When the proton exchange membrane fuel cell needs hydrogen, the hydrogen collection device can be opened to transport the hydrogen to the proton exchange membrane fuel cell. However, since hydrogen is an active combustion-supporting gas and a strong oxidant, the hydrogen collection device may explode during transportation or storage, which may easily cause safety accidents. Summary of the invention

At the same time, by setting up a catalyst, the oxidation rate of metal aluminum can be reduced, that is, the activation energy of metal aluminum can be reduced, thereby increasing the contact area between metal aluminum and the reaction medium, so as to achieve the technical effect of increasing the production rate of hydrogen, thereby enabling the hydrogen production device to achieve the technical effect of producing hydrogen as soon as it is used.

[0011] In an optional embodiment, the catalyst is a metal; and / or the catalyst is one or more of metal copper, metal magnesium, metal indium, metal mercury, metal gallium and metal tin.

At the same time, the adjustment of the working state of the fourth pipeline can be controlled by the second control unit, so that the opening and closing of the fourth pipeline can be adjusted as needed, thereby achieving the technical effect of improving the convenience of recovery of the replacement medium.

[0032] In an optional embodiment, the hydrogen production unit comprises:

[0033] A detection element is disposed in the second container, and the detection element is communicatively connected with the first control unit and / or the second control unit, and is used to control the working state of the first control unit and / or the second control unit according to the detected content of the hydrogen in the second container.

[0034] Beneficial effect: By setting the detection element, the hydrogen content in the second container can be directly or indirectly detected. When it is detected that the second container is full of hydrogen, the detection element controls the first control unit to open, so that the hydrogen can enter the unit to be used through the second pipeline. When it is detected that there is no hydrogen in the second container, the detection element controls the first control unit to close and the second control unit to open, so that the replacement medium is discharged back to the second container through the fourth pipeline, thereby realizing the recycling of the replacement medium.

[0035] Alternatively, the detection element only controls the working state of the first control unit, or the detection element only controls the working state of the second control unit.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] Combine the following Figure 1 , describing an embodiment of the present invention.

[0052] According to an embodiment of the present invention, on the one hand, a hydrogen production device is provided, comprising:

[0053] The hydrogen production unit 1 is used to connect to the unit to be used 2, and the hydrogen production unit 1 is used to produce hydrogen and directly transport the produced hydrogen to the unit to be used 2;

[0054] The hydrogen production raw materials are provided in the hydrogen production unit 1, and the hydrogen production raw materials include:

[0055] Metal aluminum and reaction medium, the metal aluminum and reaction medium react to produce hydrogen;

[0056] Catalyst, used to reduce the activation energy of metallic aluminum.

[0057] In the hydrogen production device of this embodiment, the hydrogen produced by the hydrogen production unit 1 is directly transported to the unit to be used 2, and there is no need to set up a hydrogen collection device in the related art, which can avoid the explosion of the hydrogen collection device in the related art, thereby achieving the technical effect of improving the safety of the use of the hydrogen production device. At the same time, by setting up a catalyst, the oxidation rate of metal aluminum can be reduced, that is, the activation energy of metal aluminum can be reduced, thereby increasing the contact area between metal aluminum and the reaction medium, so as to achieve the technical effect of increasing the production rate of hydrogen, thereby enabling the hydrogen production device to achieve the technical effect of producing hydrogen as soon as it is used.

[0058] In addition, in this embodiment, the catalyst is a metal to achieve the technical effect of easy catalyst acquisition. Specifically, the catalyst is an alloy of metal magnesium, metal tin, metal mercury and metal copper. This arrangement can improve the effect of reducing the activation energy of metal aluminum, thereby achieving the technical effect of improving hydrogen production efficiency. At the same time, metal copper has a low cost, which can achieve the technical effect of reducing the production cost of the catalyst.

[0059] Specifically, the content of metal aluminum in the alloy is 77.3wt.%, the content of metal magnesium is 8wt.%, the content of metal tin is 6wt.%, the content of metal mercury is 8wt.%, and the content of metal copper is 0.7wt.%. Based on this, the amount of hydrogen produced by the formed alloy at room temperature is 135mL / g. Compared with only using metal aluminum to react with the reaction medium, under the condition of the same amount of hydrogen produced, the amount of the alloy used is less, thereby achieving the technical effect of saving resources.

