In other embodiments, the collection unit includes but is not limited to a flow meter, where the working parameter information includes a water production amount of the fuel cell, and the vaporization latent heat condition includes that the water production amount of the fuel cell reaches a predetermined level. The set water production threshold. For example, a threshold is set in the control unit in advance, the control unit is electrically connected to the flow meter, and when the water production is greater than the threshold, the latent heat exchange device is controlled to work (for example, the outlet check valve is controlled to open); when the water production is less than the threshold, the Control the latent heat exchange device to be inoperative (eg, close the outlet check valve). When the fuel cell is working, the internal electrochemical reaction generates water at all times. The greater the output power of the fuel cell, the greater the amount of electrochemical reaction, and the more water generated. Therefore, the latent heat exchange device can be controlled according to the water generated by the electrochemical reaction. working status. Of course, those skilled in the art can understand that the above-mentioned acquisition unit, working parameter information, and latent heat of vaporization conditions are only examples, and other existing or possible acquisition units, working parameter information, and latent heat of vaporization conditions that can be applied to This embodiment is also within the protection scope of this embodiment, and is incorporated herein by reference. For example, the acquisition unit also includes the temperature sensor and the flow meter, and when the operating temperature of the fuel cell reaches a temperature threshold and the water production volume of the fuel cell reaches a preset water production volume threshold at the same time, the heat exchange device At least one outlet check valve between the water storage tank and the latent heat of vaporization device is controlled to be opened by the control unit, so that the latent heat of vaporization device can vaporize the water stored in the water storage tank and utilize the stored water the latent heat of vaporization to cool down. In some embodiments, the control unit includes but is not limited to a single-chip microcomputer. In some embodiments, a small amount of water is pre-stored in the water storage tank 1 for use when the water generated by the fuel cell 4 is too small to meet the cooling requirement. In this embodiment, at least one outlet check valve is set between the latent heat of vaporization device and the water storage tank 1, only when the working parameter information about the fuel cell collected by the collecting unit satisfies the latent heat of vaporization condition , the control unit controls the opening of the outlet check valve, so that the latent heat of vaporization device can vaporize the water stored in the water storage tank 1 and use the latent heat of vaporization of the stored water to cool down; When the parameter information does not satisfy the latent heat of vaporization condition, the outlet check valve between the water storage tank 1 and the latent heat of vaporization device is in a closed state. On the one hand, the water stored in the water storage tank 1 can be used sparingly; on the other hand, sufficient time can be given to the water received by the water storage tank 1 and generated by the fuel cell, so that the water received by the water storage tank 1 can be cooled sufficiently to generate water, and make the entire heat exchange device automatically switch between different working states (for example, general heat dissipation state and high-efficiency heat dissipation state).

