings, when the power supply is high, since the ALK electrolyte in the ALK water electrolysis hydrogen production module has been preheated in advance, the ALK water electrolysis hydrogen production module can be started to perform hydrogen production, or the ALK water electrolysis hydrogen production module can be used to work in conjunction with the AEM water electrolysis hydrogen production module, thereby optimizing energy utilization efficiency under different power input conditions, and also helping to solve the problem of high costs caused by using the AEM water electrolysis hydrogen production module alone. At the same time, the hydrogen production efficiency and effect can be further improved by reasonably allocating the workload of the AEM and ALK water electrolysis hydrogen production modules.

[0079] Among them, the hydrogen production device adopted in the embodiment of the present invention realizes compatibility with the respective strengths of the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module, and compensates for each other's respective shortcomings, thereby achieving high dynamic response and wide range of operation capabilities, while ensuring or even improving the hydrogen production effect and reducing the cost of the hydrogen production device; at the same time, by utilizing thermal energy during the execution of the hydrogen production operation, the energy utilization rate of the hydrogen production process is improved, and the total energy consumption required for the hydrogen production operation is reduced.

[0080] Generally speaking, the optimal hydrogen production temperature range of the AEM water electrolysis hydrogen production module is 60-70°C (AEM materials can show good stability and electrolysis efficiency within this temperature range); under normal circumstances, the AEM water electrolysis hydrogen production module can work normally at lower temperatures, but in order to ensure optimal performance and extend equipment life, it is usually recommended to operate at a certain minimum temperature such as above 20-30°C. This temperature can be recorded as the AEM hot start temperature range corresponding to the AEM electrolyte. When the AEM water electrolysis hydrogen production module is higher than this temperature, it is recorded as a hot start state. The optimal hydrogen production temperature range of the ALK water electrolysis hydrogen production module is 85-95°C (within this temperature range, the electrical conductivity of the ALK electrolyte is relatively high, and the electrolysis efficiency is also relatively high. High temperature helps to reduce the resistance of the electrolyte, thereby improving the current density and energy conversion efficiency); Under normal circumstances, when the temperature of the ALK electrolyte is lower than 40-50°C, it may be necessary to restart and preheat the electrolyte, so 40-50°C can be set as the ALK hot start temperature range corresponding to the ALK electrolyte. At this time, the ALK water electrolysis hydrogen production module is in a hot start state. It should be noted that the specific numerical values ​​corresponding to the above temperatures are only examples and are not intended to be limitations of this application. The above temperature values ​​may vary due to differences in equipment design, equipment type, manufacturer's requirements, and specific types of electrolytes.

[0081] like Figure 5 As shown, the embodiment of the present invention provides a specific example of using the heat energy in the hydrogen production process of the AEM water electrolysis hydrogen production module to preheat the ALK electrolyte, so that the ALK water electrolysis hydrogen production module is switched to a hot start state. When the AEM water electrolysis hydrogen production module is running to produce hydrogen, the ALK electrolyte and the AEM electrolyte are controlled by the electrolyte thermal circulation module to exchange heat (at this time, the heat energy is transferred from the AEM electrolyte to the ALK electrolyte), so that the ALK electrolyte is heated to the ALK hot start temperature range, and the ALK water electrolysis hydrogen production module is in a hot start state. Through the above-mentioned settings, the ALK electrolyte is preheated using the heat energy generated by the AEM water electrolysis hydrogen production module when running to produce hydrogen, thereby accelerating the cold start speed of the ALK water electrolysis hydrogen production module and reducing the energy consumption required for the ALK water electrolysis hydrogen production module to start hydrogen production.

[0082] Step S204, during the execution of the second hydrogen production operation or the third hydrogen production operation, a fifth control instruction is generated by the control module, so that the electrolyte thermal circulation module controls the AEM electrolyte and the ALK electrolyte to perform heat exchange based on the fifth control instruction.

[0083] In some of the embodiments, when the power supply is higher than the first operating power, if the control module generates a second control instruction so that the ALK water electrolysis hydrogen production module performs a second hydrogen production operation based on the second control instruction, the above method also includes: based on the electrolyte thermal circulation module, temperature monitoring is performed on a first temperature corresponding to the AEM electrolyte and a second temperature corresponding to the ALK electrolyte, and the ALK electrolyte and the AEM electrolyte are controlled to exchange heat, so that the first temperature corresponding to the AEM electrolyte is maintained within the AEM hot start temperature range.

[0084] When switching from hydrogen production by only the AEM water electrolysis hydrogen production module to hydrogen production by only the ALK water electrolysis hydrogen production module, taking into account the volatility of the power supply of the external power supply, in order to avoid the need to restart the AEM water electrolysis hydrogen production module to perform hydrogen production operations at any time, the ALK electrolyte and the AEM electrolyte are controlled by the electrolyte thermal circulation hydrogen production module to exchange heat, so as to maintain the temperature of the AEM electrolyte between the hot start temperature and the optimal hydrogen production temperature (the specific value of the temperature maintenance can be determined according to the hydrogen production mode). This can ensure that the AEM water electrolysis hydrogen production module can be hot started at any time, so that the hydrogen production device has the ability to obtain energy and produce hydrogen within the full power range.

