Abstract

The electrochemical noise of a solid polymer air–hydrogen fuel cell was measured at different loads. Some of the common approaches to data treatment of electrochemical noise were tested. The dependences of the standard deviation and second and third central moments on the constant load current were calculated. The distribution diagrams were constructed. The spectral power density was calculated by Fourier transform using the wavelet transform and also through the standard deviations in the given frequency band. The data calculated by different methods were in good agreement.

空气-氢燃料电池电化学噪声分析方法的比较

摘要

固体聚合物空气氢燃料电池在不同负载下的电化学噪声被测量。测试了一些电化学噪声数据处理的常用方法。计算了标准偏差和第二，第三中心矩对恒定负载电流的依赖性。绘制了分布图。通过使用小波变换的傅里叶变换并通过给定频带中的标准偏差来计算频谱功率密度。不同方法计算得到的数据吻合良好。
