摘要
介绍了燃料电池的经验模型、电化学模型和电压动态模型,并通过Matlab/Simulink仿真工具对这三种模型进行仿真。对比分析了PEMFC电化学模型和电压动态模型在负载电流发生阶跃变化时,电池输出电压、输出功率和效率的响应情况,进一步诠释了PEMFC的工作状态与机理,通过分析有助于PEMFC的模型优化以及控制器设计。
The experimental model, electrochemical model and dynamic model were explained and these three models were simulated by the Matlab/Simulink simulation tool. The response of the output voltage, output power, and efficiency of electrochemical model and dynamic model were compared when the load current of electrochemical model and dynamic model had a step change. The working principle of PEMFC was explained further, which was helpful for the model optimization and controller design of PEMFC.
