运行客车上的辅助系统所需的功率，例如用于空调和高级车辆控制的辅助系统，减少了配备有混合动力传动系的车辆的行驶里程。在实际的驱动条件下，与驱动单元的额定功率相比，在低功率水平下需要大量的附加能量。在本研究中，我们考虑一个燃料电池-电池驱动列车增强车载燃料（乙醇）处理器，以提供汽车的电动机的功率要求。使用系统的驾驶循环模拟，考虑到模拟负载条件下车载电源的功率重量比，能量重量比和功率效率比因素，我们表明，一个简单操作的紧凑型乙醇重整器，低功率电池由过量的重整器容量连续充电，高功率燃料电池由保守供电-来自汽缸的使用过的氢可以将混合燃料电池传动系统的范围增加到大约750公里。虽然三向混合动力的总能耗高于燃料电池-电池混合动力，但较少使用储存的氢气提高了混合动力传动系统的燃料经济性。虽然系统的复杂性增加，远程遇险模式操作变得可行与添加的燃料处理器。(C)2019年氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Power required to run auxiliary systems on a passenger car, such as those for air conditioning and advanced vehicle control, reduces the driving range of a vehicle equipped with a hybrid drive train. Under practical driving conditions, a significant amount of additional energy is required at low power levels compared to the rated power of the drive unit. In the present study, we consider a fuel cell-battery drive train augmented by an on-board fuel (ethanol) processor to provide the motoring power requirements of a car. Using systematic driving cycle simulations that take account of power-to-weight, energy-to-weight and power-to-efficiency factors of on-board power sources under simulated load conditions, we show that a combination of steadily-operated compact ethanol reformer, a low-power battery continuously charged by excess reformer capacity and a high-power fuel cell powered by conservatively-used hydrogen from cylinder can increase the range of hybrid fuel cell drivetrains to about 750 km. Although the overall energy consumption of the three-way hybrid is more than that of fuel cell-battery hybrid, lesser use of stored hydrogen improves the fuel economy of the hybrid drivetrain. While the system complexity is increased, long-range distressed mode operation becomes feasible with the added fuel processor. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
