针对质子交换膜燃料电池在不同放电状况下具有不同阻抗的特性
通过电化学阻抗谱法测量了单蛇形流场质子交换膜燃料电池在不同放电电流下的电化学阻抗谱图
并通过R(QR)等效电路模拟得到电池在不同工作状态下的电路元件参数.实验结果表明
由于随着放电电流的增大
电池内的水由少到多再到过量
从而引起电极上的反应过程由慢到快再变缓
因此电池内部的电荷转移电阻先减小后增大.在大电流情况下
由双电层充放电效应引起的附加阻抗比较明显
使得放电电流越大
电池的系统阻抗增大越显著
而在中等放电电流(5 A)时
电池系统的阻抗最小.
Considering the fact that proton exchange membrane(PEM)fuel cell has different impedance performances under different discharge currents
a PEM fuel cell with single serpentine flow field was investigated with electrochemical impedance spectroscopy
and the R(QR)equivalent circuit was used to calculate the circuit element parameters. The experimental results show that water in the fuel cell increases from insufficient to sufficient and then excessive with the increasing discharge current. Accordingly
the electrochemical reaction rate on the electrodes increases first and then decreases
thus the charge transfer resistance decreases and then increases. The impedance of PEM fuel cell increases obviously for high discharge currents due to the accessional impedance produced by double-layer effect
while the impedance reaches minimum at medium discharge current(5 A).
