[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0030] The embodiments of the present application provide a gas supply method and device, which will be described in detail below.

[0031] The gas supply device can be integrated into an electronic device, such as a terminal, a server, or a smart car. The terminal can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop computer, or a personal computer (PC); the server can be a single server or a server cluster consisting of multiple servers.

[0032] For example, see Figure 1 , shows a schematic diagram of an application scenario of the gas supply method, wherein the application scenario may include a fuel cell 101 and an electronic device 102, the fuel cell 101 may include a manifold and a plurality of single cells, the manifold is provided with two air inlets opposite to each other, and the gas supplied to the manifold by the two air inlets forms a gas intersection position, the electronic device 102 can detect the voltage of each single cell in the fuel cell 101; determine the gas deficiency position in the manifold according to the voltage of each single cell; and adjust at least one of the flow parameter and the air pressure parameter of the corresponding air inlet through the valve of the manifold in the fuel cell 101 to move the gas intersection position toward the gas deficiency position.

[0033] The following are detailed descriptions of each.

[0034] In this embodiment, a gas supply method is provided, such as Figure 2 As shown, the specific process of the gas supply method can be as follows:

[0035] S110 , detecting the voltage of each single battery.

[0036] A fuel cell can include multiple stacked cells. A manifold is a gas channel formed in the hollow portion of a cell. The manifold is provided with two opposing inlets for supplying gas to the manifold. The gases supplied by the two inlets can intersect within the manifold to form a gas intersection. Each inlet is provided with a corresponding valve, which can adjust at least one of the flow rate parameter and pressure parameter of the corresponding inlet. For example, see Figure 3 , showing a schematic structural diagram of a fuel cell.

[0037] The individual cells react with the gas supplied from the gas inlet to generate electricity. In some embodiments, the voltage of each individual cell in the fuel cell can indicate the reaction status of the cell. For example, when the cell is in sufficient contact with the gas, the reaction is good, and the voltage generated by the cell is within a certain range. Thus, the voltage of each individual cell in the fuel cell can be measured to determine the reaction status of the cell.

[0038] In some embodiments, when detecting the voltage of each single cell, a detection point may be pre-set on each single cell, and the voltage of each single cell may be detected by performing voltage detection on the detection point.

[0039] In some embodiments, the voltage of each single cell may be detected at a preset time interval. For example, if the preset time interval is set to 0.2s, the voltage of each single cell may be detected once every 0.2s. For another example, if the preset time interval is set to 0.1s, the voltage of each single cell may be measured once every 0.1s.

[0040] S120 : Determine the gas deficiency location according to the voltage of each single battery.

[0041] If the gas supply to a cell is sufficient, the reaction is good, and the voltage of the cell is within a certain range. Conversely, if the gas supply to a cell is insufficient, the reaction is poor, and the voltage of the cell is outside the range. Therefore, after obtaining the voltage of each cell, the location of the gas-deficient cell can be determined based on the voltage of each cell, thereby obtaining the corresponding gas-deficient location.

[0042] In some embodiments, the gas deficiency position may refer to the position corresponding to a single cell in the manifold. When determining the gas deficiency position based on the voltage of each single cell, the single cell whose voltage is within a first preset voltage range may be determined as a candidate single cell; the candidate single cell with the smallest voltage among the candidate single cells may be determined as a target single cell; and the position corresponding to the target single cell among the multiple positions of the manifold may be determined as the gas deficiency position.

[0043] The first preset voltage range refers to a pre-set voltage range that can be used to characterize the voltage of a single cell when the cell's reaction is poor. As an implementation, the voltage range within which a single cell's reaction is good can be empirically determined, denoted as the designated voltage range, and the first preset voltage range determined based on the designated voltage range. For example, if the voltage range for a single cell's good reaction is a2-a3, where a3 is greater than a2, then the first preset voltage range can be 0-a2.

[0044] Therefore, after obtaining the voltage of each cell, cells with voltages within a first preset voltage range can be identified as candidate cells. In other words, candidate cells are cells with poor response. After determining the candidate cells, the cell with the lowest voltage among the candidate cells can also be identified as the target cell.

[0045] For example, if there are three candidate cells with voltages b1, b2, and b3, where b1 is less than b2 and b2 is less than b3, the cell with voltage b1 among the candidate cells can be directly identified as the target cell. Since the manifold is a gas channel formed by the hollow portion of the cell, each position in the manifold corresponds to a cell. Therefore, the position on the manifold that corresponds to the target cell can be identified as the gas-deficient position.

