摘要: This paper is aiming to estimate the mutual influences of the stack cooling performance with the operation modes of the thermal management system for the hydrogen fuel cell vehicles.The heat capacity of the thermal management system was measured by varying the operating modes such as stack cooling heat exchanger only(Mode 1),stack cooling and electric devices cooling heat exchangers(Mode 2),and stack cooling and electric devices cooling heat exchangers with an operation of the condenser(Mode 3).As the results,performance of the thermal management system(TMS)at Mode 3 decreased up to 34.0%,compared with the result of the Mode 1.When compared between real road test and laboratory test using cooling module tester with respect to heat dissipation rate of the radiator,error ratio based on real road test data was 1.83%at 70 km/hr of driving speed and 3.58%at 100 km/hr of it,respectively.Fabricated cooling module tester was thought to be reasonable to predict performance characteristics under real road driving conditions.
