The considered problem is a part of the general problem of fluctuation and noise studies of chemical current sources. The measurements were made on a chain of two identical elements, providing mutual compensation of the constant component. The recorded noise signal covered a range from 10 Hz to 1200 Hz. It was found that the analyzed signals are stationary Gaussian random noise with a nearly uniform spectrum. It is shown that the studied noises can be identified as Johnson noises arising from the resistive impedance of the chemical current source.
