[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to solve the problem that the monitoring device in the prior art cannot monitor the water distribution and dynamic changes of water in the fuel cell manifold online, the present invention provides a fuel cell monitoring device, method and non-volatile storage medium.

[0025] Please refer to Figure 1 and Figure 2As described above, one aspect of the technical solution of the present invention provides a fuel cell monitoring device, including a plurality of insulating probe rods 10 and a plurality of camera components 11, at least a portion of each insulating probe rod 10 extends into the manifold of the battery stack 100 and is movably arranged, and each insulating probe rod 10 is rotatably arranged around its axis; the plurality of camera components 11 are respectively and one by one arranged on the outer peripheral walls of the plurality of insulating probe rods 10, so that when the insulating probe rods 10 move in the manifold, they drive the camera components 11 to obtain the distribution status of water and gas in the manifold.

[0026] One aspect of the technical solution of the present embodiment is to control the insulating probe rod 10 to move and rotate in the manifold so that the camera component 11 can obtain real-time images at different positions and angles, and by analyzing the real-time images obtained by the camera component 11, the distribution of water and gas and their dynamic changes can be accurately monitored, and the working conditions inside the battery stack 100 can be more intuitively understood, so that the monitoring system can promptly discover potential water management problems and accurately determine the location and extent of water management failures, such as flooding or membrane drying, thereby improving the stability and safety of the fuel cell system. The mobility and rotatability of the insulating probe rod 10 can not only adapt to fuel cell stacks 100 of different types and sizes, but also monitor potential fault points, thereby improving the versatility and adaptability of the device, thereby solving the problem that the monitoring device in the prior art cannot monitor the water distribution and dynamic changes of water in the fuel cell manifold online.

[0027] Optionally, the insulating probe rod 10 is a telescopic rod.

[0028] Optionally, the insulating probe rod 10 includes a rod body and a guide rail seat, the rod body is slidably connected to the guide rail seat along the extension direction of the guide rail seat, and the camera component 11 is arranged on the rod body.

[0029] In this way, the retractable or slidable characteristics of the insulating probe rod 10 increase its flexibility and operability during the monitoring process. In addition, during use, direct intervention in the structure of the battery stack 100 can be reduced, avoiding structural damage or sealing damage that may be caused by rigidly fixing the probe rod. In this way, monitoring can be performed without changing the existing structure of the battery stack 100, thereby improving the compatibility and practicality of the equipment. By driving the camera component 11 to obtain real-time images at different positions during the telescopic or sliding process, the distribution state of water and gas in the manifold and its dynamic changes can be more accurately analyzed. This multi-angle, multi-position monitoring method can provide more comprehensive data, which helps to more deeply understand the operating conditions inside the battery stack 100, and is of great significance for diagnosing flooding faults, membrane dry faults, etc.

[0030] Specifically, the fuel cell monitoring device further includes a driving component, and one end of the insulating probe rod 10 away from the camera component 11 is connected to the output shaft of the driving component to drive the insulating probe rod 10 to rotate. In this embodiment, the driving component is a servo motor, so that the insulating probe rod 10 drives the camera component 11 to cover different angles at different positions in the manifold, and the real-time distribution state of water and gas in the manifold is monitored in real time, which is helpful for timely response and prevention of failures.

[0031] In this embodiment, the insulating probe rod 10 is a straight rod. Thus, compared with a probe rod with a curved or complex shape, the structure is simpler, which helps to reduce manufacturing costs and improve the reliability of the device. A simple structure usually means fewer parts and connection points, thereby reducing potential failure points of the insulating probe rod 10. In addition, the straight rod structure has a more uniform distribution of inertial force during rotation, so the rotational stability is better, which helps the camera component 11 to be more stable when acquiring images and reduce image jitter caused by rotation.

[0032] Specifically, the mirror surface of the camera component 11 is located on the outer peripheral surface of the insulating probe rod 10. In this way, when the insulating probe rod 10 rotates in the manifold, it can achieve 360-degree all-round monitoring of the internal environment of the manifold, ensuring that there are no blind spots in all monitored areas, thereby improving the comprehensiveness and accuracy of monitoring. Even in the complex structure of the battery stack 100, the effective monitoring range of the camera component 11 can be guaranteed to meet different monitoring needs.

