Abstract Water management of proton exchange membrane fuel cell (PEMFC) is critical to fuel cell performance. Appropriate PEMFC humidity can not only improve the performance and efficiency of the fuel cell, but also prevent irreversible degradation of internal compositions such as catalysts and membrane. In this paper, a dynamic water management model of PEMFC system is established, and an Active Disturbance Rejection Control (ADRC) strategy is proposed for balancing the cathode humidity of PEMFC. The simulation results show that compared with the traditional proportion integral derivative (PID) control and Fuzzy-PID control, the ADRC strategy can effectively shorten the response time, reduce the overshoot, improve the energy efficiency. Moreover, the performances of PEMFC using ADRC control strategy under different temperature and pressure condition are discussed. Furthermore, the power generation efficiency of PEMFC under ADRC humidity control is 2.36% and 1.48% higher than that of traditional PID and Fuzzy-PID control, respectively.

自抗扰控制策略应用于PEMFC系统阴极湿度控制

摘要 质子交换膜燃料电池 (PEMFC) 的水管理对燃料电池性能至关重要。适当的 PEMFC 湿度不仅可以提高燃料电池的性能和效率，还可以防止内部成分如催化剂和膜的不可逆降解。在本文中，建立了 PEMFC 系统的动态水管理模型，并提出了一种主动干扰抑制控制 (ADRC) 策略来平衡 PEMFC 的阴极湿度。仿真结果表明，与传统的比例积分微分（PID）控制和模糊PID控制相比，ADRC策略能够有效缩短响应时间，减少超调，提高能效。而且，讨论了采用 ADRC 控制策略的 PEMFC 在不同温度和压力条件下的性能。此外，ADRC湿度控制下PEMFC的发电效率分别比传统PID和Fuzzy-PID控制高2.36%和1.48%。
