“…When the speed reaches a particular value, the speed will continue to increase, and the stack temperature will almost remain unchanged. Simultaneously, as the rotation speed increases, the temperature difference between the exit and the stack entrance can be reduced [8]. In the case of ignoring the air and hydrogen flow fields in the stack, according to the law of thermodynamics, when the stack temperature is stable, the heating power taken by the coolant is equal to the heating power generated by the stack: When the stack current is 200 A, and the temperature is 65 °C, the stack's thermal power is 69.19 kW.…”

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.