[0046] In some embodiments, the gas deficiency position may refer to the corresponding positions of multiple single cells in the manifold. When determining the gas deficiency position in the manifold based on the voltage of each single cell, the single cell whose voltage is within a first preset voltage range may be determined as a candidate single cell; and the position corresponding to each candidate single cell among the multiple positions of the manifold is determined, thereby obtaining multiple gas deficiency positions.

[0047] As mentioned above, the candidate cells are cells with poor response, and multiple gas-deficient locations can be determined for each candidate cell. For example, the location corresponding to each candidate cell among multiple locations on the manifold can be determined as the gas-deficient location.

[0048] S130. Adjust at least one of the flow parameter and the air pressure parameter of the corresponding air inlet through the valve to move the gas intersection position toward the air-deficient position.

[0049] Each of the two opposing air inlets is provided with a corresponding valve, wherein the valve can adjust at least one of a flow rate parameter and a pressure parameter of the corresponding air inlet. For example, the valve can adjust the flow rate of the gas supplied to the corresponding air inlet, the valve can also adjust the pressure of the gas supplied to the corresponding air inlet, or the valve can simultaneously adjust the flow rate and pressure of the gas supplied to the air inlet.

[0050] When the manifold size is constant, if the air pressure at the air inlet remains unchanged, the greater the gas flow rate and flow velocity, the greater the pressure generated. When the gas flow rate remains unchanged, the greater the gas pressure, the greater the pressure generated.

[0051] When only one air-deficient position is determined, at least one of the flow parameter and the air pressure parameter of the corresponding air inlet is adjusted by the valve to move the gas intersection position toward the air-deficient position, which can be done by determining the direction from the gas intersection position to the air-deficient position as the target direction; increasing the opening of the valve corresponding to the air inlet whose outlet direction is consistent with the target direction to increase at least one of the flow parameter and the air pressure parameter of the air inlet; or reducing the opening of the valve corresponding to the air inlet whose outlet direction is opposite to the target direction to reduce at least one of the flow parameter and the air pressure parameter of the air inlet.

[0052] In order to move the gas intersection position toward the gas deficiency position, the direction from the gas intersection position to the gas deficiency position can be determined as the target direction, and then the gas intersection position can be directly controlled to move toward the target direction. Each gas inlet has a corresponding gas outlet direction, which refers to the flow direction of the gas entering the manifold from the gas inlet. For example, you can continue to refer to Figure 3 , the upper air inlet is marked as air inlet 1, and the other air inlet is marked as air inlet 2. The outlet direction of air inlet 1 is from air inlet 1 to air inlet 2, and the outlet direction of air inlet 2 is from air inlet 2 to air inlet 1.

[0053] When controlling the gas intersection position to move to the gas-deficient position, the valve opening corresponding to the gas inlet whose outlet direction coincides with the target direction may be increased to increase at least one of the flow rate parameter and the pressure parameter of the gas inlet. For example, if the target direction is from gas inlet 1 to gas inlet 2, i.e., downward, since a larger valve opening increases the flow rate or pressure of the gas supplied from the gas inlet, in order to control the gas intersection position to move downward, the valve opening of gas inlet 1 may be adjusted to increase the flow rate or pressure of the gas supplied from gas inlet 1, thereby controlling the gas intersection position to move downward.

[0054] In some embodiments, the valve opening corresponding to the inlet whose outlet direction is opposite to the target direction can be reduced to reduce at least one of the flow rate parameter and the pressure parameter of the inlet. For example, if the target direction is from inlet 1 to inlet 2, and the inlet whose outlet direction is opposite to the target direction is inlet 2, the valve opening of inlet 2 can be reduced to reduce the flow rate or pressure of the gas supplied by inlet 2, thereby controlling the downward movement of the gas intersection point.

[0055] In some embodiments, the valve of the air inlet may include a flow valve and an air pressure valve. The flow valve can be used to adjust the flow parameters of the air inlet. The larger the opening of the flow valve, the greater the flow rate of the gas supplied by the air inlet; the air pressure valve can be used to adjust the air pressure parameters of the air inlet. The larger the opening of the air pressure valve, the greater the air pressure of the gas supplied by the air inlet.

[0056] Of course, in some embodiments, if the valve opening of an inlet whose outlet direction aligns with the target direction reaches its maximum, the flow rate or pressure of the gas supplied from that inlet cannot be further increased, and the valve opening of another inlet can be reduced. Similarly, if the valve opening of an inlet whose outlet direction is opposite to the target direction reaches its minimum, the flow rate or pressure of the gas supplied from that inlet cannot be further reduced, and the valve opening of another inlet can be increased.

