Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a storage device for preparing fuel cells. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen passes through the catalyst at the anode, it generates hydrogen ions and electrons. The hydrogen ions that have lost electrons pass through the diaphragm and finally reach the cathode, where they are recombined with the oxygen and electrons at the cathode to form water. In this electrochemical reaction process, only water and heat are generated, which is pollution-free to the environment, and the operation is quiet and noise-free.

[0003] Hydrogen fuel cells are characterized by high efficiency, and their power generation efficiency can reach more than 50%. They directly convert chemical energy into electrical energy without the need for intermediate conversion of thermal energy and mechanical energy. In addition, the electrodes of hydrogen fuel cells are made of special porous materials, which provide a large contact surface for gas and electrolyte and catalyze the chemical reaction of the battery. Fuel cells are a device that uses chemical reactions to generate electrical energy, and its core component is the membrane electrode. The membrane electrode is one of the most important components of a fuel cell. It not only determines the performance of the fuel cell, but also directly affects the life and stability of the fuel cell.

[0004] The membrane electrode is composed of anode and cathode coatings and a proton exchange membrane. The substrate with the cathode coating (also known as the cathode catalyst layer) or the anode coating layer (also known as the anode catalyst layer) is usually stored in the form of a roll. The cathode coating is compounded on one side of the proton exchange membrane, the anode coating is compounded on the other side of the proton exchange membrane, and the substrate is separated, so that the proton exchange membrane has a cathode catalyst layer on one side and an anode catalyst layer on the other side.

[0005] Because cathode coatings and anode coatings are expensive and sensitive to environmental temperature, humidity and impurity content, if randomly stacked and stored, they are prone to loss, bumping, contamination and other problems, which will affect production progress and extend production time. It will also increase product quality risks and cause unnecessary cost waste. However, the storage structure for storing fuel cell preparation materials such as cathode coatings and anode coatings in the prior art is simple. The fuel cell preparation materials are only stored in a storage box, which cannot provide an environment suitable for the storage of fuel cell preparation materials, thereby affecting the performance of the fuel cell preparation materials.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] This embodiment relates to a storage device for preparing fuel cells, comprising a cabinet 1 having a storage cavity, and a plurality of storage boxes 4 slidably arranged in the storage cavity. Each storage box 4 has a storage cavity 100 with an open top, a support portion for supporting fuel cell preparation materials is arranged in the storage cavity 100, and the storage box 4 can slide relative to the cabinet 1 and extend from the cabinet or retract into the storage cavity. The cabinet 1 is provided with an adjustment portion, which is used to adjust the temperature and / or humidity in the storage cavity.

[0031] The storage device for preparing fuel cells described in this embodiment is advantageous for the separate storage and transportation of fuel cell preparation materials by providing a plurality of storage boxes 4, and is advantageous for avoiding the technical problem of low production efficiency caused by mixing different fuel cell preparation materials (e.g., coiled materials for preparing membrane electrode) in the prior art. A support portion is provided in the storage cavity 100 of the storage box 4 to support the fuel cell preparation materials, which is advantageous for improving the convenience of placing the fuel cell preparation materials, and by sliding the storage box 4 relative to the cabinet 1, the storage box 4 can be extended from the cabinet 1 or retracted into the accommodating cavity, thereby facilitating the taking and placing of the fuel cell preparation materials. Furthermore, by providing a regulating portion on the cabinet 1 to regulate the temperature and / or humidity of the accommodating cavity, it is advantageous for ensuring the performance of the fuel cell preparation materials.

[0032] Based on the above overall introduction, an exemplary structure of the storage device for preparing a fuel cell in this embodiment is as follows: Figures 1 to 3 As shown in the figure, the storage boxes 4 are arranged in multiple rows in parallel along the left-right direction of the cabinet 1, and the multiple storage boxes 4 in each row are arranged at intervals up and down. This is conducive to increasing the number of storage boxes 4, so that the storage device for fuel cell preparation can store more fuel cell preparation materials.

[0033] The fuel cell preparation material in this embodiment can be, for example, a coil for preparing a membrane electrode. The coil is wound on a reel, and one surface of the coil is provided with an anode catalyst layer or a cathode catalyst layer. The anode catalyst layer on the coil is arranged on one side of the proton exchange membrane, and the cathode catalyst layer on the coil is arranged on the other side of the proton exchange membrane, thereby facilitating the preparation of the membrane electrode.

