摘　　要：为分析燃料电池的动态特性,对其发电和发热过程进行了建模研究。燃料电池划分为阳极动态模型、阴极动态模型、电化学电压模型和温度动态模型,分别从流量平衡、能量平衡和经验公式角度进行了机理建模;并采用改变负载和冷却水流量的方式进行测试。仿真结果表明,该模型能模拟燃料电池的电热动态过程,可用于辅助控制设计。In order to analyze the dynamic characteristics of the fuel cells,the modeling research on their electricity and heat generation processes is conducted.The fuel cells are determined into four types of models： anode dynamic model,cathode dynamic model,electrochemical voltage model and temperature dynamic model;the mechanism model is set up from flow balance,energy balance and experience formula,and the model is tested by adopting changing load and cooling water flow.The simulation result demonstrates that the model can emulate electric and heat dynamic process and can be used in auxiliary control design.
