摘要

该文对比了燃料电池发电系统电压和电流控制模式对燃料电池运行状态的影响,结合燃料电池系统效率优化需求,提出可实现最优效率跟踪的电压控制模式,同时解决了燃料电池运行到浓差极化区加速老化的问题和传统的最大效率优化算法过于复杂的问题。通过仿真分析,验证了恒压模式下的控制方式能够根据质子交换膜燃料电池（PEMFC）发电系统所需功率的实时变化而自动地进行过氧比调节,满足最优效率的性能指标要求,提高系统的运行效率与稳定性。

Abstract

This paper compares the impacts of the voltage and current control modes of the fuel cell power generation system on the operating state of the fuel cell. Combined with the requirements for optimizing the efficiency of the fuel cell system, a voltage control mode that can achieve optimal efficiency tracking is proposed. Meanwhile, it solves the problems of accelerated aging when the fuel cell operates in the concentration polarization region and the excessive complexity of the traditional maximum efficiency optimization algorithm. Through simulation analysis, it is verified that the control method under the constant voltage mode can automatically adjust the oxygen excess ratio according to the real-time changes in the required net power of the PEMFC system. Moreover, under the working conditions with large dynamic changes in the load current, it can meet the performance index requirements of the optimal efficiency and improve the operating efficiency and stability of the system.
