摘要
建立了质子交换膜燃料电池(PEMFC)动态模型,分析在负载突变情况下PEMFC输出电压的动态响应特性。根据PEMFC电化学特性建立其稳态经验公式模型,利用实验数据确定模型中的相关经验参数,使得模型仿真结果与实验结果具有较高的吻合度。在PEMFC稳态模型的基础上结合理想气体状态方程的微分形式建立了PEMFC动态模型。通过设置负载阶跃,观察燃料电池动态响应特性,并设计相关实验进行验证。结果表明该动态模型能够较好地模拟燃料电池实际动态响应过程。
A dynamic model of proton exchange membrane fuel cells(PEMFC)is established to analyze the dynamic response characteristics of the output voltage of PEMFC under sudden load changes.According to the electrochemical characteristics of PEMFC,the steady-state empirical formula model is established,and the relevant empirical parameters in the model are determined using experimental data,so that the simulation results of the model and the experimental results have a high degree of agreement.Based on the steady-state model of PEMFC combined with the differential form of the ideal gas state equation,a dynamic model of PEMFC is established.The dynamic response characteristics of the fuel cells is observed by setting the load step,and related experiments are designed for verification.The results show that the dynamic model can better simulate the actual dynamic response process of the fuel cells.
