摘要:
为提高质子交换膜燃料电池内部温度的均匀性，并实现对冷却系统模型的精准控制，设计了一种Y型树状分形冷却流道。利用Fluent软件对带有冷却流道的单电池进行数值模拟，分析了冷却水温度及流量对质子交换膜表面温度分布和单电池极化曲线的影响。同时，利用Simulink搭建PID控制器和自抗扰控制器（ADRC）模型，分别对电堆温度进行控制，并对比分析了二者控制效果的优劣。结果表明：当冷却水质量流量为1 g/s时，333 K的冷却水比298 K的冷却水对燃料电池的冷却效果更佳，质子交换膜表面温差更小，温度分布也更均匀；当冷却水温度为室温298 K、质量流量为1.5 g/s时，达到最大电流密度0.440 3 A/cm2；当冷却水预热至343 K、质量流量为6 g/s时，达到最大电流密度0.476 8 A/cm2；ADRC的控制效果优于PID控制器，当负载电流3次阶跃变化时，ADRC调节电堆温度的超调量比PID控制器分别减小了62.5%，56.2%和46.6%，调节时间分别减小了10.32，18.46和24.18 s。
Abstract:
A Y-shaped tree fractal cooling channel was designed to improve the internal temperature uniformity of proton exchange membrane fuel cells and to achieve precise control of the cooling system mode. Numerical simulation of a single cell with a cooling channel was carried out using the Fluent software, and the effects of the coolant water temperature and flow rate on the surface temperature distribution of the proton exchange membrane and the polarization curve of the single cell were analyzed. Meanwhile, a PID controller model and an active disturbance rejection controller (ADRC) model were built using Simulink to control the temperature of the cell stack, and their advantages and disadvantages were compared. The results showed that when the coolant water mass flow rate is 1 g/s, the cooling effect of 333 K coolant water on the fuel cell is better than that of 298 K coolant water. The smaller the temperature difference on the surface of the proton exchange membrane is, the more uniform the temperature distribution is. When the coolant water temperature is 298 K, and the mass flow rate is 1.5 g/s, the maximum current density is 0.440 3 A/cm2. When the coolant water is preheated to 343 K, the mass flow rate is 6 g/s, the maximum current density is 0.476 8 A/cm2. The control effect of the ADRC controller is better than that of the PID controller. When the load current changes in three steps, the overshoot of the ADRC controller is 62.5%, 56.2%, and 46.6% less than that of the PID controller, and the regulation time is 10.32, 18.46, and 24.18 s shorter than that of the PID controller, respectively.