[0034] As a preferred embodiment, the cabinet 1 in this embodiment includes a cabinet 1 body having a accommodating cavity, and a frame arranged in the cabinet 1 body, and the frame divides the accommodating cavity into a plurality of mutually connected placement spaces. The plurality of placement spaces correspond one to one with the plurality of storage boxes 4, and each storage box 4 is slidably arranged in the corresponding placement space. The setting of the frame here is conducive to the installation of a plurality of storage boxes 4, and one side of the cabinet 1 body is open. The cabinet body serves as an installation carrier of the frame, and can protect the fuel cell preparation materials, that is, the coils, stored in each storage box 4. In specific implementation, the frame can adopt the storage rack in the prior art, and can meet the installation requirements of the storage box 4.

[0035] The structure of the storage box 4 is as follows: Figure 3 As shown in , it is in the shape of a rectangular parallelepiped, so as to facilitate the placement of fuel cell preparation materials such as coils. Of course, the shape and specifications of the storage box 4 can also be adjusted according to the specifications of the coils. In order to improve the stability of the storage box 4 during sliding, guide structures are provided between the bottom of both sides of the storage box 4 and the bottom of the corresponding placement space.

[0036] In specific implementation, the guide structure can be a slide rail arranged between the storage box 4 and the frame. The slide rail here can refer to the slide rail structure arranged between the drawer and the cabinet 1 in the prior art. It can not only guide the storage box 4 to slide in or out of the corresponding placement space, but also limit the displacement of the storage box 4 in the retracted state toward the inside of the placement space, and the continued displacement of the storage box 4 in the extended state toward the outside of the placement space, thereby helping to improve the use stability of the storage box 4 in the extended state and the retracted state.

[0037] As a preferred embodiment, the support portion includes at least two vertical rods 801 arranged on the bottom wall of the storage cavity 100, and a support rod 8 arranged on the top of each vertical rod 801, and the support rod 8 is arc-shaped and used to support the fuel cell preparation material. Figure 3 As shown in the figure, there are two support rods 8 spaced apart along the length direction of the storage cavity 100. Here, by arranging the support rods 8 at the top of the vertical rods 801, the distance between the support rods 8 and the bottom surface of the storage cavity 100 can be increased. When the reel with the coiled material is placed on the two support rods 8, the outer peripheral wall of the coiled material can be spaced apart from the bottom surface of the storage cavity 100, so as to prevent the coiled material from being scratched against the bottom wall of the storage cavity 100 and damaging the coiled material.

[0038] In addition, the arc-shaped support rod 8 can be beneficial to improve the support effect of the reel, and the support rod 8 has a simple structure and is easy to arrange and implement. Of course, the support rod 8 can also be in other geometric shapes besides the arc shape, as long as the support requirements for the reel are met.

[0039] Furthermore, the storage device in the present embodiment also includes a buffer portion, which is arranged on the side wall of the support rod 8 and / or the storage chamber 100, and can abut against the fuel cell preparation material. For example, the buffer portion includes a first buffer pad arranged on the support rod 8, and the first buffer pad is used to abut against the reel. The provision of the first buffer pad here is conducive to increasing the friction between the reel and the support rod 8, thereby preventing the reel from falling on the support rod 8 due to shaking. At the same time, the first buffer pad can also buffer the vibration transmitted from the support rod 8, thereby improving the placement stability and safety of the reel on the support rod 8. In specific implementation, the first buffer pad can be made of foam or rubber, which is wrapped outside the support rod 8, and has the advantages of easy layout and implementation, as well as good buffering effect.

[0040] During specific implementation, the spacing between the two support rods 8 is preferably greater than 20cm, for example, the spacing between the two support rods 8 can be 21cm, 25cm, 30mm or 35mm, etc., and the spacing between the two support rods 8 here should be adapted to the length of the fuel cell preparation material, so as to improve the supporting effect of the fuel cell preparation material. Preferably, the load-bearing capacity of each support rod 8 is greater than 100Kg to improve the supporting stability of the fuel cell preparation material. In addition, the angle corresponding to the arc-shaped support rod 8 is preferably greater than 120°, for example, the angle of the support rod 8 can be 125°, 130° or 135°, etc. The support rod 8 in this embodiment is preferably made of stainless steel to have higher strength and supporting effect.

[0041] It should be noted that, in this embodiment, the number of support rods 8 is Figure 3 In addition to the two shown in the figure, additional ones can be adaptively added according to the use requirements. In addition to supporting the two ends of the fuel cell preparation material, the support rod 8 can also be made into other positions of the fuel cell preparation material, as long as the support use requirements are met.