[0057] After controlling the gas intersection position to move to the gas deficiency position, the gas deficiency position can be further determined so as to control the movement of the gas intersection position again to adapt to the gas demand of the single cells at different positions in the fuel cell and ensure the efficient operation of the fuel cell.

[0058] When there are multiple gas-deficient positions determined, at least one of the flow parameters and air pressure parameters of the corresponding air inlet is adjusted by the valve to move the gas intersection position toward the gas-deficient position, the number of gas-deficient positions corresponding to each area in the two side areas of the gas intersection position can be obtained; the direction from the gas intersection position to the target area is determined as the sorting direction, and the target area is the area with a larger number of gas-deficient positions in the two side areas; with the gas intersection position as the starting point, the arrangement order of the multiple gas-deficient positions in the sorting direction is determined; at least one of the flow parameters and air pressure parameters of the corresponding air inlet is adjusted by the valve to move the gas intersection position toward the gas-deficient position in sequence according to the arrangement order.

[0059] Since multiple gas-deficient positions are determined, in order to move the gas intersection position to multiple gas-deficient positions, the area within the manifold can be divided into two areas with the gas intersection position as the dividing line, namely the areas on both sides of the gas intersection position, and then the number of corresponding gas-deficient positions in each area can be obtained.

[0060] For example, see Figure 4 , showing the positional relationship between the gas deficiency position and the gas intersection position, Figure 4 In the figure, the dotted line represents the gas deficiency position, and the solid line represents the gas intersection position. There are three gas deficiency positions in total, which are recorded as gas deficiency position 1, gas deficiency position 2 and gas deficiency position 3. Gas deficiency position 1 and gas deficiency position 2 are located on the same side of the gas intersection position, that is, area 1, and gas deficiency position 3 is located on the other side of the gas intersection position, that is, area 2. It can be seen that in the areas on both sides of the gas intersection position, the number of gas deficiency positions in area 1 is 2, and the number of gas deficiency positions in area 2 is 1, so area 1 can be determined as the target area. In other words, the target area refers to the area on both sides of the gas intersection position where there are more gas deficiency positions.

[0061] The direction from the gas intersection position to the target area is then determined as the sorting direction for subsequent determination of the arrangement order of multiple gas-deficient positions.

[0062] In some embodiments, if the number of gas-deficient positions corresponding to each area on both sides of the gas intersection position is the same, the gas-deficient position closest to the gas intersection position is determined as the target gas-deficient position; and the direction from the gas intersection position to the target gas-deficient position is determined as the sorting direction.

[0063] In some embodiments, if the number of gas-deficient locations corresponding to each of the regions on either side of the gas intersection is the same, the distance between each gas-deficient location and the gas intersection can be further obtained to determine the gas-deficient location closest to the gas intersection and record this gas-deficient location as the target gas-deficient location. The direction from the gas intersection to the target gas-deficient location is then determined as the sorting direction, and the order of the multiple gas-deficient locations is determined based on the sorting direction.

[0064] In some embodiments, when determining the arrangement order of multiple gas-deficient positions in the sorting direction with the gas intersection position as the starting point, the distance that the gas intersection position moves to the gas-deficient position in the sorting direction can be determined with the gas intersection position as the starting point, as the target distance corresponding to the gas-deficient position, and the sorting order of the multiple gas-deficient positions in the sorting direction is determined based on the target distance.

[0065] For example, it can be determined whether the gas intersection position can be moved to the corresponding gas-deficient position in the sorting direction; if so, the distance between the gas-deficient position and the gas intersection position is used as the corresponding target distance; if not, the sum of the preset distance and the distance between the gas-deficient position and the gas intersection position is used as the corresponding target distance. For example, in the above example, if the distance between the gas intersection position and gas-deficient position 1 is 2 cm, the distance between the gas intersection position and gas-deficient position 1 is 2 cm, the distance between the gas intersection position and gas-deficient position 3 is 1 cm, and the preset distance is 5 cm, since the gas intersection position cannot be moved to gas-deficient position 3 in the sorting direction, the target distance corresponding to gas-deficient position 1 is 2 cm, the target distance corresponding to gas-deficient position 2 is 1 cm, and the target distance corresponding to gas-deficient position 3 is 5+1=6 cm, then the sorting order is gas-deficient position 2, gas-deficient position 1, and gas-deficient position 3.

