[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Electrolysis of water is a relatively mature method for producing hydrogen. Direct current is passed through an electrolyzer filled with electrolyte, causing water molecules to undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. Hydrogen, as a clean energy source, can be used in fuel cell power generation, providing a stable and reliable power supply to the grid. It can also be used as fuel for fuel cell vehicles, offering advantages such as zero emissions and high energy efficiency. Hydrogen is also an important raw material for many chemical reactions, such as the synthesis of ammonia and methanol. As a clean and sustainable energy production method, water electrolysis for hydrogen production has broad application prospects and significant strategic importance. In the future, with continuous technological advancements and cost reductions, water electrolysis for hydrogen production is expected to become one of the mainstream hydrogen production methods.

[0021] Hydrogen purification refers to the process of removing impurities from hydrogen gas using physical or chemical methods. Impurities in hydrogen gas can pose safety hazards, such as explosions. Purification helps eliminate these hazards and ensures the safe use of hydrogen. With the development of the semiconductor, fine chemical, and optoelectronic industries, the demand for high-purity hydrogen is increasing. Purification can meet the specific requirements of these industries for high-purity hydrogen. Hydrogen in nature always exists in the form of compounds such as water and hydrocarbons, and impurities are unavoidable during hydrogen production. Purification can significantly improve the purity of hydrogen gas.

[0022] The hydrogen purification system is a key component of an alkaline water electrolysis hydrogen production system. Its main function is to remove impurities such as oxygen, water, mechanical impurities, and dust particles from the hydrogen produced from the electrolyzer. A hydrogen purification system typically consists of a deoxygenator, dryer, cooler, gas-liquid separator, gas filter, valves, pipelines, and various control devices.

[0023] The hydrogen purification system controller is a key component of the hydrogen purification system, responsible for monitoring and controlling the entire purification process. Therefore, this application proposes a hydrogen purification system controller, comprising: a housing 100, a housing cover 200, and a control circuit board 300.

[0024] refer to Figure 1 , Figure 2 and Figure 3 . Figure 1 This is a schematic diagram of the overall structure of the hydrogen purification system controller. Figure 2 This is a schematic diagram of the connection structure of the EMC circuit and the rectifier voltage regulation circuit of the hydrogen purification system controller. Figure 3 This is a schematic diagram of the connection structure between the power module and the control module of the hydrogen purification system controller.

[0025] The housing 100 has multiple positioning posts 110 inside, which are used to fix the embedded control circuit board 300. A first opening is provided on the left side of the housing 100. A heat dissipation vent is provided on the top of the cover 200, and a second opening is provided on the left side of the cover 200. The first and second openings form a first gap, which is used to house the first interface area of ​​the control circuit board 300. In this embodiment, an RJ45 interface is provided in the first interface area. RJ45 is a network interface connector, belonging to the twisted-pair Ethernet interface type. RJ45 plugs are commonly used for computer network data transmission and are found in network cards, hubs, switches, telephones, and other devices. RJ45 plugs can only be inserted in a fixed direction and have eight grooves and a locking mechanism to prevent misinsertion.

[0026] In order to house the second interface area of ​​the control circuit board 300, in some further specific embodiments, a third opening is provided on the front of the housing 100 and a fourth opening is provided on the front of the cover 200. The third opening and the fourth opening form a second gap, which is used to house the second interface area of ​​the control circuit board 300.

[0027] To house the third interface area of ​​the control circuit board 300, in some further specific embodiments, a fifth opening is provided on the right side of the housing 100, and a sixth opening is provided on the right side of the cover 200. The fifth and sixth openings form a third gap, which is used to house the third interface area of ​​the control circuit board 300. The second and third interface areas are equipped with various interfaces, such as various sensor interfaces, device interfaces, and communication interfaces.

[0028] In order to fix the box body and the box lid, in some further specific examples, multiple bolt through holes are provided around the box body 100 and multiple bolt through holes are provided around the box lid 200. The bolt through holes around the box body 100 correspond one-to-one with the bolt through holes around the box lid 200, and the box lid is fixed to the box body with bolts.

[0029] In order to secure the hydrogen purification system controller, in some further specific examples, multiple bolt holes are provided at the bottom of the housing 100 for securing the controller. The controller can be secured simply by screwing the bolts into the bolt holes.

[0030] To convert alternating current (AC) to the required direct current (DC), in some further specific examples, the control circuit board 300 includes a power module. The power module includes an EMC (Electromagnetic Compatibility) circuit and a rectifier / voltage regulator circuit, with the EMC circuit connected to the rectifier / voltage regulator circuit. The rectifier / voltage regulator circuit converts AC to 12V, 5V, and 3.3V DC for use by various functional modules and devices, while the EMC circuit prevents electromagnetic interference, making the equipment operate more stably.

[0031] EMC refers to the ability of a device or system to function normally in its electromagnetic environment without causing unacceptable electromagnetic interference to anything in that environment. This is a comprehensive performance characteristic of electronic equipment or systems in terms of electromagnetic fields, encompassing two requirements: 1. The electromagnetic energy generated by the device or system during normal operation must not exceed a certain limit; that is, the device or system should not generate electromagnetic interference exceeding the specified limit. This is primarily to prevent the device or system from interfering with other electronic equipment in its surrounding environment and affecting their normal operation. 2. The device or system must have a certain degree of immunity to electromagnetic interference present in its environment; that is, the device or system should still function normally under certain electromagnetic interference without performance degradation or failure. This is to ensure that the device or system has sufficient stability and reliability in its electromagnetic environment.

[0032] To control the hydrogen purification system, in some further specific examples, the control circuit board 300 also includes a control module, which comprises an MCU (Microcontroller Unit) circuit, a relay drive circuit, a MOSFET drive circuit, a sampling circuit, and a communication circuit. An MCU is a small computer system that integrates multiple functions such as a CPU (Central Processing Unit), memory, I / O interfaces, an analog-to-digital converter (A / D converter), and a timer / counter, and is often used in dedicated control systems. A MOSFET is a metal-oxide-semiconductor field-effect transistor.

[0033] The system uses relay-driven circuits to control connected devices such as solenoid valves, heating elements, and fans. Sampling circuits connect to various sensors to collect information such as hydrogen concentration, gas pressure, and temperature within the purification system. Communication circuits connect to Bluetooth, RS-485, Ethernet modules, and various sensors, allowing for flexible selection of multiple communication methods. RS-485 is a differential transmission, balanced reception serial communication standard with common-mode interference suppression capabilities, enabling long-distance, high-speed data transmission. Bluetooth is a wireless technology standard designed for short-range data exchange between fixed devices, mobile devices, and building LANs.

[0034] This embodiment also provides a hydrogen purification system, including a hydrogen purification system and any of the above-mentioned hydrogen purification system controllers.