[0042] In this embodiment, the buffer portion further includes a shock absorbing pad 9 disposed on the side wall of the storage cavity 100. The provision of the shock absorbing pad 9 can help prevent the outer peripheral wall of the coil from directly contacting the side wall of the storage cavity 100 under extreme conditions, thereby protecting the coil. Figure 3As shown in , the shock absorbing pad 9 is preferably arranged on the side walls of the storage cavity 100 on both sides in the width direction, so that the shock absorbing pad 9 is located on the left and right sides of the support rod 8 to prevent the coil from being damaged by directly hitting the inner wall of the storage cavity 100 when moving to the left and right sides. In specific implementation, the shock absorbing pad 9 can be made of foam or rubber, and the rubber can be polyurethane or shock-absorbing rubber.

[0043] As a preferred embodiment, the storage box 4 in this embodiment is provided with a placement portion 5, a locking portion 7 and a handle 6, wherein the placement portion 5 is used to place a card identifying the stored information, and the locking portion 7 is used to lock the storage box 4 in the retracted state. Figure 1 and Figure 2 As shown in FIG. 1 , the placement portion 5, the locking portion 7 and the handle 6 are all arranged at one end of the storage box 4 facing the outside of the cabinet 1. Figure 1 Only the arrangement of the placement portion 5, the locking portion 7 and the handle 6 on one storage box 4 is illustrated. Of course, the placement portion 5, the locking portion 7 and the handle 6 can also be provided on all storage boxes 4 at the same time to achieve better use effect.

[0044] Among them, the placement part 5 includes a placement slot provided on the end face of the storage box 4 and having a take-in and put-out port. A card marked with the stored information is inserted into the placement slot through the take-in and put-out port. In order to facilitate the formation of the above-mentioned placement slot and to facilitate viewing of the information on the card, a transparent film body is provided on the end face of the storage box 4, and a part of the edge of the film body is bonded to the storage box 4, thereby defining a placement slot between the film body and the end face of the storage box 4. Of course, during specific implementation, the orientation of the take-in and put-out port on the placement slot and the specifications of the placement slot can be adaptively adjusted according to the use requirements. The stored information includes but is not limited to the specifications and models of the coiled materials.

[0045] The locking portion 7 in this embodiment can adopt a mechanical lock or electronic lock in the prior art, which is arranged on the storage box 4, and can lock the storage box 4 in a retracted state on the cabinet 1, and the storage box 4 can be slid only after unlocking the mechanical lock or electronic lock, thereby helping to improve the storage security of fuel cell preparation materials and prevent economic losses caused by the theft of fuel cell preparation materials.

[0046] The handle 6 in this embodiment is in a "U" shape, and its two ends are connected to the end faces of the storage box 4 respectively, so that a space for the hand to pass through is defined between the handle 6 and the storage box 4. The structure of the handle 6 here is simple, easy to process and shape, and has a good use effect. It is understandable that the handle 6 in this embodiment can be in addition to the "U" shape, and can also be in other geometric shapes that are easy to hold, or directly recessed inward on the end face of the storage box 4 to form the structure of the handle 6. It is understandable that in this embodiment, at least one of the placement portion 5, the locking portion 7 and the handle 6 can also be provided, which is also conducive to improving the use effect of the storage box 4.

[0047] As a preferred embodiment, the adjustment unit includes a cooling module and / or a heating module that can adjust the temperature in the accommodating chamber. That is to say, the adjustment unit may only include a cooling module, in which case the adjustment unit can only lower the temperature in the accommodating chamber. Alternatively, the adjustment unit only includes a heating module, in which case the adjustment unit can only increase the temperature in the accommodating chamber. Alternatively, the adjustment unit includes a cooling module and a heating module, in which case the adjustment unit can not only lower the temperature in the accommodating chamber, but also increase the temperature in the accommodating chamber. In specific implementation, the cooling module and the heating module can be selectively arranged according to usage requirements.

[0048] The cooling module and the heating module in this embodiment can both be products in the prior art. For example, the cooling module can be a refrigerator in the prior art, and the heating module can be a heater in the prior art. The working principles of the refrigerator and the heater are roughly the same as the principles of cooling and heating of air conditioners in the prior art.