[0033] Please refer to Figure 3 As shown, another aspect of the technical solution of the present invention provides a fuel cell monitoring method, which is applicable to the fuel cell monitoring device mentioned above. The fuel cell monitoring method includes: when the battery stack 100 is operating normally, controlling each insulating probe rod 10 to move in the manifold of the battery stack 100, and controlling each insulating probe rod 10 to rotate; analyzing the real-time image picture acquired by the camera component 11 on each insulating probe rod 10, so as to obtain the real-time dynamic distribution change of water and the dynamic change of gas-liquid two phases in the manifold of the battery stack 100. In this way, by controlling the movement and rotation of the insulating probe rod 10 in the manifold, the camera component 11 can acquire real-time images from different angles and positions. The real-time images can timely identify the real-time dynamic distribution information of water and the real-time dynamic information of gas-liquid two phases through data processing, which is helpful to quickly judge the occurrence of water management faults at various locations in the battery stack 100, such as flooding and membrane dry faults, so as to take measures in advance to avoid or alleviate the faults, extend the life of the fuel cell and improve its working efficiency.

[0034] By adopting the above-mentioned device, it is possible to monitor the water vapor distribution inside the fuel cell in real time, effectively prevent performance degradation and failure caused by improper water management, and is suitable for various types of fuel cell stacks 100, especially in high-power and complex structure battery stacks 100, and can provide more detailed monitoring data. Implementation effect and application scenarios: The implementation effect of the monitoring device is significant, and can greatly improve the operating efficiency and reliability of the fuel cell system. In high-power fuel cell stacks 100, such as automobiles, ships and large fixed power sources, it can promptly detect and locate problems such as moisture accumulation and bubble blockage, avoid performance degradation and potential failures, and ensure stable operation of the system. Especially in applications in extreme environments, such as extremely cold or hot conditions, the flexibility and accuracy of the device are particularly important, which helps the system maintain optimal performance under harsh conditions.

[0035] Furthermore, the step of analyzing the real-time image acquired by the camera components 11 on each insulating probe rod 10 includes: controlling each camera component 11 to transmit the real-time image acquired at different vertical positions and different horizontal positions to the signal distributor 200, the signal distributor 200 sends the real-time image to the mobile terminal 300 through a signal, and the mobile terminal 300 processes the image data of the real-time image to obtain the real-time dynamic distribution information of water in the manifold and the real-time dynamic information of the gas-liquid two-phase. In this way, the acquisition and transmission of the real-time image enables the monitoring system to monitor the water distribution and gas-liquid two-phase dynamics inside the fuel cell manifold online, which is more timely than the traditional offline analysis, can quickly respond to the changes inside the battery stack 100, and help to diagnose water management problems such as flooding and membrane dry failure in real time. In addition, by processing the image data through the mobile terminal 300, advanced image recognition and analysis algorithms can be used to improve the accuracy and precision of the analysis of water distribution and gas-liquid two-phase flow state. The processed data can more intuitively reflect the complex situation inside the battery stack 100, help to accurately identify the fault location and status, thereby effectively extending the service life of the battery stack 100 and ensuring the stability and efficiency of the fuel cell system.

[0036] In this embodiment, the monitoring method also includes: identifying the real-time dynamic distribution information of water in the manifold and the real-time dynamic information of the gas-liquid two-phase, and judging the occurrence of water management faults in various places in the battery stack 100. In this way, the distribution status of water and gas inside the battery stack 100 can be fed back immediately, which helps to predict possible water management faults in advance, take timely measures to prevent further development of faults or quickly solve the faults that have occurred, thereby improving the stability and durability of the fuel cell system. So that based on the real-time monitored water and gas distribution information, the water management strategy can be optimized, such as adjusting parameters such as humidity, temperature, and pressure, to ensure that the fuel cell operates under optimal working conditions and improve its efficiency and performance.

[0037] According to another aspect of the technical solution applied to the present invention, a non-volatile storage medium is provided, wherein the non-volatile storage medium includes a stored program, wherein when the program is running, the device where the non-volatile storage medium is located is controlled to execute the above-mentioned fuel cell monitoring method.

[0038] In another aspect of the technical solution applied to the present invention, a computer device is provided, including: a memory and a processor, the memory storing a computer program; the processor is used to execute the computer program stored in the memory, and when the computer program is running, the processor executes the fuel cell monitoring method mentioned above.

[0039] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0040] The fuel cell monitoring device includes a plurality of insulating probe rods 10 and a plurality of camera components 11. At least a portion of each insulating probe rod 10 extends into the manifold of the battery stack 100 and is movably arranged. Each insulating probe rod 10 is rotatably arranged around its axis. The plurality of camera components 11 are respectively and correspondingly arranged on the outer peripheral walls of the plurality of insulating probe rods 10, so that when the insulating probe rods 10 move in the manifold, they drive the camera components 11 to obtain the distribution status of water and gas in the manifold.