[0060] Of course, in other embodiments, the types and contents of metal copper, metal magnesium, metal indium, metal mercury, metal gallium and metal tin may be adjusted.

[0061] In other embodiments, the catalyst may be one of metal copper, metal magnesium, metal indium, metal mercury, metal gallium and metal tin, or other forms of alloys.

[0062] In other embodiments, the type of catalyst can be adjusted according to the design of the hydrogen production raw material. For example, the catalyst can be non-metallic, that is, the catalyst that achieves the technical effect of reducing the activation energy of metal aluminum is within the scope of protection of this application.

[0063] Furthermore, in this embodiment, the metal aluminum and the catalyst are made into an alloy, which can increase the contact area between the metal aluminum and the catalyst. When the alloy is consumed, the alloy can be replaced at any time. Of course, in other embodiments, the metal aluminum and the catalyst can also be kept in contact. Compared with other embodiments, this embodiment can improve the simplicity of the contact setting between the metal aluminum and the catalyst, so as to improve the simplicity of reducing the activation energy of the metal aluminum.

[0064] In addition, in this embodiment, the unit 2 to be used is a battery production device, such as a proton exchange membrane fuel cell. In the use scenario at sea, the hydrogen production unit 1 can be directly connected to the battery production device to realize offshore power generation, thereby achieving the technical effect of improving the convenience of offshore electricity use.

[0065] Of course, in other embodiments, the unit 2 to be used may also be other devices requiring hydrogen, all of which are within the protection scope of the present application.

[0066] In addition, in this embodiment, the reaction medium is water, such as seawater, to achieve the utilization of marine resources. Of course, in other embodiments, the reaction medium may also be other forms of water, such as purified water. Compared with other embodiments, this embodiment sets the reaction medium to seawater to reduce the use of fresh water resources, thereby achieving the technical effect of saving energy.

[0067] In other embodiments, depending on the design of the hydrogen production device, metal aluminum, sodium hydroxide and water may be used to react to generate hydrogen. In this embodiment, seawater is directly used as the reaction medium for hydrogen production without sodium hydroxide being involved in the generation of hydrogen, thereby achieving the technical effect of improving the simplicity of hydrogen generation.

[0068] In addition, combined Figure 1 As shown, the hydrogen production unit 1 comprises:

[0069] The first container 101 is used to contain hydrogen production raw materials;

[0070] One end of the first pipe 102 is connected to the first container 101 , and the other end is used to communicate with the unit 2 to be used.

[0071] The first container 101 is provided to hold the hydrogen production raw material, and the first container 101 cooperates with the first pipeline 102 to directly transport the hydrogen to the unit 2 to be used, thereby achieving the technical effect of improving the convenience of holding the hydrogen production raw material and transporting the hydrogen.

[0072] Specifically, combined Figure 1As shown, the first pipeline 102 is arranged above the reaction medium, that is, the first pipeline 102 is connected to the top of the first container 101, so as to avoid the first pipeline 102 being arranged in the reaction medium. The reaction medium can be transported to the unit 2 to be used through the first pipeline 102 and affect the operation of the unit 2 to be used, so as to achieve the technical effect of improving the purity of the hydrogen transported to the unit 2 to be used.

[0073] The first container 101 includes a hinged first body and a first cover. When it is necessary to put in or replace the alloy formed by metal aluminum and the catalyst, the first cover can be opened to replace and adjust the hydrogen production raw material.

[0074] Furthermore, the outer bottom end of the first container 101 is connected with a fifth pipe 1010, which is connected with seawater and is used to transport seawater into the first container 101, and the fifth pipe 1010 is also provided with a fourth control unit, that is, the fourth control unit includes a third switch 1011 and a third flow control element 1012. Specifically, the third flow control element 1012 is a third flow control valve, which can control the flow rate of the reaction medium in the fifth pipe 1010. The third flow control element 1012 is arranged between the third switch 1011 and the first container 101. When the reaction medium needs to be transported to the first container 101, the third switch 1011 and the third flow control element 1012 are opened to drive the seawater into the first container 101 through the fifth pipe 1010. When the required amount of seawater is reached, the third switch 1011 and the third flow control element 1012 are closed.