In some embodiments, as shown in FIG. 4 and FIG. 5 , the water storage tank 1 includes a plurality of water storage rooms (for example, the water storage room 11 and the water storage room 11 ′ shown in FIG. 4 and FIG. 5 , of course, this Those skilled in the art can understand that Figures 4 and 5 are only examples, and the water storage tank 1 may also include three, four or more water storage rooms), and each water storage room in the plurality of water storage rooms The outlet check valve (for example, the outlet check valve 7 and the outlet check valve 7 ′ shown in FIG. 4 and FIG. 5 ) are respectively provided between the device and the vaporization latent heat device. In some embodiments, when the water storage tank 1 includes a plurality of water storage rooms, and the outlet check valve is respectively provided between each water storage room and the vaporization latent heat device, the heat exchange device The control unit can individually control the on-off state of the outlet check valve of one or several water storage rooms, so that the latent heat of vaporization device can use the water stored in one or several water storage rooms correspondingly. For example, as shown in FIG. 4 , the water generated by the fuel cell 4 during operation is shunted to the corresponding water storage rooms 11 and 11 ′ through different pipes. When the working parameter information of the fuel cell 4 satisfies the vaporization In the latent heat condition, the control unit can randomly control the outlet check valve corresponding to one of the water storage rooms (for example, the outlet check valve 7 corresponding to the water storage room 11), or it can open the corresponding single water storage rooms in sequence from left to right. (for example, open the outlet check valve 7 first, and then open the outlet check valve 7' after a certain period of time). For another example, as shown in FIG. 5 , the water generated by the fuel cell 4 during operation flows to the water storage tank 1 through the same pipeline, and the water storage tank 1 is separated by the partitions 12 to form a plurality of water storage rooms (for example, FIG. 5 The water storage room 11 and the water storage room 11 ′ are shown, of course, those skilled in the art can understand that three, four or more water storage rooms can also be included), and the height of the partition 12 is smaller than the height of the water storage tank 1 height, so that a certain gap 13 is left between the top of the partition plate 12 and the top plate of the water storage tank 1. When the water in a certain water storage room (for example, the water storage room 11) is full, it can flow in through the gap 13. In another water storage room (for example, the water storage room 11') adjacent to the water storage room. In some embodiments, referring to FIG. 5 , when the water generated by the fuel cell 4 during operation flows into the water storage tank 1 through the same pipe, the pipe can be arranged in the leftmost or rightmost water storage room of the water storage tank, In order to fill the storage compartments sequentially from left to right or right to left. Of course, those skilled in the art can understand that the pipeline can also be arranged in any water storage room, and when the water storage room is full, it will overflow into one or two water storage rooms adjacent to the water storage room. When the working parameter information of the fuel cell 4 satisfies the latent heat of vaporization condition, the control unit can randomly control the opening of the outlet check valve 7 corresponding to one of the water storage rooms, or control the opening of the outlet check valve 7 corresponding to the leftmost water storage room 11. To the valve 7 (for example, as shown in FIG. 5, when the water generated by the fuel cell 4 flows into the water storage tank 1 through the same pipeline, the pipeline is arranged in the water storage room on the far left of the water storage tank), or control the Open the outlet check valve 7 corresponding to the leftmost water storage room 11 , and the outlet check valve corresponding to any other one, or any multiple water storage rooms.

