摘　　要：在氢耗量稳态特性模型基础上,通过试验研究,建立了燃料电池发动机氢耗量半经验动态模型,并对模型进行了试验验证。结果表明,该模型能反映燃料电池氢耗量的动态特性,精度较高,而且该模型具有结构简单,模型参数较少等特点,通过较少的试验数据即能获得模型中的参数,便于在车辆动力学仿真研究中应用。Based on a steady-state hydrogen consumption model, a semi-empirical dynamic model for the hydrogen consumption of a fuel cell engine is developed and verified by test. The results show that the model can well reflect the dynamic characteristics of hydrogen consumption in fuel cell engine with high accuracy, simple structure and less parameters. The parameters of the model can be obtained from less test data, and hence is easy to be applied to the study on vehicle dynamics simulation.
