摘要
车用燃料电池系统耐久性是制约燃料电池汽车发展的技术瓶颈之一。汽车运行工况复杂多变,燃料电池系统内部温度、湿度、压力等运行参数控制难度较大,且处理不当会加剧电堆寿命衰减。本文立足于车用燃料电池系统电控技术,分析了不同的运行工况和运行参数的波动对燃料电池性能衰退的影响,并对燃料电池系统组成、结构、控制器硬件、控制目标和常用管控策略等进行了介绍。总结出,通过功率调节与车载储能装置进行能量分配和功率控制,并结合基于模型的燃料电池系统控制方法可更好地实现温度、湿度、压力等运行参数的管控,保证燃料电池处于合适工作条件,延长使用寿命。最后,展望了车用燃料电池系统电控技术的发展趋势。
Fuel cell system durability is one of the technical bottlenecks restricting the development of fuel cell vehicles. Vehicle operating conditions are complicated and varied,the operating parameters of fuel cell system like temperature,humidity and pressure,are difficult to control,and the improper handling may aggravate the decay of battery stack. In this paper,from the standpoint of the electric control of automotive fuel cell system,the effects of the fluctuation of operation conditions and parameters on the performance degradation of fuel cell are analyzed,and the composition,structure,controller hardware,control objective and common control strategies of fuel cell system are presented. It is concluded that the energy distribution and power control by power adjustment and onboard energy storage device,combined with model-based control scheme can better achieve the control of operation parameters such as temperature,humidity and pressure,ensuring the fuel cell working in suitable conditions for extending its service life. Finally,the development trends of electric control on vehicular fuel cell system is summarized and forecasted.
