在水冷质子交换膜燃料电池（PEMFC）系统中，涉及协调冷却液循环泵和散热器风扇等热管理组件的热管理系统对于保持PEMFC的输出性能处于安全稳定的状态起着重要作用。为了避免冷却液温度波动、防止热失控，建立了基于电化学反应和热力学的面向控制的水冷系统热管理控制模型，并开发了实验系统进行模型验证。模型结果与三种不同工况（增大冷却液进出口温差、降低冷却液入口温度、增大输出电流）下的实验数据的比较表明，该模型能够有效、高精度地模拟输出电压、冷却液温度、冷却液流量和散热器控制电压变化的动态行为。因此，所提出的模型将指导水冷质子交换膜燃料电池控制系统的设计和优化。
In water-cooled proton exchange membrane fuel cell (PEMFC) system, a thermal management system which involves coordinating thermal management components such as the coolant circulation pump and radiator fan plays the important role for keeping the output performance of PEMFC in safe and steady condition. In order to avoid coolant temperature fluctuations and prevent thermal runaway, a control-oriented water-cooled system model based on electrochemical reactions and thermodynamic for the thermal management control is established and an experimental system is also developed for model validation. The comparisons between the model results and the experimental data under three different operating conditions (increasing the coolant temperature difference between outlet and inlet, reducing the coolant inlet temperatures, increasing the output current) demonstrate that the proposed model can efficiently simulate the dynamic behaviors with a high accuracy for the changing of the output voltage, the coolant temperature, the coolant flow rate and the controlling voltage of radiator. Therefore, the proposed model will be used as guidance for the design and optimization of the water-cooled PEMFC control system.
