摘要
针对大功率车用燃料电池发动机的氢气系统进行建模,基于MATLAB/Simulink平台搭建氢气系统核心部件模型及其控制模型,并集成氢气系统整体模型,基于该模型进行2种常见汽车行驶工况—CLTCP和NEDC工况的动态仿真,结果表明,所建控制模型能较好保证阳极入口压力满足工作压力需求,并将阴极和阳极的压差维持在0.02 MPa,2种工况的氢气利用率分别为99.67%和99.76%,表明该模型可以用于大功率车用PEMFC系统开发。
The model of hydrogen system of high-power fuel cell engine is designed,the core components and control system of hydrogen system are modeled and simulated in MATLAB/Simulink platform.Based on the hydrogen system model,the CLTCP and NEDC common driving conditions are simulated on dynamic.The results showed that the anode working pressure requirements could be guaranteed by the inlet pressure,and the pressure difference between cathode and anode was maintained in 0.02 MPa.The hydrogen utilization rate of the two conditions were 99.67% and 99.76% respectively.That means the model can be used in the development of high-power vehicle PEMFC system.