[0075] Preferably, the first container 101 is filled with reaction medium, which can reduce the air content in the first body, thereby achieving the technical effect of improving the purity of hydrogen entering the first pipeline 102.

[0076] Of course, in other embodiments, the communication position between the first pipe 102 and the first container 101 may be adjusted to ensure that the position where the reaction medium cannot pass through the first pipe 102 is within the protection scope of the present invention.

[0077] In addition, combined Figure 1 As shown, in this embodiment, the hydrogen production unit 1 includes:

[0078] The second container 103 is connected between the first pipe 102 and the unit 2 to be used, the top end of the second container 103 is connected to the other end of the first pipe 102, and the second container 103 is provided with a replacement medium;

[0079] A second pipe 104, one end of which is connected to the top of the second container 103 and is disposed above the replacement medium, and the other end of the second pipe 104 is connected to the unit 2 to be used;

[0080] A third pipe 105, one end of which is disposed at the bottom of the second container 103, and the other end of which is disposed outside the second container 103;

[0081] The first control unit is disposed on the second pipeline 104 , and is used to control the working state of the second pipeline 104 when hydrogen enters the second container 103 and drives the replacement medium to be completely discharged from the second container 103 through the third pipeline 105 .

[0082] During the production of hydrogen, the passage of the second pipe 104 can be closed by the first control unit. When the hydrogen generated in the first container 101 enters the second container 103 through the first pipe 102, the hydrogen can give pressure to the replacement medium in the second container 103, driving the replacement medium to be discharged to the outside of the second container 103 through the third pipe 105. When the replacement medium flows out of the second container 103, it proves that the second container 103 is full of hydrogen, and then the opening of the second pipe 104 is controlled by the first control unit to lead the hydrogen through the second pipe 104 to the unit 2 to be used. The replacement medium can be used as a signal that the second container 103 is full of hydrogen, so as to achieve the technical effect of improving the purity of the hydrogen entering the unit 2 to be used.

[0083] Preferably, the replacement medium fills the second container 103. Based on this, when the replacement medium in the second container 103 flows out of the second container 103 through the third pipe 105, it can be proved that the second container 103 is full of hydrogen, which can achieve the technical effect of improving the purity of the hydrogen in the second container 103, thereby achieving the technical effect of improving the purity of the hydrogen entering the unit 2 to be used.

[0084] Of course, in other embodiments, the communication position between the first pipe 102 and the second container 103, the communication position between the second pipe 104 and the second container 103, and the communication position between the third pipe 105 and the second container 103 can all be adjusted according to actual needs.

[0085] In addition, combined Figure 1 As shown, in this embodiment, the first control unit includes:

[0086] A first switch 106 is provided on the second pipe 104 and is used to open and close the second pipe 104;

[0087] The first flow control element 107 is disposed on the second pipeline 104 and is used to control the flow of hydrogen in the second pipeline 104 .

[0088] Based on this, the first switch 106 can be used to facilitate the opening and closing control of the second pipeline 104, that is, the connection and interruption of the second pipeline 104 can be adjusted. At the same time, by setting the first flow control element 107, the flow rate of hydrogen in the second pipeline 104 can be adjusted, so as to achieve the technical effect of improving the convenience of hydrogen flow rate adjustment as needed. Of course, in other embodiments, according to the design and actual application of the hydrogen production device, only the first switch 106 or only the first flow control element 107 can be set to achieve the control of the working state of the second pipeline 104.

[0089] In addition, combined Figure 1 As shown, in this embodiment, the hydrogen production device includes:

[0090] The collection container 108 is in communication with the other end of the third pipe 105. Based on this, the replacement medium can be collected by the collection container 108 so as to be reused.

[0091] Furthermore, the hydrogen production device also includes:

[0092] A fourth pipe 109, one end of which is in communication with the collection container 108 and the other end of which is in communication with the second container 103, for discharging the replacement medium back to the second container 103 via the fourth pipe 109;

[0093] The second control unit is disposed on the fourth pipeline 109 and is used to control the working state of the fourth pipeline 109 after the hydrogen production is completed.

[0094] The replacement medium in the collection container 108 is transferred to the second container 103 through the fourth pipe 109, so that the replacement medium can be recovered and reused. At the same time, the second control unit can control the adjustment of the working state of the fourth pipe 109, so that the opening and closing of the fourth pipe 109 can be adjusted as needed, thereby achieving the technical effect of improving the convenience of recovery of the replacement medium.

