燃料电池发动机系统多场耦合模型分析与温度控制方法
Analysis of Multi-Field Coupling Model and Temperature Control Method for Fuel Cell Engines
摘要
Abstract
Temperature control is crucial for achieving rapid response,reducing energy consumption,and ensuring the safe operation of fuel cell engines.The coupling characteristics of the internal thermal field,electrochemical field,and flow field are key factors in temperature control.This article focuses on a medium-sized fuel cell truck,constructing a"heat-electricity-flow"multi-field model.It establishes key temperature control factors through parameter analysis,designs a fuzzy PID temperature controller,and verifies the control effectiveness under various operating conditions.The results show that the constructed model can comprehensively analyze the key parameters of temperature control.The proposed controller effectively improves response speed,reduces the speed of the cooling fan and decreases output voltage overshoot.Under both the set test condition and the NEDC condition,the temperature overshoot is reduced by 19.1%and 1.64%respectively.This work provides a foundation for the design and control of fuel cell engines,further promoting the in-vehicle application of high-power fuel cell engines.关键词