[0066] Then, at least one of the flow rate parameter and the air pressure parameter of the corresponding air inlet is adjusted by the valve so that the gas intersection position moves toward the air deficiency position in the order of arrangement. That is, the gas intersection position is controlled to move to air deficiency position 2, air deficiency position 1, and air deficiency position 3 in sequence.

[0067] If the gas intersection position is first controlled to move to the gas-deficient position 2, the valve opening of the gas inlet 2 can be increased to increase the flow rate or pressure of the gas supplied by the gas inlet 2; or the valve opening of the gas inlet 1 can be decreased to decrease the flow rate or pressure of the gas supplied by the gas inlet 1. In this way, the gas intersection position can be controlled to move from the gas-deficient position 2 to the gas-deficient position 1.

[0068] When it is necessary to control the gas intersection position to move from the gas-deficient position 2 to the gas-deficient position 3, the valve opening of the air inlet 1 can be increased to increase the flow rate or pressure of the gas supplied by the air inlet 1; or the valve opening of the air inlet 2 can be reduced to reduce the flow rate or pressure of the gas supplied by the air inlet 2.

[0069] The gas supply solution provided in the embodiments of the present application can be applied to various fuel cell gas supply scenarios. For example, taking the gas supply of a fuel cell as an example, the solution provided in the embodiments of the present application can intelligently detect cells with poor reactions and thereby determine the gas deficiency location. Then, by adjusting the valve, at least one of the flow rate parameter and pressure parameter corresponding to the gas inlet is adjusted to move the gas intersection formed by the gas supplied by the two gas inlets to the gas deficiency location, thereby improving the reaction of the cells at the gas deficiency location and adapting to the gas flow and flow rate requirements of cells at different locations, thereby ensuring the efficient operation of the fuel cell.

[0070] The method provided in the embodiments of the present application can detect the voltage of each single cell; determine the gas deficiency location based on the voltage of each single cell; and adjust at least one of the flow rate parameter and air pressure parameter of the corresponding air inlet through a valve to move the gas intersection location toward the gas deficiency location. The gas deficiency location can be intelligently determined based on the voltage of the single cell, and at least one of the corresponding flow rate parameter and air pressure parameter can be adjusted through the air inlet to move the gas intersection location formed by the gas supplied by the two air inlets to the gas deficiency location, thereby improving the reaction of the single cell at the gas deficiency location and adapting to the gas flow and flow rate requirements of single cells at different locations, thereby ensuring the efficient operation of the fuel cell.

[0071] In this embodiment, a gas supply method is provided, such as Figure 5 As shown, the specific process of the gas supply method can be as follows:

[0072] S210 , obtaining the maximum value and the minimum value corresponding to the flow parameter and the pressure parameter of the air inlet, respectively.

[0073] The flow parameters and air pressure parameters of the air inlet can be adjusted through the valve of the air inlet. It can be understood that the flow parameters and air pressure parameters of the air inlet will not increase or decrease infinitely. Therefore, the maximum and minimum values ​​of the flow parameters of the air inlet and the maximum and minimum values ​​of the air pressure parameters can be obtained first.

[0074] As an embodiment, the valve at the air inlet may include a pressure valve and a flow valve; if the pressure valve is fully opened, the pressure parameter at the air inlet reaches a maximum value; if the pressure valve is fully opened, the flow parameter at the air inlet reaches a minimum value. If the flow valve is fully opened, the flow parameter at the air inlet reaches a maximum value; if the flow valve is fully opened, the flow parameter at the air inlet reaches a minimum value.

[0075] Therefore, the openings of the pressure valve and flow valve at the air inlet can be adjusted to the maximum to obtain the maximum values ​​of the pressure parameters and flow parameters; the openings of the pressure valve and flow valve at the air inlet can be adjusted to the minimum to obtain the minimum values ​​of the pressure parameters and flow parameters.

[0076] S220. Adjust the valve opening so that at least one of the flow parameter and the air pressure parameter of one air inlet changes from the maximum value to the minimum value, and at least one of the flow parameter and the air pressure parameter of the other air inlet changes from the minimum value to the maximum value.

[0077] In order to change at least one of the flow parameter and the air pressure parameter of one air inlet from a maximum value to a minimum value, and at least one of the flow parameter and the air pressure parameter of the other air inlet from a minimum value to a maximum value, a preset interval and a preset opening degree may be obtained; each time the preset interval passes, the valve opening degree is controlled to decrease the preset opening degree so that at least one of the flow parameter and the air pressure parameter of the one air inlet changes from the maximum value to the minimum value; and each time the preset interval passes, the valve opening degree is controlled to increase the preset opening degree so that at least one of the flow parameter and the air pressure parameter of the other air inlet changes from the minimum value to the maximum value.

