[0002] To promote the healthy, orderly and sustainable development of the hydrogen energy industry and achieve "low-carbon" emissions in the hydrogen production process, seawater is used as a raw material for hydrogen production. However, existing offshore electrolytic water hydrogen production equipment has many problems such as low hydrogen production efficiency, high energy consumption, and high cost, and problems such as renewable energy consumption and high hydrogen production cost need to be solved;

[0003] The present invention designs a renewable energy electrolytic water hydrogen production buoy platform based on an efficient catalyst, aiming to achieve the "greening" of hydrogen production and the utilization, storage and transportation of offshore clean energy. Summary of the Invention

[0004] The purpose of the present invention is to propose a renewable energy electrolytic water hydrogen production buoy platform based on an efficient catalyst in order to solve the problems in the above background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A renewable energy electrolytic water hydrogen production buoy platform based on an efficient catalyst includes an electrolyte supply module, an electrolytic water hydrogen production module, a multi-source coupled power generation module and an energy storage module. The electrolyte supply module is composed of an electrolyte evaporation chamber and an electrolyte storage chamber. The electrolytic water hydrogen production module is located above the electrolyte supply module. The multi-source coupled power generation module is arranged on the upper side of the electrolyte supply module. The energy storage module consists of a hydrogen storage tank and a storage battery.

[0007] As a further description of the above technical solution:

[0008] The part of the electrolyte supply module in contact with seawater is provided with an impurity filter screen. The electrolyte supply module includes an electrolyte storage chamber arranged under the electrolytic water hydrogen production module. An electrolyte evaporation chamber is arranged inside the electrolyte storage chamber. A PTFE membrane filter screen and an electric heating tube are arranged inside the electrolyte evaporation chamber. The impurity filter screen is arranged at the bottom part inside the electrolyte evaporation chamber. The PTFE membrane filter screen, the electric heating tube and the impurity filter screen are arranged in sequence from top to bottom inside the electrolyte evaporation chamber.

[0009] As a further description of the above technical solution:

[0010] The electrolytic water hydrogen production module includes an electrolytic reaction tank. A magnet is arranged inside the electrolytic reaction tank. The electrolytic water hydrogen production module uses a catalyst and cooperates with a neodymium iron boron strong magnet to generate a magnetic field.

[0011] As a further description of the above technical solution:

[0012] The multi - coupling power generation module is composed of a photovoltaic solar panel and a wind power generation module. Among them, the wind power generation module adopts a combined H - type and S - type vertical - axis wind turbine.

[0013] As a further description of the above technical solution:

[0014] The energy storage module is composed of a hydrogen storage tank and a storage battery. A rotary fixing frame is arranged under the hydrogen storage tank. An active joint sleeve is connected under the rotary fixing frame. The active joint sleeve is connected to the electrolytic water hydrogen production module. The storage battery is electrically connected to the multi - coupling power generation module.

[0015] As a further description of the above technical solution:

[0016] The specific preparation process of the catalyst is as follows:

[0017] Mix 0.12 mmol of FeCl3, 0.06 mmol of iron powder, 0.18 mmol of 4,4'-bipyridine, 50 mL of ethanol, carbon nanotubes (CNTs, 70 mg); melamine (Mel, 0.5 g); CNTs (70 mg) / NaCl (5 g) template in a 100 - mL beaker, and perform magnetic stirring at room temperature for 6 hours. Then filter, rinse with ethanol, and bake overnight in an oven at 60 °C to synthesize CP / CNT, CP / Mel, CP / CNT / NaCl precursors;

[0018] The precursor is calcined in a tubular furnace with an Ar - passing anhydrous and anaerobic atmosphere. The annealed products are denoted as Fe3N - M, Fe3N - C, Fe3N - C N. Through subsequent electrochemical tests, Fe3N - C N is determined as the target catalyst.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, an impurity filter screen is provided at the part of the electrolyte replenishment module in contact with seawater. During operation, seawater enters the evaporation chamber after being filtered by the filter screen, is heated and evaporated by the heating tube, and then liquefied and stored in the electrolyte storage chamber. This module replenishes the pure water consumed by electrolysis with a relatively high desalination efficiency, realizes continuous and stable water migration through the "liquid - gas - liquid" mechanism, can keep the water migration rate equal to the electrolysis rate, realizes continuous and stable electrolysis. The electrolytic water hydrogen production module uses a catalyst and cooperates with a neodymium - iron - boron strong magnet to generate a magnetic field, enabling bubbles to quickly leave the electrode surface, reducing the internal resistance and over - potential, thereby improving the energy conversion efficiency of electrolytic water hydrogen production.

[0021] 2. In the present invention, a low-cost and high-efficiency electrolytic water hydrogen production module is developed. Through the catalyst, the production cost of the catalyst is reduced. At the same time, with the cooperation of the external magnetic field, the hydrogen production reaction activity and the overall electrolysis efficiency are improved, realizing "low cost" and "high efficiency" in the hydrogen production process;

[0022] An electrolyte replenishment module with zero energy consumption and low corrosion is designed. By adopting the seawater desalination technology combining PTFE membrane and electric heating tube, and using solar energy and wind energy to power the electric heating tube, "zero energy consumption" and "high efficiency" in the hydrogen production process are realized, avoiding the problem of catalyst corrosion in direct hydrogen production.

[0023] 3. In the present invention, during the operation stage of the multi-source coupled power generation module, the S-type vertical axis wind turbine provides the starting torque to drive the H-type vertical axis wind turbine to start, and transfers the captured wind energy in the form of wind wheel rotation. The photovoltaic module can generate solar power when there is no wind or little wind. Through this module, all-weather self-powered hydrogen production can be realized, thus realizing "low carbon" and "green" in the hydrogen production process; Hydrogen can be pressurized in a suitable structure up to 70 MPa and stored in a high-pressure hydrogen storage cylinder in the form of gas. The storage battery can store and protect the excess load power generated by the power generation device as reserve electric energy, and provide additional electric energy to the load module when the power generation is insufficient to achieve the stable and continuous operation of the platform.
