| 摘 要： | 在已有的质子交换膜燃料电池系统模型基础上添加气体扩散层模型和膜电极组件动态模型,研究膜中水含量的动态特性.仿真结果表明,系统动态模型改进之后其输出性能与实验值误差较小,能够反映外部操作条件变化对电池内部电化学反应和物料传递过程的影响,膜中水含量和输出性能的动态响应过程更加接近实际情况,相关信息可用于间接控制膜中水含量和优化系统.

| Abstract: | To investigate dynamical behaviors of membrane water content in a proton exchange membrane fuel cell (PEMFC), a dynamic system model was established, consisting of a gas diffusion layer (GDL) and a membrane electrode assembly (MEA). The simulation results show that there is a small difference between the outputs of modified PEMFC system model and experimental data. The dynamic influence of the water content on stack voltage is plausible under more realistic operating condition. The effect of manipulating variables on chemical reaction and transfer process can also be refluxed by the modified PEMFC system model which can be used to control and analyze the membrane water content and optimize a PEMFC system. |
