Description:

In a fuel cell system, the remaining hydrogen at the stack anode needs to be recirculated back to the inlet to improve hydrogen utilization, and the exhaust gas at the stack outlet contains a large amount of liquid water that must be separated before safe discharge or recirculation. Traditional solutions usually use multiple discrete components such as a separate hydrogen circulation pump, water separator and drain valve, which not only occupy a lot of installation space but also have problems such as parasitic power consumption, loud mechanical noise and low reliability.

The LN series hydrogen post-treatment module is an integrated solution developed precisely to solve this problem. This series includes two product lines:

LN-HYLA ejector recirculation assembly: uses the Venturi ejection principle, using the negative pressure generated when high-pressure hydrogen passes through the Venturi tube to re-eject the remaining hydrogen at the stack outlet back to the inlet, realizing hydrogen recirculation. Compared with the hydrogen pump solution, it has the advantages of zero parasitic power, no mechanical noise, high reliability and small volume. The product integrates hydrogen supply, recirculation, water separation and other customer-customized requirements, fully covering all functional requirements of existing fuel cell systems for the hydrogen path. Main features include: electronically controlled hydrogen supply pressure regulation with stable outlet pressure; ejector hydrogen recirculation (zero parasitic power); water-gas separation; pressure detection; multiple safety control mechanisms; high integration (hydrogen supply, recirculation, pressure detection and water separation highly integrated). Inlet pressure 10~13barg, outlet pressure 0~2.0barg, stable flow 2800L/min (H2), ejection ratio equivalent 0.6~3.0, effective ejection range covering 8~100% Pe. Product weight only 3.75kg.

LN-WTM water separator: as an independent water separation module, the LN-WTM series integrates a separation chamber, diaphragm-type low-temperature pressure sensor, storage chamber, tailpipe heating solenoid valve and other customer-customized requirements. It features cold-start temperature heating and has a water separation efficiency up to 95%. The water storage volume is available in 80ml/120ml, and it is equipped with a tailpipe heating solenoid valve to ensure reliable drainage in low-temperature environments. Optional purge valve and pressure sensor are supported.

Both series bodies are made of aluminum alloy, with a working temperature covering -40C~120C. All products undergo 100% functional test and helium leak test before leaving the factory and are fully traceable.