[0078] Among them, the preset interval is a preset time interval, which can be set according to actual needs and is not specifically limited here. The preset opening refers to the preset valve opening of the air inlet, which can also be set according to actual needs and is not specifically limited here.

[0079] In order to make at least one of the pressure parameters and flow parameters of one air inlet reach the maximum value and at least one of the pressure parameters and flow parameters of the other air inlet reach the minimum value, the valve opening of one air inlet can be adjusted to the maximum and the valve opening of the other air inlet can be adjusted to the minimum.

[0080] Then, every time a preset interval passes, the valve opening of one air inlet can be controlled to decrease the preset opening, so that at least one of the flow parameter and the air pressure parameter of the air inlet changes from a maximum value to a minimum value; every time a preset interval passes, the valve opening of one air inlet can be controlled to increase the preset opening, so that at least one of the flow parameter and the air pressure parameter of the air inlet changes from a minimum value to a maximum value.

[0081] In some embodiments, only the flow parameter of the air inlet can be adjusted, while the pressure parameter remains unchanged. Similarly, if only the pressure parameter of the air inlet is adjusted, the flow parameter can be kept unchanged. For example, if the two air inlets are a first air inlet and a second air inlet, the valve opening of the first air inlet can be adjusted to the maximum so that the flow parameter of the first air inlet is the maximum value, and the valve opening of the second air inlet can be adjusted to the minimum so that the pressure parameter of the second air inlet is the minimum value. After each preset interval, the valve opening of the first air inlet is reduced by a preset opening, and the valve opening of the second air inlet is increased by a preset opening, so that the gas intersection position formed by the gases supplied by the two air inlets can be moved from the first air inlet to the second air inlet.

[0082] In some embodiments, the flow parameters and pressure parameters of the air inlet may be adjusted simultaneously. For example, the larger the valve opening, the larger the flow parameters and pressure parameters of the air inlet, and the smaller the valve opening, the smaller the flow parameters and pressure parameters of the air inlet.

[0083] For example, if there are two air inlets, namely a first air inlet and a second air inlet, the valve opening of the first air inlet can be adjusted to a maximum value, while the valve opening of the second air inlet can be adjusted to a minimum value. At every preset interval, the valve opening of the first air inlet is reduced by a preset value, thereby reducing the flow rate and pressure parameters of the first air inlet, and the valve opening of the second air inlet is increased by a preset value, thereby increasing the flow rate and pressure parameters of the second air inlet.

[0084] According to the above method, the gas intersection position can be moved from top to bottom, or from bottom to top, to pass through single cells at different positions. Since the gas flow rate at the gas intersection position is relatively large, the corresponding single cells can be purged to prevent foreign matter on the single cells from affecting the reaction effect of the fuel cell, thereby ensuring the efficient operation of the fuel cell.

[0085] To better implement the above method, the present application also provides a gas supply device. The gas supply device can be integrated into an electronic device, such as a terminal or a server. The terminal can be a mobile phone, tablet computer, smart Bluetooth device, laptop computer, personal computer, etc. The server can be a single server or a server cluster consisting of multiple servers.

[0086] For example, in this embodiment, the method of the embodiment of the present application will be described in detail by taking the specific integration of the gas supply device into an electronic device as an example.

[0087] For example, Figure 6 As shown, the gas supply device may include a detection module 310 , a determination module 320 and an adjustment module 330 .

[0088] A detection module 310 is used to detect the voltage of each single battery;

[0090] The regulating module 330 is configured to regulate at least one of a flow parameter and a pressure parameter of the corresponding air inlet through the valve, so as to move the gas intersection position toward the gas-deficient position.

[0091] In some embodiments, the determination module 320 is further configured to:

[0092] Determine the single battery cells whose voltages are within the first preset voltage range as candidate single batteries;

[0093] Determine the candidate single cell with the smallest voltage among the candidate single cells as the target single cell;

[0094] A position corresponding to the target single cell among a plurality of positions of the manifold is determined as the gas deficiency position.

