Recently, Guangzhou Shuntian Equipment Manufacturing Co., Ltd. successfully delivered a PEM water electrolysis hydrogen production line project, a collaboration with a certain company. This production line will provide efficient and stable support for the customer's green hydrogen production, contributing to the development of my country's hydrogen energy industry.
As a national high-tech enterprise and a specialized and innovative enterprise in the field of hydrogen energy equipment, Shuntian Equipment has extensive experience in PEM water electrolysis hydrogen production technology. The delivered production line integrates multiple core technologies to achieve fully automated production, effectively improving production efficiency and product quality.
The production line utilizes an advanced six-axis robot for gripping and stacking bipolar plates and membrane electrodes, coupled with a high-precision vision alignment system to ensure minimal component alignment errors. The automatic bolt locking machine utilizes servo control technology to avoid uneven force caused by manual tightening, ensuring electrolyzer performance and stability.
In terms of assembly precision, the electrolyzers produced on this production line achieve industry-leading flatness throughout the entire cell. Advanced differential pressure testing demonstrates a leak rate far below the industry average. Feedback from a 100MW green hydrogen project shows that after 10,000 hours of electrolyzer operation, the membrane electrode degradation rate was only 5%, lower than the industry average of 10%, reducing equipment maintenance costs.
This production line features robust data traceability and capacity adaptability. Operating parameters are uploaded to the MES system in real time, enabling five years of data storage and one-click backup, facilitating quality monitoring and traceability. Furthermore, a single shift can accommodate multiple 1.2MW electrolyzers, allowing rapid capacity expansion based on customer demand to meet the needs of projects of varying sizes.

Renewable energy hydrogen production is the only green, low-carbon hydrogen production method that not only improves grid flexibility but also enables long-distance transportation and distribution of renewable energy, supporting the larger-scale development of renewable energy. As a medium, hydrogen promotes the spatial and temporal redistribution of renewable energy, helping the power system establish industrial connections with industries such as industry, construction, and transportation that face challenges in deep decarbonization, and continuously expanding hydrogen's application scenarios. This also creates significant development potential for PEM water electrolysis hydrogen production technology.
This client is a wholly state-owned power generation enterprise established during the national power system reform and a key state-owned backbone enterprise directly under the central government. Its primary businesses include electricity and heat production and supply, as well as the development of primary energy sources such as coal and related professional technical services. It has industrial sectors including electricity, heat, coal, science and technology engineering, and industrial finance, with assets and businesses located in 32 provinces (autonomous regions, and municipalities) across China, as well as in countries along the Belt and Road Initiative, such as Russia, Indonesia, Cambodia, and Vietnam.
It has 50 directly affiliated units, 409 grassroots enterprises, and holdings in six listed companies. It currently employs 98,000 people and has total assets of one trillion yuan. It maintains national-level technical centers for thermal power generation efficiency testing, distributed energy technology, gas turbine monitoring, diagnosis, and operation and maintenance services, as well as multiple technological innovation platforms focused on power network security for thermal power and renewable energy. They are actively cultivating their hydrogen energy technology advantages and have collaborated with our company to build a fully automated PEM electrolyzer production line, successfully rolling off the production line for 500 standard cubic meters of electrolyzers.
Part 01 Electrolyzer Assembly Line - Scope of Application
This production line is primarily used for the complete assembly and testing of various PEM electrolysis stacks. It can complete all PEM electrolysis stack processes and produce a full range of stack sizes. It enables stacking, assembly, and online airtightness testing of electrolyzer stacks. Robotic stacking replaces manual labor, offering high accuracy and preventing uncontrollable factors such as missed or incorrect stacks during manual assembly.
Two control modes: pressure mode as the primary mode and position mode as the auxiliary mode, work together to ensure product safety. While robotic stacking is in progress, manual bolt locking, airtightness testing, and finished product unloading can also be performed, improving production efficiency. The servo-hydraulic closed-loop control system precisely stores system pressure history data for traceable parameters.
Part 02 Electrolyzer Assembly Line - Advantages and Features
This production line is an automated stack assembly line with a modular design. It includes raw material storage, bipolar plate cleaning, visual inspection, glue dispensing, sealant application, conveying and stacking of end plates, bipolar plates, and membrane electrode systems, and flexible assembly. It features hydraulic servo stacking, automatic screw threading and locking, automatic tooling positioning, airtightness testing, laser marking, and screw locking. High-rigidity carriers limit servo stacking, automatic bolt tightening, stack airtightness testing, laser marking, and finished product unloading. It is compatible with the production of PEM electrolysis hydrogen stacks of various sizes. The entire production process is monitored by an MES system, providing full data traceability, allowing for rapid expansion of production capacity based on production needs. The line features scientific and rigorous processes, information-based production, and high stability.
Through joint efforts with the customer, the production line was quickly delivered. This project is of great significance and assistance to the customer in accelerating the delivery of PEM electrolyzers.
The customer conducted a comprehensive review of the production line's operations and highly praised its efficiency, product quality, and management level. Customer feedback highlights:
1. Excellent stability: The production line operates continuously without interruption, far exceeding the industry average;
2. Strict quality control standards: Product defect rates are consistently under control, and customers particularly appreciate the precise control of key processes and testing links;
3. Rapid responsiveness: The team quickly and efficiently adjusts the production line in response to changes in customer requirements, ensuring on-time order delivery;
4. Intelligent management highlights: The MES system and IoT technology enable full-process data traceability, which customers have called an "industry benchmark."
A customer representative stated, "The production line equipment provided by Shuntian Equipment Company exceeded our expectations. It is one of the most efficient production lines we have ever worked with, demonstrating exceptional professionalism."
This evaluation fully demonstrates our strengths in areas such as lean production, intelligent manufacturing, and customer collaboration. The team will continue to optimize and create greater value for customers.
