Hydrogen Purification Skid Equipment: The "Purification Heart" for High-Quality Hydrogen Use
Between hydrogen production and application, the purity of hydrogen directly affects the performance and service life of downstream equipment. Regardless of whether the raw hydrogen comes from alkaline electrolysis, PEM electrolysis, or industrial by-product hydrogen, it contains impurities such as water vapor, oxygen, nitrogen, trace alkali mist, or organic substances. Our introduced hydrogen purification skid equipment, with its modular and integrated skid design, provides customers with "plug-and-play" efficient purification capabilities, ensuring that the output hydrogen meets the high requirements of applications such as fuel cells and electronic industry.
1. Equipment Positioning and Core Value
Connecting Hydrogen Production and Utilization: Purifies crude hydrogen from electrolyzers or pressure swing adsorption (PSA) to over 99.997% (meeting the GB/T 37244-2018 standard for fuel cell-grade hydrogen).
Integrated Skid-Mounted Delivery: All purification units, control valves, sensors, and piping are integrated on a steel base. On-site only requires connecting hydrogen inlet and outlet, power supply, and cooling water source, significantly shortening installation and commissioning time.
Inherent Safety Design: Fully implements hydrogen safety concepts from material selection, sealing to control strategies, tailored for hydrogen characteristics.

3. Our Technical Advantages
Full Hydrogen-Grade Fluid Control Capability: All valves, regulators, fittings, and piping inside the equipment use our self-developed hydrogen fluid control products, eliminating leakage or hydrogen embrittlement risks caused by general-purpose components.
Wide Operational Condition Adaptability:
Processing capacity: 10~2000 Nm³/h (customizable)
Inlet pressure: 0.8~3.0 MPa
Adapts to fluctuating gas supply from electrolyzers (30%~110% load)
Low Energy Consumption and Zero Hydrogen Loss: No product hydrogen is consumed during drying regeneration. Compared to traditional PSA processes, the yield increases by 5%~8%.
Modular Expansion: Additional modules such as CO removal and sulfur compound adsorption can be added according to requirements, meeting ultra-pure hydrogen needs for semiconductor and metal heat treatment industries.
4. Typical Application Scenarios
Post-Treatment for PEM/Alkaline Electrolyzers: Purifies electrolyzer hydrogen from 99.5% to over 99.997%, directly supplying hydrogen stations or fuel cell testing platforms.
Purification and Utilization of Industrial By-product Hydrogen: Processes coke oven gas, chlor-alkali by-product hydrogen, etc., removing impurities for use in hydrogen transportation or distributed power generation.
On-site Hydrogen Production for Electronics/Semiconductor Industry: Provides ultra-high purity hydrogen with ppb-level impurity content for chip manufacturing and epitaxial processes.
Laboratory and Pilot Platforms: Compact skid-mounted design facilitates mobility and rapid deployment, meeting the flexible hydrogen needs of scientific research.
5. Value Created for Customers
