Jichong Hydrogen Energy completed the development of integrated single-cell technology, driving the improvement of mass production capability for metal plate stacks.

Jichong Hydrogen recently made new progress in the manufacturing process of fuel cell metal plate stacks. The company's independently developed single-cell integrated manufacturing process has been successfully completed, providing new process support for the advancement of large-power fuel cell stacks towards high performance, high reliability, and low-cost mass production.

The fuel cell stack is a core component of the hydrogen fuel cell system. Its manufacturing precision, sealing reliability, and single cell consistency directly affect the operational efficiency and service life of vehicles or equipment. At present, most metal plate stacks in China still adopt the traditional structure route of "bipolar plate + membrane electrode assembly," which often leads to problems such as bipolar plate warpage, insufficient stack stacking accuracy, and low assembly efficiency during production.

These process difficulties not only affect the sealing performance of the stack but may also lead to a decrease in single cell consistency, thereby increasing subsequent testing, maintenance, and manufacturing costs. For the fuel cell industry that is moving towards large-scale application, how to improve stack manufacturing efficiency and reduce batch production costs has become a key aspect of enterprise competition.

Focusing on industry pain points, Jichong Hydrogen, leveraging years of accumulation in the research and development and mass production of large-power metal bipolar plate stacks, has independently developed the single-cell integrated manufacturing process for metal plate stacks. This process restructures the stack assembly method from the manufacturing source, helping to reduce structural defects in traditional assembly processes and improve the stability of subsequent stacking and mass production.

According to reports, the relevant process has currently completed reliability verification such as high-low temperature cycles, damp heat cycles, high-low voltage tolerance, and special medium immersion , demonstrating that it has a basis for further industrial application under complex operating conditions. The development of the new process is expected to enhance the reliability and consistency of stack products and reduce production and later operation and maintenance costs.

From the perspective of industrialisation, the significance of the integrated single-cell process lies not only in a single technological breakthrough but also in providing a more efficient manufacturing pathway for the large-scale production of large-power fuel cell stacks. As application scenarios such as hydrogen heavy-duty trucks, construction machinery, ships, and stationary power generation accelerate expansion, the demand for high-power, high-durability, and low-cost stacks will continue to grow.

The completion of this process development by Jichong Hydrogen will further solidify its manufacturing capabilities in the field of fuel cell metal plate stacks. In the future, as the process undergoes continuous verification and optimisation in mass production stages, the enterprise is expected to form stronger support for the localisation of core fuel cell components, cost reduction and efficiency improvement, and market promotion.