In some embodiments, at least one of the water storage rooms is installed with a water level sensing unit (not shown), the water level sensing unit is electrically connected with the control unit, and the control unit is further configured to sense the water level according to the water level sensing unit The detected water level information controls the switch state of the outlet check valve of the corresponding water storage room. For example, when the water storage tank includes a plurality of water storage rooms, and an outlet check valve is provided between each water storage room and the latent heat of vaporization device, if it is detected that the working parameter information of the fuel cell satisfies the latent heat of vaporization condition, the control unit may determine the outlet check valve of the corresponding water storage room according to the water level information detected by the water level sensing unit. In some embodiments, the water level sensing unit includes, but is not limited to, a water level sensor, a hydraulic pressure sensor, etc. The water level sensing unit disposed in the water storage room 11 is used to detect the water level information of the water storage room 11 so as to control the The unit controls the on/off state of the outlet check valve of the corresponding water storage room according to the water level information (for example, opens or closes the outlet check valve). In some embodiments, the water level sensing unit is installed in at least one of the water storage rooms. For example, in the water storage tank shown in FIG. 4 or FIG. 5 , the water level may be installed in each of the plurality of water storage rooms (for example, the water storage room 11, the water storage room 11'...) The sensing unit, when the working parameter information of the fuel cell 4 satisfies the latent heat of vaporization condition, the control unit determines at least one target water level information whose water level information is equal to or greater than the water level threshold according to the water level information detected by the plurality of water level sensing units, and converts all the water level information to the target water level information. The water storage room corresponding to the target water level information is used as the target water storage room, so as to control the opening of the outlet check valve of the target water storage room. In some embodiments, there may be multiple target water storage rooms whose water level information is equal to or greater than the water level threshold. When there are multiple target water storage rooms, the control unit may randomly control at least one target to be turned on. The outlet one-way valve of the water storage room can also be opened from left to right, or from right to left, to open the outlet one-way valve of at least one target water storage room in turn. In some embodiments, moisture is pre-stored in one of the water storage rooms, so that the pre-stored moisture can be used to perform the latent heat of vaporization when the latent heat of vaporization device is not sufficient to utilize the latent heat of vaporization of moisture generated by the fuel cell. When there is pre-stored moisture, and it is detected that multiple water level information reaches the target water storage time of the water level threshold, the outlet check valve of the pre-stored water storage room may be opened first. For another example, as shown in FIG. 5, the water storage tank can be installed in the water storage room 11' on the right side (in other words, in the water storage room for receiving and storing the water overflowing from other water storage rooms adjacent to it) The water level sensing unit is not provided in the water storage room 11 on the left side. When the working parameter information of the fuel cell 4 meets the latent heat of vaporization condition, the control unit senses the water level according to the water level. The water level information detected by the unit determines that only the outlet check valve of the left water storage room 11 is opened, or the outlet check valves of the left water storage room 11 and the right water storage room 11' are opened simultaneously. For example, when the water level information detected by the water level sensing unit is equal to or greater than the first water level threshold and less than the second water level threshold, the control unit only controls to open the outlet one-way valve of the left water storage room 11. When the water level information detected by the water level sensing unit is equal to or greater than the second water level threshold, the control unit controls to simultaneously open the outlet check valve of the left water storage room 11 and the outlet check valve of the right water storage room 11'. Valve 7'. In other embodiments, if the water level information of the water storage room with the outlet check valve in the open state is less than the water level threshold during the process that the working parameter information of the fuel cell 4 satisfies the vaporization latent heat condition, the control closes the The outlet check valve of the water storage room is controlled to open the outlet check valve of the next water storage room. In some embodiments, the water level information of the next water storage room is also equal to or greater than the water level threshold.

In some embodiments, at least one inlet check valve 8 is provided between the plurality of water storage rooms and the drainage unit of the fuel cell 4 , when the inlet check valve 8 is opened, the fuel cell 4 works The water produced in the process flows into the corresponding several water storage rooms among the plurality of corresponding water storage rooms through the inlet check valve 8 . For example, as shown in FIG. 4 , the plurality of water storage rooms share one inlet check valve 8 , or, as shown in FIG. 5 , the drain unit of the fuel cell 4 and the plurality of water storage rooms are connected by a pipeline, and the An inlet check valve 8 is arranged on the pipeline. For another example, as shown in FIG. 3 and FIG. 6 , an inlet check valve (eg, an inlet check valve) is provided between each water storage room (eg, the water storage room 11 , the water storage room 11 ′) and the drain unit of the fuel cell 4 . valve 8, inlet check valve 8'). Of course, those skilled in the art can understand that the arrangement of the inlet check valve 8 shown in FIG. 4 is also applicable to the embodiments corresponding to FIGS. 3 and 6 . The arrangement of the inlet check valve 8 shown in FIGS. 3 and 6 is also applicable to the embodiment corresponding to FIG. 4 . In some embodiments, when the water storage tank 1 includes multiple water storage rooms and at least one inlet check valve 8 is provided between the multiple water storage rooms and the drain unit of the fuel cell 4, the A control unit is electrically connected to each of the inlet check valves 8, so that the control unit automatically controls to open the corresponding inlet check valve. For example, the at least one inlet check valve is sequentially opened, so that the water generated by the fuel cell fills up the water storage rooms in sequence. Here, when the working parameter information of the fuel cell satisfies the latent heat of vaporization condition, the control unit may Control to open the first water storage room, or the first water storage room that is full of water (for example, each water storage room corresponds to an inlet one-way valve and an outlet one-way valve, when storing water, the control unit starts from the left Open at least one inlet one-way valve to the right or from right to left to store water. When the working parameter information meets the latent heat of vaporization condition, the control unit also opens at least one in sequence from left to right or right to left. Outlet one-way valve to allow the first stored, better-cooled moisture to vaporize latent heat first). For another example, the at least one inlet check valve is opened at the same time, so that the water produced by the fuel cell is collected in each water storage room at the same time. In this embodiment, by arranging an inlet check valve between the drain unit of the fuel cell 4 and the plurality of water storage rooms, the water generated during the operation of the fuel cell can be controlled to flow into the corresponding water storage rooms.

