摘要：

The problem of non-stationarity plays an important role in the development of impedance spectroscopy. The main reason is due to the fact that most electrochemical systems possess an intrinsic non-stationary nature. Instantaneous impedance is the theoretical basis for solving this problem. The present paper is devoted to an experimental technique for estimation of the instantaneous impedance. On the basis of the four-dimensional approach the experimental design for measuring the instantaneous impedance is described in detail. A special technique is proposed for validation of the modelling, based on the a posteriori evaluation of the model flexibility.
