[0002] Existing fuel cell power generation systems typically employ a highly integrated and enclosed enclosure design. While this design is beneficial for protecting internal components, it has significant drawbacks for scenarios such as teaching demonstrations, scientific research testing, and exhibitions: users cannot intuitively see the internal components and piping layout, resulting in a high learning and research threshold and failing to meet the needs for visualization and intuitiveness.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-5 A visualization fuel cell system includes a transparent viewing enclosure, which includes an enclosure frame 1. The enclosure frame 1 has multiple visualization windows, and each visualization window is equipped with a transparent protective plate. The transparent viewing enclosure is arranged with fuel cell components according to functional zones. By setting multiple visualization windows, real-time visualization observation of the fuel cell components can be realized, which is convenient for intuitive understanding of the component operation status, pipeline connection status and potential anomalies during scientific research and testing.

[0020] Multiple visualization windows are distributed on the top, front, back, front, and rear of the chassis frame 1. The transparent protective panels are positioned according to the visualization window locations as follows: a transparent top panel 101 is located at the top visualization window; two transparent side panels 102 are located at the front and rear visualization windows respectively; a transparent front panel 104 is located at the front visualization window; and a transparent rear panel 105 is located at the rear visualization window. The transparent protective panels are made of acrylic, high-strength tempered glass, or flame-retardant PC transparent panels. They are connected to the chassis frame 1 by bolts or snap-fit ​​connections. The multi-faceted visualization window distribution design allows for comprehensive observation of the system's internal structure, enhancing the overall scope of observation.

[0021] The fuel cell assembly includes an intake solenoid valve 9, a dust filter 11, a pressure sensor, a fuel cell stack 12, and an exhaust solenoid valve 10 connected in sequence. All components are bolted to the housing frame 1, and are connected via pipelines. The intake solenoid valve 9, dust filter 11, pressure sensor, fuel cell stack 12, and exhaust solenoid valve 10 are integrated at the intake end and at the exhaust end, ensuring the safety and lifespan of the fuel cell stack 12. The dust filter 11 at the intake end effectively prevents impurities from entering and damaging the fuel cell stack 12. During system operation, power is applied for monitoring before any issues are confirmed, thus avoiding safety hazards caused by blindly introducing air.

[0022] The exhaust solenoid valve 10 is connected to an exhaust port 6 via a pipeline, and the exhaust port 6 is located on the transparent protective plate, specifically on the transparent front panel 104.

[0023] The intake solenoid valve 9 is connected to the hydrogen inlet 5 via a pipeline, and the hydrogen inlet 5 is located on the transparent front panel 104. The hydrogen inlet 5 is used to connect to the hydrogen source. The hydrogen source enters the anode of the fuel cell stack 12 through the hydrogen inlet 5, the intake solenoid valve 9, the dust filter 11, and the pressure sensor. The reaction exhaust gas is discharged from the exhaust port 6 through the exhaust solenoid valve 10.

[0024] A transparent partition 106 is bolted to the inside of the chassis frame 1. A controller 13 is bolted to the transparent partition 106. The fuel cell stack 12 is equipped with a fan 14, which is communicatively connected to the controller 13. The fan 14 is controlled by the controller 13 via a PWM signal to provide the fuel cell stack 12 with the air required for the reaction and to perform air cooling. An air exchange port 103 is provided on the transparent side panel 102. The controller 13 is an FDC controller, FCU controller, or PLC controller. The transparent partition 106 not only separates the internal space of the chassis frame 1 but also does not affect observation. The fan is controlled by the controller's PWM signal and can precisely adjust its speed according to the temperature and reaction requirements of the fuel cell stack 12. This ensures that the fuel cell stack 12 is provided with sufficient reaction air and can achieve air cooling on demand, avoiding excessively high or low stack temperatures that could affect power generation efficiency and service life. The air exchange port 103 allows for air circulation inside and outside the chassis frame 1, improving the air cooling effect.

[0025] The controller 13 is electrically connected to a DC-DC module, and the DC-DC module is electrically connected to an HMI4. The HMI4 is mounted on a transparent protective plate, specifically on the transparent front panel 104. The HMI4 is used to display system operating parameters in real time and serves as a human-machine interface screen. The DC-DC module enables precise voltage conversion within the system, ensuring that the output voltage of the controller 13 matches the voltage required by the HMI4, thus guaranteeing the stable operation of the HMI4. The HMI4 is mounted on the transparent front panel 104, making it convenient for operators to view system operating parameters in real time.

[0026] The controller 13 is connected to a lithium battery 8, which is bolted into the chassis frame 1; the lithium battery 8 provides power to the controller 13, HMI4 and other components.

[0027] The lithium battery 8 is equipped with a charging port 15, which is mounted on a transparent protective plate, specifically on the transparent front panel 104, to facilitate the operator to charge the lithium battery 8.

[0028] The controller 13 is connected to the inverter 7, which is bolted to the transparent partition 106. The inverter 7 is used to connect the load, and the chassis frame 1 has an operation port exposed on the inverter 7 panel. The inverter 7 is a DC-AC inverter. The DC-AC inverter can convert the DC power generated by the fuel cell stack 12 into AC power, which can meet the usage requirements of most AC loads and expand the application range of the system.

[0029] It also includes a lithium battery switch 2 installed on the transparent front panel 104, which is used to control the power on and off of the HMI4 and the controller 13. A system switch 3 is also installed on the transparent front panel 104, which is used to control the start and stop of the intake solenoid valve 9 and the exhaust solenoid valve 10. Control Logic: The system adopts a two-step startup logic. First, after pressing the lithium battery switch 2, the HMI4 and controller 13 are powered on. The HMI4 reads and displays the data collected by the controller 13 in real time, including the voltage and SOC of the lithium battery 8, the voltage, current, and temperature of the fuel cell stack 12, the voltage and current of the load, and the hydrogen inlet pressure. Second, after pressing the system switch 3, the intake solenoid valve 9 opens, and hydrogen enters the fuel cell stack 12 to generate electricity, thereby powering the HMI4. The deep integration of the HMI4 and controller 13 allows users to grasp the core data of the system operation in real time and accurately, which is convenient for scientific research testing and status assessment.

[0030] Power output: The DC power generated by the fuel cell stack 12 is output to the inverter 7 via the controller 13, and finally converted into AC power to supply the external load. The system also includes a DC-DC module for internal voltage conversion.
