On March 28, 2025, the Fourth China International Hydrogen Energy and Fuel Cell Industry Exhibition (CHEE 2025) successfully concluded at the Beijing National Convention Center. As one of China's most influential international events in the hydrogen energy sector, this year's expo centered on the theme “Embracing Innovation and Sustainability for Shared Success.” It focused on the deep integration of policy, technology, capital, and application scenarios, establishing six major platforms for the hydrogen industry. The event collectively explored new avenues, pathways, and opportunities for the high-quality development of the hydrogen energy sector.
Guangzhou Shuntian Equipment Manufacturing Co., Ltd. engaged in in-depth discussions with global clients and partners, attracting numerous industry experts and collaborators to stop and negotiate. Although the three-day industry event has concluded, Shuntian Equipment's journey in exploring hydrogen energy technology continues unabated!
1.Electric Servo Press for Stack Assembly
This equipment is primarily designed for high-precision pressing of hydrogen fuel cell stacks using metal bipolar plates or graphite bipolar plates. It also enables stack assembly, pressing, and online gas tightness testing for hydrogen electrolysis cells and flow battery stacks.
Features include inclined stacking, center-of-gravity positioning, and orderly stacking. It enables semi-automatic stacking and cell assembly. Manual handling is required for stacking materials such as cell end plates, current collectors, bipolar plates, and membrane electrode assemblies (MEAs). The high-precision servo press ensures accurate stacking pressure. Manual locking bolts are employed, and external leakage and series leakage tests are conducted using differential pressure/flow methods.
【Advantages and Features】
● Primary pressure mode supplemented by position mode, working in tandem to ensure efficient assembly.
● Servo-hydraulic closed-loop control with precise system pressure regulation, historical data storage, and traceable parameters.
● Real-time pressure curve output, programmable pressing process control, and integrated barcode scanner for smart, information-driven production.
● Optional tilt functionality enhances stack assembly precision and operational convenience.
● Compatible with positioning fixtures for streamlined stacking and superior final results. High-precision multi-stage pressure with servo control. Pressure-assisted hot lamination and rapid cold forming can be configured in parallel for swift switching and product transfer.
2. Fuel Cell Stack Assembly Production Line
This production line is dedicated to assembling graphite plate/metal plate stacks—core components of hydrogen fuel cells. Featuring a modular design and flexible assembly capabilities, it operates as an automated stack assembly line. Key functions include servo-driven stack pressing, manual screw locking, gas-tight insulation testing, CVM/housing installation, laser marking, and screw locking. The line offers comprehensive functionality, enabling automated stacking of MEA/bipolar plates/ end plate assemblies, including automatic QR code scanning and stacking, vision-based alignment, servo-driven stacking with high-rigidity carrier constraints, automatic strap bending and laser welding, stack airtightness testing, laser marking, and finished product unloading. It supports production of stacks in multiple sizes. The entire production process is monitored via the MES system, ensuring full data traceability. Capacity can be rapidly expanded as production demands require. The process is scientifically rigorous, information-driven, and highly stable.
【Advantages and Features】
● Multi-station feeding mechanism enables non-stop loading;
● Automated vision-guided alignment with robotic stacking ensures high speed and precision;
● Multi-speed servo stacking with real-time force feedback, combined with high-rigidity carriers, delivers smooth force application and minimal deformation; automated steel tape feeding, bending, welding, and inspection;
● Scientifically rigorous airtight piping design supporting zero-leak and standard-leak testing
3. Servo Press for Gas Tightness Testing of Membrane Electrode Assembly Bipolar Plates
Suitable for gas tightness testing of fuel cell stacks, PEM water electrolysis hydrogen production stacks, and flow battery stacks. Enables gas tightness testing of hydrogen fuel cell bipolar plates, single and multiple membrane electrode assemblies.
【Advantages and Features】
● Feeding System: Retrieves products individually from trays and recovers separators.
● Scanning System: Identifies QR codes and rejects defective/mixed products.
● Testing System: Standard pressure gauge and flowmeter detect product airtightness; single/multiple sheet testing selectable.
● Discharge system stacks qualified products within the tray while separating non-conforming items.
● Information management system transmits and automatically saves process data including QR code information, test pressure, leakage volume, and production capacity. Compatible with MES and CIM system data communication, supporting one-click backup.
