AI Technical Summary
While existing high-pressure fuel cell solutions improve performance, they also have drawbacks such as high cost, size, weight, and power consumption of air compressors, high temperatures, which increase system cost, size, and failure rate. Simultaneous increase in anode hydrogen pressure leads to high sealing requirements, and frequent pressure changes cause component fatigue, resulting in complex and costly systems.
It adopts a closed cathode structure, and the cathode air flow rate is independently regulated from the coolant flow rate. By optimizing the cathode flow channel design, the pressure drop and back pressure are reduced, and a low-pressure operation mode is adopted. A centrifugal blower is used to provide cathode airflow, eliminating the intercooler and back pressure valve, and using a common pressure reducing valve instead of an expensive proportional valve.
It achieves high current density under low pressure, reduces system cost, size and failure rate, reduces air compressor power consumption and heat, avoids component fatigue, simplifies system design, and reduces sealing costs and failure rate.
