四电极质子补偿法测量质子交换膜的电导率

Conductivity measure of proton exchange membrane with four-electrode proton compensation

对已有的质子交换膜电导率的测试方法进行了分析,针对影响准确测量电导率的因素而设计了一种四电极质子补偿测试法.结果表明,该方法与传统的四电极测试法相比,简单方便、精度较高,能有效地避开极化与测量时间的影响,具有广泛的实用性.

The principle and method about conductivity measure of proton exchange membrane(PEM) has been discussed in this paper. A four-electrode proton compensation is designed for conductivity measure, which can effectively eliminate polarization and measure time delay. The study shows that the method is not only simple but also suitable, overcoming some disadvantages of conductivity measure.