In some embodiments, the control unit is electrically connected to each of the inlet check valves, and the control unit is further configured to control the corresponding inlet check valve of the water storage room according to the water level information of the water storage room The switch status of the valve. For example, according to the water level information detected by the water level sensing unit disposed in the water storage room, the control unit controls to open the inlet check valve of the corresponding water storage room (for example, randomly or in a certain order (for example, Open the inlet check valve of at least one water storage room whose water level information is less than the preset threshold from left to right or from right to left; for another example, randomly or in a certain order (for example, from left to right or from right to right) Left) Open the inlet check valve of the water storage room with the water level information within a certain range, so as to concentrate the water storage room).

Under high-power conditions (for example, when the output power of the fuel cell 4 is greater than a certain power threshold), the output power of the fuel cell 4 increases, and the heat dissipation also increases sharply. Only through the cooperation between the heat dissipation unit 2 and the cooling unit 3 The heat dissipation requirement of the fuel cell 4 cannot be met, and the heat dissipation inside the fuel cell 4 is unbalanced. At this time, the heat exchange device automatically opens the outlet check valve 7 of the water storage tank 1 through the control unit, so that the latent heat of vaporization The water stored in the water storage tank 1 is vaporized, and the temperature is lowered by utilizing the latent heat of vaporization of the stored water at the air inlet of the heat dissipation unit. In this embodiment, the heat exchange device controls to open the outlet check valve 7 of the water storage tank 1 only when the fuel cell 4 needs to increase the heat dissipation efficiency of the heat dissipation unit 2 .

In other embodiments, it may also be determined whether the latent heat of vaporization condition is satisfied based on the working state of the fuel cell using carrier. For example, when the driver operates the fuel cell power system, the throttle valve (that is, the accelerator) is always passed by the driver, etc. Change the output power of the fuel cell. Therefore, the working state of the heat exchange device can be determined according to the operation mode of the driver.

The following description mainly takes the case where the latent heat of vaporization condition includes that the operating temperature of the fuel cell reaches a preset temperature threshold as an example. For example, the fuel cell 4 has different heat dissipation requirements under different operating conditions. For example, under normal operating conditions, the heat dissipation unit and the cooling unit can work together to meet the heat dissipation requirements of the fuel cell, and the interior of the fuel cell stack is in a state of heat dissipation balance. At this time, the temperature sensor shows that the temperature is within the normal range (for example, the fuel cell The working temperature of the fuel cell does not reach the temperature threshold), at this time, the latent heat of vaporization device does not work (for example, the outlet check valve 7 is in a closed state), and the moisture generated by the fuel cell is stored in the water storage tank 1, which can be fully carried out. of cooling. However, under high-power conditions, the output power of the fuel cell system increases, the heat dissipation rises sharply, and the combined operation of the heat dissipation unit and the cooling unit cannot meet the heat dissipation requirements. At this time, the internal heat dissipation of the fuel cell is unbalanced and the temperature rises. When the current operating temperature of the fuel cell reaches the temperature threshold, at least one outlet one-way valve is controlled to be opened. At this time, the latent heat of vaporization device starts to work to utilize the water in the water storage tank for latent heat of vaporization and reduce the air inlet of the cooling unit. the air temperature there. In some embodiments, the vaporization latent heat device includes, but is not limited to, a water distribution cooling unit.
