Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy, and specifically to a highly integrated hydrogen storage and hydrogen transmission power generation module and hydrogen production and storage energy equipment. Background Art

[0002] Proton exchange membrane (PEM) water electrolysis for hydrogen production, storage, and transport applications represents a key branch of modern hydrogen energy technology. This system encompasses the entire hydrogen production process from production to end-use, encompassing several key components: a PEM water electrolysis unit, which splits water into hydrogen and oxygen to produce hydrogen fuel; a hydrogen drying unit, which removes water produced during the electrolysis process to ensure hydrogen purity meets the requirements of various applications; a hydrogen storage unit, crucial for ensuring stable long-term hydrogen storage; and a fuel cell power generation unit, which converts stored hydrogen into electricity to power various devices or the grid. This integrated system is not only technologically efficient and clean, but also designed with safety in mind, enabling its widespread application across multiple sectors.

[0003] Traditional PEM water electrolysis hydrogen production, storage, and transportation integrated systems, due to their low level of integration and large size, are difficult to adapt to mobile or space-constrained applications. Furthermore, the relatively high manufacturing and maintenance costs of large, low-integration PEM water electrolysis hydrogen production, storage, and transportation integrated systems are one of the factors hindering the market adoption of these systems.

[0031] Example 1

[0032] like Figure 1As shown, this embodiment provides a highly integrated hydrogen storage, transmission and power generation module, comprising a hydrogen storage system 100, a hydrogen purification system 200, and a power generation system 300. The hydrogen storage system 100 includes a housing 110 and a hydrogen storage device disposed within the housing 110; the hydrogen purification system 200 is disposed on a side outer wall of the housing 110, with its hydrogen outlet connected to the gas circuit of the hydrogen storage device; and the power generation system 300 is disposed on a side outer wall of the housing 110, below the hydrogen purification system 200.

[0033] This embodiment integrates the hydrogen storage system 100, the hydrogen purification system 200 and the power generation system 300 in a modular and highly integrated manner, so that the structure is compact and exquisite and the space occupied is small.

[0034] like Figure 2 As shown, the hydrogen purification system 200 includes a gas-water separator 210, a drying and regeneration device 220, and a pressure sensor 230. The gas-water separator 210 is used to remove moisture from the hydrogen produced by the upstream hydrogen production device to improve the purity of the produced hydrogen. At the same time, at least one stage of the drying and regeneration device 220 is connected to the hydrogen outlet of the gas-water separator 210 to further remove water vapor from the hydrogen. The hydrogen outlet of the drying and regeneration device 220 is connected to the gas path of the downstream hydrogen storage device. The pressure sensor 230 is installed in the gas path between the gas-water separator 210 and the drying and regeneration device 220 to monitor the hydrogen pressure within the hydrogen purification system 200.

[0035] Furthermore, the hydrogen purification system 200 also includes a first test tube 240 and a second test tube 250. The first test tube 240 is located at the hydrogen outlet of the gas-water separator 210 and is used to verify the water removal efficiency of the gas-water separator 210 during the testing phase. The second test tube 250 is located at the hydrogen outlet of the drying and regeneration device 220 and is used to verify the water removal efficiency of the drying and regeneration device 220 during the testing phase. The first and second test tubes 240 and 250 are small drying tubes filled with color-changing silica gel. The degree of color change of the silica gel upon absorption of water allows visual evaluation of the water removal efficiency of the gas-water separator 210 and the drying and regeneration device 220, providing a convenient and intuitive visual evaluation. Furthermore, the first and second test tubes 240 and 250 are for testing purposes only and are not required during production.

[0036] Furthermore, to better control the on / off state of each pipeline in the hydrogen purification system 200, solenoid valves can be installed on each pipeline, including a first hydrogen charging valve 261, a second hydrogen charging valve 262, a drain valve 263, and a steam valve 264. The first hydrogen charging valve 261 is installed before the air inlet of the drying and regeneration device 220, and the second hydrogen charging valve 262 is installed after the hydrogen outlet of the drying and regeneration device 220. The first hydrogen charging valve 261 and the second hydrogen charging valve 262 are opened and closed simultaneously. Specifically, the first hydrogen charging valve 261 is installed upright between the first test tube 240 and the drying and regeneration device 220, and the second hydrogen charging valve 262 is installed in reverse between the drying and regeneration device 220 and the second test tube 250 to prevent hydrogen from flowing back from the hydrogen storage device. The drain valve 263 is arranged at the water outlet of the gas-water separation device 210, and is used to discharge the water separated by the gas-water separation device 210 to the water tank; the steam valve 264 is arranged at the water outlet of the drying and regeneration device 220, and is used to discharge the drainage generated when the drying and regeneration device 220 is heated to the water tank.

[0037] Please review Figure 1 A liquid collecting plate 270 is provided between the hydrogen purification system 200 and the power generation system 300. The side wall of the upper end face of the liquid collecting plate 270 is raised upward, and the liquid collecting plate 270 is installed at a small angle. The lower end of the liquid collecting plate 270 is provided with a small hole, and the small hole extends to the bottom of the power generation system 300 through a water pipe for drainage. The setting and installation method of the liquid collecting plate 270 can collect condensed water or water leakage generated by the hydrogen purification system 200, prevent water droplets from falling on the electronic components of the power generation system 300 below and causing water damage, thereby ensuring electrical safety. In addition, the liquid collecting plate 270 can also play a supporting role. Specifically, please combine Figure 2 The second test tube 250 , the second hydrogen charging valve 262 and the drain valve 263 are installed on the liquid collecting plate 270 , and the bottom of the drying and regeneration device 220 is also set on the liquid collecting plate 270 .

[0038] like Figure 3 and Figure 4 As shown, combined with Figure 1 The power generation system 300 includes a DC / DC converter 310, an inverter 320, and a fuel cell stack power generation device 330, which are fixed to the side outer wall of the housing 110 in sequence from top to bottom via a mounting plate. The fuel cell stack power generation device 330 is positioned at the very bottom of the housing 110. Its fan 331 can blow the waste heat generated by its operation into the bottom of the housing 110. By taking advantage of the fact that hot air has a lower density than cold air and tends to rise more easily, the hot air rises autonomously within the housing 110, maximizing heat uniformity, making more effective use of the waste heat, and improving energy efficiency.

[0039] The working process of power generation of the power generation system 300 is as follows: the fuel cell power generation device 330 obtains hydrogen from the hydrogen storage device to generate electricity, and the generated DC power is first boosted into DC power with a stable pressure by the DC / DC converter 310, and then converted into 220V AC power by the inverter 320 and output to external electrical equipment; the DC power generated by the fuel cell power generation device 330 can also be first boosted into DC power with a stable pressure by the DC / DC converter, and then stepped down into 24V DC power by the DC / DC step-down circuit of the energy management device and output to the electrical device of the hydrogen production and storage energy equipment.