[0095] In this embodiment, one end of the fourth pipe 109 is connected to the outer bottom of the collection container 108, and the other end of the fourth pipe 109 is connected to the top of the second container 103. Based on this, when the hydrogen in the second container 103 is completely transported to the unit 2 to be used, the first control unit can be closed and the second control unit can be opened, so that the replacement medium can flow back to the second container 103 through the fourth pipe 109, so as to achieve the reuse of the replacement medium, thereby achieving the technical effect of saving energy. When the second container 103 is filled with the replacement medium again, the second control unit is closed to complete the recycling of the replacement medium.

[0096] Specifically, the second control unit includes a second switch 1013 and a second flow control element 1014. The second switch 1013 is arranged between the second flow control element 1014 and the collection container 108. The second switch 1013 can be used to control the on-off of the second pipeline 104, and the second flow control element 1014 can be used to control the circulation speed of the replacement medium, so as to adjust the circulation speed of the replacement medium as needed.

[0097] Of course, in other embodiments, the connection positions between the fourth pipe 109 and the collection container 108 and between the fourth pipe 109 and the second container 103 may also be adjusted, as long as the replacement medium in the collection container 108 can be recovered into the second container 103 through the fourth pipe 109.

[0098] In addition, combined Figure 1 As shown, the hydrogen production unit 1 comprises:

[0099] The third control unit 1015 is disposed on the first pipeline 102, and can control the working state of the first pipeline 102 through the third control unit 1015 to realize the on-off of hydrogen entering the second container 103 through the first container 101. That is, when hydrogen needs to enter the second container 103, the third control unit 1015 is turned on to allow hydrogen to enter the second container 103. When hydrogen does not need to enter the second container 103, the third control unit 1015 is turned off.

[0100] Specifically, the third control unit 1015 is a common switch valve. Of course, in other embodiments, depending on the design and actual application of the hydrogen production device, the third control unit 1015 can also be a hydraulic air valve. As a convertible implementation, the third control unit 1015 can also include a switch and a flow control element.

[0101] In addition, in this embodiment, the first switch 106, the second switch 1013 and the third switch 1011 are all ordinary switch valves, the first flow control element 107 is a micro air pump, and the second flow control element 1014 and the third flow control element 1012 are micro flow pumps. Of course, in other embodiments, according to the design and actual application of the hydrogen production device, the first switch 106, the second switch 1013 and the third switch 1011 can also be gas-liquid linkage ball valves, the first flow control element 107 can also be an ordinary air pump, and the second flow control element 1014 and the third flow control element 1012 are ordinary water pumps.

[0102] In this embodiment, the displacement medium is seawater to achieve the utilization of marine resources. Of course, in other embodiments, the displacement medium may also be pure water. Compared with other embodiments, this embodiment sets the displacement medium as seawater to reduce the use of fresh water resources, thereby achieving the technical effect of saving energy.

[0103] In addition, in this embodiment, the hydrogen production device includes:

[0104] The detection element is arranged in the second container 103, and the detection element is communicatively connected with the first control unit and the second control unit, and is used to control the working state of the first control unit and the second control unit according to the detected hydrogen content in the second container 103 and the replacement medium content in the second container 103.

[0105] By providing a detection element, the content of hydrogen in the second container 103 can be detected, and the first control unit and the second control unit can be turned on and off, thereby achieving a technical effect of improving the ease of use of the hydrogen production device.

[0106] Furthermore, in the present embodiment, the hydrogen production device also includes a host computer, which is communicatively connected to the detection element, can read the detection result of the detection element, and control the detection element to detect the content of hydrogen and the content of the replacement medium in the second container 103, and control the working states of the first control unit, the second control unit, the third control unit 1015, the third switch 1011 and the third flow control element 1012 according to the detection results.

[0107] Of course, in other embodiments, a control circuit may be provided in the detection element, which can also achieve the technical effect of communicating with the detection element.

[0108] In addition, in this embodiment, the detection element includes a hydrogen sensor and a liquid sensor. The hydrogen sensor can detect the presence and concentration of hydrogen in the second container 103. The liquid sensor can detect the liquid level of the replacement medium in the second container 103.

