摘　　要：简单介绍了质子交换膜电导率的测试方法,选用交流两电极法测量了质子交换膜法线方向的电导率,结果表明,经过密封和装置电阻的零点校正可准确测量出质子交换膜电导率,并成功测量了质子交换膜零度以下的电导率。The methods about measurement of ionic conductivity of proton exchange membrane were introduced briefly. The normal component of conductivity was measured by two-probe ac impedance spectroscopy. The results show that the conductivity of proton exchange membrane can be measured exactly after being sealing and zero correcting of equipment resistance, and the conductivity at subzero temperature can be measured successfully.
