[0033] See also Figure 2 The PEM water electrolysis hydrogen production system includes an electrolytic cell, in which an anode, a cathode and an organic film that allows protons to pass but does not allow gases to pass are arranged.

[0034] Among them, the characteristic of PEM water electrolysis technology is that it replaces the diaphragm and electrolyte in the traditional alkaline electrolyzer with an organic film that allows protons to pass but does not allow gases to pass, thereby greatly reducing the size of the electrolyzer. When the PEM electrolyzer is working, water passes through the anode chamber and undergoes an electrochemical reaction at the anode catalytic reaction interface to be decomposed into oxygen, hydrogen ions and electrons. The hydrogen ions generated at the anode are in the form of hydronium ions (H + ·H2 O) through the organic film and react electrochemically with the electrons transported through the external circuit at the cathode reaction interface to generate hydrogen.

[0035] The electrolyzer is the core of the hydrogen production system. Pure water electrolysis hydrogen production technology is a water electrolysis technology that uses a solid polymer electrolyte proton exchange membrane. The electrolyzer water supply adopts the anode water supply method. Under the action of electric current, the anode reaction decomposes to produce oxygen, hydrogen ions and electrons. Under the action of the electric field, the hydrogen ions pass through the proton exchange membrane and recombine with the electrons on the cathode side to produce hydrogen, which is then stored in a high-pressure hydrogen tank and used when needed.

[0036] Furthermore, the wind turbine is a vertical axial flow wind turbine, and the wind turbine includes a fan assembly. The vertical axial flow wind turbine is an electric power device that utilizes natural energy to convert wind energy into mechanical energy, and mechanical energy into electrical energy.

[0037] Furthermore, the weather station is used to monitor air temperature and humidity, air pressure, wind speed, wind direction, light intensity, etc.

[0038] Furthermore, the photovoltaic power generation system includes photovoltaic components; the photovoltaic components are preferably photovoltaic panels, which are semiconductor devices that use the photoelectric effect to convert sunlight into direct current.

[0039] Furthermore, the hydrogen fuel cell power system includes a hydrogen fuel cell. The hydrogen fuel cell power system is a device that converts hydrogen into electricity.

[0040] Furthermore, the lithium iron phosphate energy storage cabinet battery pack can be repeatedly charged and discharged and store electricity, and can be used when needed, thereby saving energy.

[0041] Furthermore, the electric control system includes a remote controller and a one-button start and stop button. The electric control system distributes power and controls the entire set of equipment, and can be remotely controlled and started and stopped with one button.

[0042] Furthermore, the hydrogen fuel cell integrated energy system experimental device box has tempered glass on the front, styling on the left and right, blinds for ventilation on the back, and photovoltaic panels on the top.

[0043] Furthermore, the hydrogen storage tank system is composed of a plurality of hydrogen cylinders connected in series. The hydrogen cylinder has a capacity of 40L.

[0044] Furthermore, the lithium iron phosphate energy storage cabinet battery pack includes an outer shell cabinet and a heat dissipation and heat preservation air conditioner, the outer shell cabinet is arranged on the side of the hydrogen fuel cell integrated energy system experimental device box, and the heat dissipation and heat preservation air conditioner is installed in the outer shell cabinet. The outer shell cabinet can be placed outdoors and is equipped with a heat dissipation and heat preservation air conditioner to ensure the temperature and humidity inside it, thereby improving the service life of components; the lithium iron phosphate energy storage cabinet battery pack can be repeatedly charged and discharged, thereby saving energy.

[0045] See also Figure 3 The hydrogen fuel cell integrated energy system experimental device also includes a fire protection system, a waste heat recovery and heat dissipation system, and a multi-energy complementary energy management system.

[0046] See also Figure 2 The electric control system includes a microgrid control system, and the microgrid control system includes a PLC controller and an energy router.

[0047] When the PEM electrolyzer is working, water passes through the anode chamber and undergoes an electrochemical reaction at the anode catalytic reaction interface to be decomposed into oxygen, hydrogen ions, and electrons. The hydrogen ions produced at the anode are in the form of hydronium ions (H +·H2 O) through the electrolyte diaphragm, and react electrochemically with the electrons transported through the external circuit at the cathode reaction interface to generate hydrogen; then the hydrogen is stored in a high-pressure hydrogen storage tank and converted into electrical energy for the hydrogen fuel cell power system. During the day, the green electricity produced by the wind turbine and photovoltaic power generation system is stored in the energy storage cabinet battery pack, and released when needed, which saves energy.

[0048] The hydrogen fuel cell integrated energy system experimental device provided in the embodiment of the present application can store electricity generated by natural resources such as wind and sunlight, and utilize electricity-hydrogen-electricity conversion to participate in the power auxiliary service market more flexibly on the basis of the electricity market. It can verify the safety and performance effects of the combined systems of PEM water electrolysis hydrogen production, hydrogen fuel cells, safe electricity storage, solar power generation, wind power and waste heat utilization.

[0049] This application will break through the difficulties of multidisciplinary intersection, multi-system integration, and multi-professional coordination in comprehensive energy through research and integration of systems and technologies such as efficient PEM water electrolysis to produce hydrogen, hydrogen fuel cells, safe electricity storage, solar power generation, wind power, and waste heat utilization, and build a regional multi-energy microgrid integration test platform that can realize gas-to-electricity conversion.
