Abstract

The mathematical model of the auxiliary heat dissipation system for vehicle PEMFC is established, and the pipeline connection modes of the auxiliary heat dissipation system for the PEMFC engine system of a vehicle are designed. The flow resistance of the pipeline, coolant flow rate and coolant temperature rise are analyzed, and experiment is carried out to verify the mathematical model. The results show that the mathematical model is accurate and reliable which can be used to design and optimize the pipeline connection mode of PEMFC auxiliary heat dissipation system. Under the same total coolant flow rate, the total flow resistance of the pipeline of the three-way parallel solution （air compressor controller - air compressor ontology） || （step-down DCDC- booster DCDC） || （hydrogen pump controller） is 40.7% lower than that of the two-way parallel solution （hydrogen pump controller - air compressor controller - air compressor ontology） || （step-down DCDC- booster DCDC）. The coolant flow rate of each branch pipeline meets the heat dissipation requirements of components, and the temperature rise of the coolant also meets the heat dissipation requirements of the vehicle.