[0049] For example, a refrigerator can be composed of a refrigeration compressor, a condenser, an evaporator, an electromagnetic reversing valve, a filter and a refrigerant to form a sealed refrigeration cycle. The refrigerator can also include an air duct system, which can be composed of centrifugal fans, axial flow fans and other equipment. The working principle of the refrigerator is: the low-pressure vapor of the refrigerant is sucked in by the compressor and compressed into high-pressure vapor and then discharged to the condenser. At the same time, the outdoor air sucked in by the axial flow fan flows through the condenser, taking away the heat released by the refrigerant, and condensing the high-pressure refrigerant vapor into high-pressure liquid.

[0050] The high-pressure liquid is sprayed into the evaporator after passing through the filter and the throttling mechanism, and evaporates at a corresponding low pressure, absorbing the surrounding heat. At the same time, the cross-flow fan allows air to continuously enter the fins of the evaporator for heat exchange, and sends the air that becomes cold after releasing heat into the accommodation chamber. In this way, the air in the accommodation chamber continuously circulates to achieve the purpose of lowering the temperature in the accommodation chamber. The heater includes an electric heater and an air duct system. When the fan in the air duct system blows through the heater, the temperature of the air flow can be increased, which is conducive to increasing the temperature in the accommodation chamber.

[0051] In specific implementation, the heating module and the cooling module can be arranged on any side wall of the cabinet 1, for example, on the bottom side wall or the back side wall of the cabinet 1, as long as the layout requirements are met. In order to improve the efficiency of the adjustment part in adjusting the temperature in the accommodating cavity, an air intake pipe is provided on the left side of the cabinet 1, and the air intake pipe includes a main pipe 12 and three branch pipes 11 connected to the main pipe 12 and arranged in parallel. The air intake end of the main pipe 12 is connected to the air outlet of the accommodating cavity, and the outlet ends of the three branch pipes 11 are respectively connected to the top, middle and bottom of the cabinet 1.

[0052] An air outlet pipe communicating with the outside is provided at the bottom of the right side of the cabinet 1, and the air flow in the accommodating cavity is discharged to the outside of the cabinet 1 through the air outlet pipe. It can be understood that in specific implementation, the arrangement of the air inlet pipe and the air outlet pipe can be adjusted according to the use requirements.

[0053] As a preferred embodiment, multiple temperature sensors arranged at intervals are also set in the storage cavity to detect the temperature in the storage cavity and serve as a basis for the adjustment unit to adjust the use status of the cooling module and the heating module. For example, when the temperature detected by the temperature sensor is lower than the target temperature threshold, the heating module needs to be turned on to perform the heating mode, and hot air is introduced into the storage cavity through the air inlet pipe. The airflow passes through the gap between the frame and the storage box 4, and then flows into each storage cavity 100, and the temperature in the storage cavity is increased to within the target threshold range.

[0054] When the temperature detected by the temperature sensor is higher than the target temperature threshold, the refrigeration module in the adjustment unit needs to turn on the refrigeration mode and introduce cold air into the storage cavity through the air inlet pipe. The airflow passes through the gap between the frame and the storage box 4, and then flows into each storage cavity 100, and reduces the temperature in the storage cavity to within the target threshold range.

[0055] In this embodiment, the number and arrangement of the temperature sensors, as well as the setting of the target threshold in the accommodating chamber can be adaptively adjusted according to the use requirements. In order to improve the temperature regulation effect in the accommodating chamber, a connecting hole 10 can be provided on the storage box 4, and the connecting hole 10 connects the storage chamber 100 with the accommodating chamber. The connecting hole 10 here can be set on the side walls on both sides of the storage box 4, and on the end surface at one end of the accommodating chamber. In specific implementation, the position and number of the connecting holes can be determined according to the requirements.

[0056] In addition, the regulating unit in this embodiment may also include a humidifier and / or a dehumidifier capable of regulating the humidity in the accommodating chamber. That is to say, the regulating unit may only include a humidifier, in which case the regulating unit can only increase the humidity in the accommodating chamber. Alternatively, the regulating unit only includes a dehumidifier, in which case the regulating unit can only reduce the humidity in the accommodating chamber. Alternatively, the regulating unit includes a humidifier and a dehumidifier, in which case the regulating unit can not only increase the humidity in the accommodating chamber, but also reduce the humidity in the accommodating chamber. In specific implementation, the humidifier and the dehumidifier can be selectively arranged according to the use requirements.