[0095] In some embodiments, the adjustment module 330 is further configured to:

[0096] determining a direction from the gas intersection position to the gas deficiency position as a target direction;

[0097] increasing the opening of a valve corresponding to an air inlet whose air outlet direction is consistent with the target direction, so as to increase at least one of a flow parameter and an air pressure parameter of the air inlet;

[0098] Alternatively, the opening of the valve corresponding to the air inlet whose air outlet direction is opposite to the target direction is reduced to reduce at least one of the flow parameter and the air pressure parameter of the air inlet.

[0099] In some embodiments, the determination module 320 is further configured to:

[0100] Determine the single battery cells whose voltages are within the first preset voltage range as candidate single batteries;

[0101] A position corresponding to each of the candidate single cells is determined among a plurality of positions of the manifold, thereby obtaining a plurality of gas deficiency positions.

[0102] In some embodiments, the adjustment module 330 is further configured to:

[0103] Obtaining the number of gas-deficient positions corresponding to each area on both sides of the gas intersection position;

[0104] Determine the direction from the gas intersection position to the target area as the sorting direction, and the target area is the area with a larger number of gas-deficient positions in the two side areas;

[0105] Taking the gas intersection position as a starting point, determining an arrangement order of the plurality of gas-deficient positions in the sorting direction;

[0106] At least one of the flow parameter and the air pressure parameter of the corresponding air inlet is adjusted by the valve so that the gas intersection position moves toward the air-deficient position in sequence according to the arrangement order.

[0107] In some embodiments, before determining the arrangement order of the plurality of gas-deficient positions in the sorting direction with the gas intersection position as the starting point, the adjustment module 330 is further configured to:

[0108] If the number of gas-deficient positions corresponding to each area on both sides of the gas intersection position is the same, the gas-deficient position closest to the gas intersection position is determined as the target gas-deficient position;

[0109] The direction from the gas intersection position to the target gas deficiency position is determined as the sorting direction.

[0110] During specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined and implemented as the same or several entities. The specific implementation of the above modules can be found in the previous method embodiments and will not be repeated here.

[0111] As can be seen from the above, the gas supply device of this embodiment can detect the voltage of each single cell; determine the gas deficiency location based on the voltage of each single cell; and adjust at least one of the flow rate parameter and the air pressure parameter of the corresponding air inlet through a valve to move the gas intersection point toward the gas deficiency location. The gas deficiency location can be intelligently determined based on the voltage of the single cell, and at least one of the corresponding flow rate parameter and air pressure parameter can be adjusted through the air inlet to move the gas intersection point formed by the gas supplied by the two air inlets to the gas deficiency location. This improves the reaction of the single cell at the gas deficiency location, adapts to the gas flow and flow rate requirements of the single cells in different locations, and thus ensures the efficient operation of the fuel cell.

[0112] To better implement the above method, the present application also provides a gas supply device. The gas supply device can be integrated into an electronic device, such as a terminal or a server. The terminal can be a mobile phone, tablet computer, smart Bluetooth device, laptop computer, personal computer, etc. The server can be a single server or a server cluster consisting of multiple servers.

[0113] For example, in this embodiment, the method of the embodiment of the present application will be described in detail by taking the specific integration of the gas supply device into an electronic device as an example.

[0114] For example, Figure 7 As shown, the gas supply device may include an acquisition module 410 and a control module 420 .

[0115] An acquisition module 410 is configured to acquire the maximum and minimum values ​​of the flow rate parameter and the pressure parameter of the air inlet, respectively;

[0116] The control module 420 is used to adjust the valve opening so that at least one of the flow parameter and the air pressure parameter of one air inlet changes from the maximum value to the minimum value, and at least one of the flow parameter and the air pressure parameter of the other air inlet changes from the minimum value to the maximum value, so that the gas intersection position moves within the manifold.

[0117] In some embodiments, the control module 420 is further configured to:

[0118] Get the preset interval and preset opening;

[0119] Every time the preset interval passes, controlling the valve opening to reduce the preset opening, so that at least one of the flow parameter and the air pressure parameter of an air inlet changes from the maximum value to the minimum value;

[0120] Every time the preset interval passes, the valve opening is controlled to increase the preset opening, so that at least one of the flow parameter and the air pressure parameter of the other air inlet changes from the minimum value to the maximum value.

[0121] Therefore, the embodiment of the present application can move the gas intersection position from top to bottom, or from bottom to top, to pass through single cells at different positions. Since the gas flow rate at the gas intersection position is relatively large, the corresponding single cells can be purged to prevent foreign matter on the single cells from affecting the reaction effect of the fuel cell, thereby ensuring the efficient operation of the fuel cell.
