Control and Application of High-Power Self-Humidification Fuel Cell System for Passenger Cars

摘要:

针对100 kW级乘用车燃料电池一体化系统，开发了一种高效、长寿命的系统控制器。结合Matlab/Simulink软件和Motohawk平台快速控制原型开发了完整的系统控制程序；以空气子系统为代表，讨论了控制器的闭环控制性能；通过开发FC系统控制器，研究了整个系统的动态性能。结果表明，FC系统在净功率、系统效率和一致性方面表现出极好的潜力。系统最高效率达到62%，电压变化系数（C_v）在负载动态变化期间控制在1%以下。

Abstract:

Proton exchange membrane fuel cell vehicles are an important technology route to achieve carbon neutrality in transportation. In this paper， a system controller was developed for high efficiency and long durability on an integrated 100 kW passenger car fuel cell system. The complete control program is developed in conjunction with Matlab/Simulink and the Motohawk rapid control prototype. Then， the closed-loop control performance of the controller was discussed， represented by the air subsystem. Finally， with the implementation of the FC controller developed， the dynamic performance of the entire system was studied. The results show that the FC system has an excellent potential in terms of net power， system efficiency， and consistency. The maximum efficiency of the system reaches 62%， and the voltage variation coefficient （Cv） is controlled below 1% during dynamic load changes.
