本文分析了燃料电池混合动力系统在铁路上的不同用途。四辆车在合适的轨道上进行了数值测试。所实现的模型从轨道高度、列车速度和车辆特性出发，计算车辆的动力需求。对于每条轨道，使用一个由燃料电池系统和一个能量存储系统、电池和/或超级电容器组成的动力系统，适合于这一目的。每个组件分别建模并进行验证。应该强调的是，通过文献中的实验数据，整个系统得到了验证。对仿真结果进行了对比分析：根据轨道能耗，H-2的消耗在5kg /cycle ~ 160kg /cycle之间，而由于燃料电池工作在不同的功率下，燃料电池的效率在50% ~ 47%之间。(C) 2019氢能源出版有限责任公司，由爱思唯尔有限公司出版。版权所有。
This paper analyses the use of a fuel cell hybrid powertrain for different uses on rail. Four vehicles are numerically tested on suitable tracks. The implemented model calculates the vehicle power demand, starting from track altitude, train speed and vehicle characteristics. For each track, a powertrain composed of a fuel cell system and an energy storage system, battery and/or supercapacitor, is used, suitable for the purpose. Each component is modelled separately and is validated. It should be underlined that the whole system is validated, by means of experimental data found in the literature. A comparison analysis between the simulation results is done: the H-2 consumption varies between 5 kg/cycle and 160 kg/cycle, according to the track energy consumption, while the fuel cell efficiency is between 50% and 47%, since the fuel cell works at different power rates.
