HYDROGEN FUEL CELL SYSTEM, THERMAL MANAGEMENT METHOD AND RAIL TRANSIT VEHICLE

Abstract

The present invention describes a hydrogen fuel cell system, a thermal management method, and a rail transit vehicle. The hydrogen fuel cell system comprises a hydrogen fuel cell module, a solid-state hydrogen storage module, and a thermal management module connected to the hydrogen fuel cell module and the solid-state hydrogen storage module, respectively. The hydrogen fuel cell module comprises a main module and an auxiliary module, wherein a main thermal management module is installed between the main module and the solid-state hydrogen storage module, and an auxiliary thermal management module is installed between the auxiliary module and the solid-state hydrogen storage module.The heat required for the release of hydrogen from solid-state hydrogen storage comes from the waste heat of the hydrogen fuel cell module, reducing the load on a main circuit water-air radiator, decreasing the energy of a main circuit cooling fan and improving the system's energy utilization by more than 10%.