[0109] Preferably, the detection element can also be connected to the third control unit 1015 for communication. Based on this, the working process of the hydrogen production device is as follows:

[0110] First, the third switch 1011 and the third flow control element 1012 are turned on, so that the reaction medium can enter the first container 101 through the fifth pipeline 1010, and metal aluminum and a catalyst are placed in the first container 101 to start producing hydrogen. At the same time, the third control unit 1015 is turned on, and the first control unit and the second control unit are turned off, so that hydrogen can enter the second container 103 from the first pipeline 102, and the replacement medium in the second container 103 is squeezed, so that the replacement medium in the second container 103 can be discharged into the collection container 108 through the third pipeline 105;

[0111] Next, when the detection element detects that the replacement medium in the second container 103 is all transported to the collection container 108, and at the same time, when the hydrogen concentration in the second container 103 reaches a certain value, it proves that the second container 103 is full of hydrogen. At this time, the host computer controls the third control unit 1015 to close, and separates the metal aluminum and the reaction medium to stop the generation of hydrogen. At the same time, the host computer controls the first control unit to open, and the second control unit, the third switch 1011 and the third flow control element 1012 are still in the closed state. At this time, the first control unit drives the hydrogen in the second container 103 to enter the unit 2 to be used.

[0112] Finally, when the detection element detects that the hydrogen concentration in the second container 103 is close to zero, it proves that the hydrogen in the second container 103 has been completely transported to the unit 2 to be used, and the upper computer controls the first control unit to turn off and the second control unit to turn on. The third control unit 1015, the third switch 1011 and the third flow control element 1012 are still in the closed state. At this time, the second control unit drives the replacement medium in the collection container 108 to be recovered into the second container 103, preparing for the next hydrogen delivery.

[0113] In other embodiments, the working process of the hydrogen production device may also be: first, the third switch 1011 and the third flow control element 1012 are turned on, so that the reaction medium can enter the first container 101 through the fifth pipeline 1010, and metal aluminum and a catalyst are placed in the first container 101 to start producing hydrogen, and at the same time, the third control unit 1015 is turned on, and the first control unit and the second control unit are turned off, so that hydrogen can enter the second container 103 from the first pipeline 102, and the replacement medium in the second container 103 is squeezed, so that the replacement medium in the second container 103 can be discharged into the collection container 108 through the third pipeline 105;

[0114] Next, when the detection element detects that the replacement medium in the second container 103 is all transported to the collection container 108, and at the same time, when the hydrogen concentration in the second container 103 reaches a certain value, it proves that the second container 103 is full of hydrogen. At this time, the host computer controls the first control unit to open, the third control unit 1015 is still in the open state, and the second control unit, the third switch 1011 and the third flow control element 1012 are still in the closed state. At this time, the first control unit drives the hydrogen in the second container 103 to enter the waiting unit 2, and at the same time, the first container 101 can transport hydrogen to the second container 103;

[0115] Finally, when the unit 2 to be used is about to no longer need hydrogen, and the detection element detects that the amount of hydrogen in the second container 103 can cover the amount of hydrogen required by the unit 2 to be used, the third control unit 1015 is controlled to be closed, and at the same time, the metal aluminum and the reaction medium are separated to stop the generation of hydrogen. When the detection element detects that the concentration of hydrogen in the second container 103 is close to zero, it proves that the hydrogen in the second container 103 has been completely transported to the unit 2 to be used, the detection element controls the first control unit to be closed, the second control unit to be opened, and the third control unit 1015, the third switch 1011 and the third flow control element 1012 are still in the closed state. At this time, the second control unit drives the replacement medium in the collection container 108 to be recovered into the second container 103 to prepare for the next hydrogen delivery.

[0116] Of course, in other embodiments, the detection element is only communicatively connected to the first control unit or the detection element is only communicatively connected to the second control unit.

[0117] In other embodiments, the detection element may only include a hydrogen sensor to achieve the technical effect of detecting the concentration of hydrogen in the second container 103 .

[0119] The above-mentioned hydrogen production device;

[0120] The battery production device, such as a proton exchange membrane fuel cell, is connected to the hydrogen production device to receive hydrogen from the hydrogen production device. Because the battery production system includes the hydrogen production device, it has the same effect as the hydrogen production device, and will not be described in detail here.

[0121] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
