[0035] Working principle:

[0036] The vehicle of the present invention is equipped with a solar panel 1 on the top, which is used to capture sunlight and convert it into electrical energy to be supplied to the electrolysis module 3 for water electrolysis. The electrolysis module 3 includes an electrolyte and electrodes. The electrical energy generated by the solar panel 1 is transmitted to the electrolysis module 3 for water electrolysis, thereby producing hydrogen and oxygen. The vehicle is equipped with a DC-DC converter 6 inside, which is used to convert the voltage of the electrical energy generated by the solar panel 1 into a stable voltage suitable for the electrolysis module 3, so that the electrolysis module 3 can operate stably. At the same time, the electrical energy generated by the fuel cell stack can be stored in the energy storage module 7 through the voltage conversion of the DC-DC converter 6. The water-gas storage integrated tank 9 inside the vehicle can be replenished with water through the water inlet. The water is transported to the electrolysis module 3 through a pipeline for electrolysis to generate hydrogen and oxygen. The generated hydrogen and oxygen flow back into the tank through the pipeline and are stored in the cavity above the water surface. As the gas increases, the pressure in the cavity increases, which will push the water out of the gas chamber and return the water to the water storage chamber through the internal return pipeline. The integrated water-gas storage tank 9 supplies hydrogen through pipelines to the hydrogen fuel cell stack within the power generation module 2, which includes multiple fuel cell units. This stack converts hydrogen and oxygen into electricity through an electrochemical reaction, while also producing water vapor. The vehicle's motor drive system 4 drives the motor, transmission system, and steering system 8, which are used to control the rotation of the wheels and the steering of the entire vehicle. It uses the electricity stored in the energy storage module 7 to drive the vehicle forward. The electricity generated by the fuel cell power generation module is stored in the energy storage module 7, which also has an external charging function. The vehicle is equipped with an external charging port. When the ambient light does not meet the conditions for the solar panel 1 to operate and generate electricity, and the energy storage module 7 is low on power, the external charging port can be used to recharge the energy storage module 7.

[0037] The chassis structure of this utility model utilizes a highly integrated framework design to support and carry all other components. The layout of all components is intuitive, efficient, and compact, ensuring stability and durability. The vehicle body structure 5 features a hollowed-out design, with some components made of transparent materials, allowing students to intuitively understand the vehicle's internal structure and the hydrogen supply system's circulation process. The water-gas storage tank 9, electrolysis module 3, and power generation module 3 are connected through gas pipelines to transmit, store, and utilize the generated hydrogen and oxygen, ensuring a controllable and stable gas supply.

[0038] The utility model is intended to provide a clear, visual and intuitive demonstration of the process of water electrolysis for hydrogen production by photovoltaic power generation, hydrogen storage and hydrogen-oxygen reaction to generate electricity, etc., so as to facilitate the study and research of the internal structure and working principle of the hydrogen energy engine system. Other detailed technical means within the system adopt the existing technology, but the overall technical solution as a technical solution that needs to be protected makes up for the shortcomings of the existing technology.

[0039] The above are only preferred embodiments of the present invention and are intended to help understand the method and core concept of this application. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.

[0040] The utility model comprehensively solves the shortcomings of the existing technology that the actual hydrogen fuel cell engine is large in size and heavy in weight, which makes it difficult to facilitate teaching, research and demonstration. Through reasonable structural design of the water electrolysis module, power generation module, solar panel, DC-DC module, gas storage tank, drive motor and steering motor, the operation and travel of the vehicle system are realized, which provides learners with the opportunity to personally experiment and learn about the relevant structure of hydrogen fuel cell vehicles, helps to promote renewable energy technology and clean energy, cultivates awareness of environmental protection and sustainable development, and provides students with a practical scientific education experience.
