面对环境危机和能源危机，燃料电池车以无污染、能量转化率高等特性成为未来道路交通的理想解决方案。然而由于受到气、水、电多子系统间强耦合关系以及频繁突变的动态工况的影响，燃料电池车辆动力系统耐久性差、故障率高。为此，本项目拟从研究动态工况下燃料电池电堆性能衰减规律入手，提出考虑电堆耐久性约束的燃料电池发电系统控制策略，对车用燃料电池系统与车辆动力系统进行一体化建模与控制。据此，提出燃料电池车辆动力系统在线故障诊断与健康状态监控的方法，开发燃料电池车辆动力系统半物理仿真平台并对一体化建模与控制方法进行验证，实现燃料电池车辆动力系统耐久性、动力性、经济性多目标一体化动态协调优化控制，为提升我国燃料电池车辆可靠性和经济性奠定理论与技术基础。

Under the background of the environmental crisis and the energy crisis, fuel cell vehicles are considered to be an ideal solution for future zero emission and high efficiency transportation. However, fuel cell vehicles currently have poor durability and a high failure rate due to the strong coupling between its subsystems (gas, water and electrical subsystems) and the impact of the dynamic load. This project is proposed to (i) study the decay mechanism of the fuel cell stack under the dynamic load, (ii) propose a control strategy for the fuel cell systems considering the durability constraint of the fuel cell stacks, (iii) unify the modeling and control of the vehicular fuel cell systems and the vehicle dynamic systems, (v) propose an algorithm for online fault diagnosis, health monitoring, and (vi) develop a hardware-in-loop simulation platform to test and verify the performance of the unified modeling and control. A dynamically optimally coordinating control with multiple objectives (durability, dynamics, and economy) will be achieved in this project to lay the theoretical and technological foundation for the nation’s ultimate improvement of the reliability and economy of fuel cell vehicles.
