Application of vehicle hydrogen sensor in hydrogen fuel cell storage cabinet

        The vehicle hydrogen sensor has the following applications in the hydrogen fuel cell storage cabinet:

        1. Hydrogen leak monitoring:

        ● Real-time detection: A large amount of hydrogen is stored in the hydrogen fuel cell energy storage cabinet, and because the hydrogen molecule is very small, it is easy to leak from the tiny gap in the storage container or pipeline. The on-board hydrogen sensor can monitor the hydrogen concentration in the energy storage cabinet and the surrounding environment in real time, and once the hydrogen concentration exceeds the safety threshold, the sensor will immediately issue an alarm to remind the staff to deal with it in time. For example, in daily operation, if the sealing parts of the energy storage cabinet are aging or damaged, resulting in hydrogen leakage, the sensor can quickly detect and issue an early warning to avoid safety accidents caused by hydrogen leakage.

        ● Location of the leak point: By placing multiple hydrogen sensors in different locations of the energy storage cabinet, the approximate location of the hydrogen leak can be initially determined according to the alarm information of the sensor, helping the staff to quickly locate the leak point for timely maintenance and treatment, and reducing the risk and loss of hydrogen leakage.

        2. Hydrogen purity test:

        The purity of hydrogen has an important effect on the performance and efficiency of hydrogen fuel cells. The on-board hydrogen sensor can detect the purity of hydrogen entering the energy storage tank and the hydrogen output from the energy storage tank to the fuel cell to ensure that the purity of hydrogen meets the working requirements of the fuel cell. If the hydrogen is mixed with other impurity gases, such as oxygen, nitrogen, carbon monoxide, etc., the sensor will detect the change in purity and send a corresponding signal, so that measures can be taken to purify or replace the hydrogen to ensure the normal operation of the fuel cell and efficient power generation.

        3. System condition monitoring and fault diagnosis:

        ● Monitoring the state of the energy storage system: the sensor can monitor the working state of the hydrogen fuel cell energy storage cabinet, such as hydrogen pressure, temperature and other parameters. Through real-time monitoring of these parameters, we can understand the operation of the energy storage system and determine whether the system is in normal working state. For example, when the hydrogen pressure is too high or too low, it may affect the performance and safety of the fuel cell, and the sensor will feedback the status parameters in time for the staff to adjust and maintain.

        ● Auxiliary fault diagnosis: If the energy storage cabinet fails, the on-board hydrogen sensor can provide relevant fault information to help the staff diagnose the fault. For example, when the sensor detects an abnormal change in the concentration of hydrogen, but there are no obvious signs of leakage, it may be that some parts in the energy storage cabinet have failed, affecting the normal storage and delivery of hydrogen. At this time, the staff can carry out further inspection and maintenance according to the sensor information, improving the efficiency and accuracy of fault diagnosis.

        4. Safety warning and emergency treatment:

        ● Safety warning: During the operation of the hydrogen fuel cell storage cabinet, the on-board hydrogen sensor can be linked with other safety equipment and systems to form a complete safety warning system. When the sensor detects hydrogen leakage or other abnormal conditions, it will immediately trigger the safety warning device, such as sound and light alarm, automatic cutting device, etc., to remind the staff to take emergency measures in time to ensure the safety of personnel and equipment.

        ● Emergency treatment support: In the event of an emergency, the real-time monitoring data of the sensor can provide an important reference for emergency treatment. For example, in dangerous situations such as fire or explosion, sensors can help workers understand the leakage and concentration distribution of hydrogen in order to develop reasonable emergency treatment plans, such as choosing appropriate fire suppression methods and evacuating personnel.
