摘要
对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。研究结果表明,该方法与通常采用的四电极测试法相比,简单方便、精度高,能有效地避开极化与测量时间的影响。
The principle and method about conductivity measure of proton exchange membrane(PEM) has been discussed in this paper. Of those the four-electrode proton compensation is designed for conductivity measure, which can effectively eliminate influence of polarization and measure time.Comparised with the former method,the new method not only is simple and suitable,but also can make up some disadvantages of conductivity measure,such as the effects of polarization and measure time.
