摘要

动态特性是影响质子交换膜燃料电池性能的关键问题之一。通过对直通道质子交换膜燃料电池进行简化建模，选取合适的参数进行数值计算，比较不同电流密度加载时间以及加载幅度的情况下，燃料电池的电压和正负极气体浓度响应情况，进而研究燃料电池动态加载特性。结果表明：增加电流密度加载过程时间同时减小加载幅度，有利于提高电池的稳定性，延长电池寿命。变载时，阴极达到稳定所需的时间更短。

Abstract

Background

Dynamic behavior is one of the most critical issues for proton exchange membrane fuel cells.

Purpose

This study aims to understand the dynamic characteristics which is conducive to the rational design and control of fuel cells.

Methods

In this paper

a simplified modeling of the direct channel proton exchange membrane fuel cell is carried out

and the appropriate parameters are selected for numerical calculation. Response of fuel cells is analyzed in different load time and load amplitude numerically.

Results

The trend curves of loading amplitude

loading time and reaction gas concentration are obtained.

Conclusion

The results show that it is beneficial to improve the stability of fuel cell by increasing the load time and decreasing the load amplitude. And it takes less time to reach stability for the cathode than the anode when the load is changed.
