AB - Vehicle fuel cell systems release a large amount of heat while generating  electricity. The suitable thermal management system must be built to ensure  system performance and reliability. Based on the analysis of the working  principle of the vehicle fuel cell thermal management system, the paper  establishes a control-oriented fuel cell thermal management. The stack, air  cooler, hydrogen heat exchanger, bypass valve, heat sink, and cooling water  circulating pump model are taking into account. System model, and the  relationship between stack current, coolant flow rate, fin surface wind  speed, bypass valve opening, and fuel cell temperature are in established in  simulation experiments. The paper discusses their effects on system as a  whole, air coolers, hydrogen heat exchangers, and the influence of the  temperature difference between the inlet and outlet of the radiator. The  simulation results can provide guidance and help to design the fuel cell  thermal management control system.