[0057] Specifically, both the humidifier and the dehumidifier can be products in the prior art. The humidifier is preferably an ultrasonic humidifier, which atomizes water into extremely fine particles through ultrasonic high-frequency vibration, and then sends the water mist out through a fan. The dehumidifier sucks the humid air in the receiving chamber into the machine, and discharges dry air after treatment. In the specific arrangement, the humidifier can be set at the outlet end of the exhaust pipe 13.

[0058] In this embodiment, a humidity sensor for detecting humidity parameters in the accommodating cavity is further provided in the accommodating cavity. Specifically, when the humidity detected by the humidity sensor is lower than the target humidity threshold, the humidifier needs to be started so that the airflow blows the atomized water mist into the accommodating cavity, and the airflow flows into each storage cavity 100 through the gap between the frame and the storage box 4, thereby increasing the humidity in the accommodating cavity to within the target threshold range.

[0059] When the humidity detected by the humidity sensor is higher than the target humidity threshold, the dehumidifier needs to be started to discharge the air in the receiving chamber and discharge it to the air inlet after dehumidification processing by the dehumidifier, thereby reducing the humidity in the receiving chamber to within the target threshold range.

[0060] In this embodiment, the number and arrangement of humidity sensors, as well as the setting of the target humidity threshold in the receiving chamber can be adaptively adjusted according to the use requirements. It should be noted that in this embodiment, it is also feasible to only set up a humidifier or a dehumidifier. For example, in the case of only setting up a humidifier, the airflow in the receiving chamber is directly discharged through the exhaust pipe 13, which is also conducive to reducing the humidity in the receiving chamber.

[0061] In this embodiment, a control system may also be provided, and the control system is electrically connected to the temperature sensor, humidity sensor, heating module, cooling module, humidifier and dehumidifier, so as to realize intelligent adjustment of the environmental parameters in the receiving chamber, and the above-mentioned temperature target threshold and humidity target threshold are stored in the control system. The control system receives the temperature and humidity values ​​detected by the temperature sensor and the humidity sensor, and compares the temperature value of the receiving chamber with the temperature target threshold, and adjusts the working mode of the cooling module and the heating module according to the comparison result. At the same time, the humidity value of the receiving chamber can also be compared with the target humidity threshold, so as to adjust the working state of the humidifier and the dehumidifier.

[0062] The control system receives the temperature and humidity values ​​detected by the humidity sensor and the humidity sensor, and compares the temperature value of the receiving chamber with the temperature target threshold, thereby adjusting the working states of the refrigeration module, heating module, humidifier and dehumidifier according to the comparison result, so that the temperature and humidity in the receiving chamber are in a suitable environment, which is beneficial to improve the performance of the fuel cell preparation material.

[0063] In addition, the control system in this embodiment can also be connected to an external terminal, such as a host computer or a mobile phone, so as to facilitate the management personnel or the temperature and humidity information in the storage device for fuel cell preparation. In specific implementation, an alarm device electrically connected to the control system can also be provided. When at least one of the temperature and humidity in the accommodating chamber is abnormal, the alarm device can be activated to alert the management personnel to check the status of the storage device for fuel cell preparation. The alarm device here can be an audible and visual alarm in the prior art, which is simple in product, easy to arrange and implement, and has a good warning effect.

[0064] As a preferred embodiment, in this embodiment, a running wheel 3 is provided at the bottom of the cabinet 1. The running wheels 3 are arranged at intervals at the bottom of the cabinet 1, and the structure is simple, easy to arrange and implement, and conducive to improving the convenience of moving the storage device for fuel cell preparation. The running wheel 3 can adopt the running wheel 3 with a brake structure in the prior art to fix the position of the cabinet 1 after the cabinet 1 moves to the target position.

[0065] In addition, at least one side of the cabinet 1 is provided with a push-pull rod 2, which is used to operate the cabinet 1 to move. The push-pull rod 2 is preferably in a "U" shape, and can be arranged on the left and right sides of the cabinet 1, so that the push-pull rod 2 can be held by hand to apply external force to the cabinet 1, thereby improving the convenience of moving the storage device for fuel cell preparation. Of course, in specific implementation, the arrangement position and shape of the push-pull rod 2 can also be adaptively adjusted according to the use requirements.

[0066] The storage device for fuel cell preparation in this embodiment not only has a simple structure and is convenient for taking and placing fuel cell preparation materials, but can also adjust the temperature and humidity in the storage chamber to an appropriate range, thereby helping to improve the performance and safety of fuel cell preparation materials.