[0085] like Figure 6 As shown, the embodiment of the present invention also provides an example of maintaining the temperature of the AEM electrolyte when the ALK water electrolysis hydrogen production module performs the hydrogen production operation. As mentioned above, the ALK electrolyte is preheated in advance so that the ALK water electrolysis hydrogen production module is in a hot start state. When the power supply changes, the control module controls the ALK water electrolysis hydrogen production module to operate hydrogen production, and the ALK electrolyte, AEM electrolyte and coolant are exchanged for heat through the electrolyte heat circulation module and the cooling module, so that the ALK electrolyte and the AEM electrolyte are at the optimal hydrogen production temperature, and the thermal energy is fully utilized, wherein the coolant is to avoid the temperature of the ALK electrolyte and the AEM electrolyte being higher than their respective corresponding optimal hydrogen production temperatures. Through the above-mentioned heat exchange process, the ALK electrolyte is at the optimal hydrogen production temperature, which improves the hydrogen production efficiency of the ALK water electrolysis hydrogen production module; the AEM electrolyte is also maintained at its corresponding optimal hydrogen production temperature, so that the AEM water electrolysis hydrogen production module is maintained in a hot start state corresponding to the optimal hydrogen production temperature, and the hydrogen production process can be cut into at the optimal hydrogen production state at any time.

[0086] In some of the embodiments, when the power supply is higher than the first operating power, if the control module generates a third control instruction so that the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module collaboratively perform a third hydrogen production operation based on the third control instruction, the above method also includes: based on the cooling module, temperature monitoring of a first temperature corresponding to the AEM electrolyte and a second temperature corresponding to the ALK electrolyte is performed, and the coolant is controlled to exchange heat with the ALK electrolyte or the AEM electrolyte respectively, so that the AEM electrolyte and the ALK electrolyte remain within their respective optimal hydrogen production temperature ranges.

[0087] Stable temperature not only helps to improve the efficiency of hydrogen production, but also prolongs the life of the equipment. Through the heat exchange between the coolant and the electrolyte, the operating temperature of the AEM electrolyte and the ALK electrolyte can be more accurately controlled to ensure that they operate within the optimal hydrogen production temperature range. At the same time, the cooling module provides safety protection for possible overheating of the electrolyte, avoiding equipment damage or reduced hydrogen production effect due to overheating of the electrolyte (exceeding the optimal hydrogen production temperature corresponding to the electrolyte). In addition, combined with the specific workload, the temperature of the electrolyte can be adjusted through the cooling module to adapt to different operating conditions, thereby improving the flexibility and adaptability of the hydrogen production device.

[0088] like Figure 7 As shown, in the coordinated hydrogen production process of the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module, the AEM electrolyte, the ALK electrolyte and the coolant are controlled to perform heat exchange, so that the AEM electrolyte and the ALK electrolyte are respectively maintained at their respective optimal hydrogen production temperatures, that is, the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module are maintained at the optimal efficiency point for hydrogen production.

[0089] According to a specific implementation of an embodiment of the present invention, the heat energy recovered through heat exchange between the coolant and the electrolyte in the cooling module can be used for subsequent preheating of the electrolyte or other heat energy utilization processes (such as recovered heat energy for heating, hot water supply or driving other thermal processes), thereby further improving the overall energy utilization rate.

[0090] In some of the embodiments, when the power supply power is higher than the first operating power, the method further includes:

[0091] Based on the control module, the ALK water electrolysis hydrogen production module is controlled to perform hydrogen production operations, so that the ALK water electrolysis hydrogen production module absorbs electric energy from an external power supply to produce hydrogen according to its own electric energy absorption capacity; when the rate of change of the electric energy of the external power supply is greater than the hydrogen production rate of the ALK water electrolysis hydrogen production module, the AEM water electrolysis hydrogen production module is controlled to absorb excess external electric energy to produce hydrogen, so as to ensure the stable operation of the ALK water electrolysis hydrogen production module.

[0092] Through the above settings, the control method of the hydrogen production device provided by the present invention realizes a hydrogen production matching solution for fluctuating energy, realizes the effective and stable absorption and utilization of highly fluctuating external electrical energy, helps to improve the hydrogen production efficiency, ensure the hydrogen production effect, and ensure the stable operation of the ALK water electrolysis hydrogen production module. At the same time, as the ability to absorb dynamic electrical energy increases, it also helps to improve the energy utilization efficiency of the hydrogen production device.

[0093] The control method of the above-mentioned hydrogen production device provided in the embodiment of the present invention adopts the method of obtaining the power supply of the external power supply through the control module. If the power supply power is lower than the first operating power, a first control instruction is generated, so that the AEM water electrolysis hydrogen production module performs the first hydrogen production operation based on the first control instruction; wherein the first operating power is determined according to the lower limit of the operating power of the ALK water electrolysis hydrogen production module; during the execution of the first hydrogen production operation, a fourth control instruction is generated by the control module, so that the electrolyte thermal circulation module controls the AEM electrolyte and the ALK electrolyte to exchange heat based on the fourth control instruction, so as to preheat the ALK electrolyte; when the power supply power is higher than the first operating power, a second control instruction or a third control instruction is generated by the control module. Control instructions are provided to enable the ALK water electrolysis hydrogen production module to perform a second hydrogen production operation based on the second control instructions, or to enable the AEM water electrolysis hydrogen production module and the ALK water electrolysis hydrogen production module to collaboratively perform a third hydrogen production operation based on the third control instructions; during the execution of the second hydrogen production operation or the third hydrogen production operation, a fifth control instruction is generated by the control module to enable the electrolyte thermal circulation module to control the AEM electrolyte and the ALK electrolyte to perform heat exchange based on the fifth control instruction. This technical means achieves the goal of reducing the cost of hydrogen production and improving the efficiency of hydrogen production while meeting the hydrogen production effect of a wide range of operating capabilities and high dynamic response, and also achieves thermal energy management of the hydrogen production process, reduces the energy consumption of hydrogen production, and extends the service life of the ALK water electrolysis hydrogen production module.
