摘要
为解决质子交换膜燃料电池发动机在功率变化时热管理系统温度不稳定、进出口冷却液温差大等问题,使用LMS AMESim仿真软件,以30 kW质子交换膜燃料电池发动机为基础,考虑整车的功率变化和驾驶员需求等因素,建立质子交换膜燃料电池发动机热管理系统模型。使用燃料电池发动机标定工况来分析热管理系统各个部件的冷却液温度和压力情况;采用新欧洲驾驶循环(NEDC)工况进行质子交换膜燃料电池热管理仿真测试。结果表明,所建立的热管理系统可以在NEDC工况下保持温度稳定,进出口冷却液最高温差约为5.6℃,可为质子交换膜燃料电池发动机热管理试验研究及测试提供一定的依据和指导。
To solve the problems of unstable temperature of thermal management system and large coolant temperature difference between inlet and outlet when the power of proton-exchange-membrane fuel cell(PEMFC)changes,using LMS AMESim simulation software,a thermal management system model of PEMFC engine was proposed based on a 30 kW PEMFC engine,considering factors including the power change of the whole vehicle and the driver’s demand.Firstly,the fuel-cell engine calibration condition was used to analyze the coolant temperature and pressure of each component of the thermal management system.Secondly,the New European Driving Cycle(NEDC)was used to simulate the PEMFC thermal management.The results show that the established thermal management system can keep the temperature stable under NEDC working condition,and the maximum temperature difference between inlet and outlet coolant is about 5.6℃.This simulation analysis can provide guidance for the thermal management test research of PEMFC engine.
