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.
