A. Bautista et al., Noise resistance applied to corrosion measurements - V. Influence of electrode asymmetry, J ELCHEM SO, 148(10), 2001, pp. B412-B418
The significance of electrochemical noise measurements in cells containing
two identical electrodes kept at the same potential has been clearly establ
ished. However, when the electrodes are of different materials or when a bi
as voltage is applied between them, it is not clear what information the me
asurement of the noise impedance yields. The purpose of this paper is to de
velop the theory of asymmetric cell measurements, and to compare the predic
tions of the model with experimental results obtained for four asymmetric s
ystems. (C) 2001 The Electrochemical Society.
