“…Gierst and Mechelynck have reported upon a general chronopotentiometric study of aqueous systems (11). Nicholson and Karchmer applied the method to a determination of lead in nitric acid (15). Finally, certain titration end points have been detected by chronopotentiometric means (19).…”

“…The potentialities as an analytical technique were pointed out by Reilley, Everett, and Johns (14). Nicholson and Karchmer obtained excellent results in routine determinations of lead ion (12). Gierst has recently reported on equipment for chronopotentiometry capable of very rapid results with high pre-cisión (4).…”

“…This is because, when a constant potential is applied for a long period, the current decays down to a steady value, which provides a stable condition for AC potential applications. However, when a current is applied for a long time, the steady potential is reached but is interrupted by a potential jump at the transition time. ,, The sudden change of potential activates additional reactions which are not of interest. The transition time also limits the number of applied AC frequencies.…”

Here, we report development of the galvanostatic Fourier transform electrochemical impedance spectroscopy (FTEIS), which monitors impedance of electrochemical reactions activated by current steps. We first derive relevant relations for potential change upon application of a step current, obtain impedances theoretically from the relations by simulation, and verify them with experimental results. The validity of the galvanostatic FTEIS technique is demonstrated by measuring impedances of a semiconductive silicon wafer using the conventional frequency response analysis (FRA), the potentiostatic FTEIS, and the galvanostatic FTEIS methods, and the results are in excellent agreement with each other. This work is significant in that the galvanostatic FTEIS would allow one to record impedance changes during charge/discharge cycles of secondary batteries and fuel cells as well as electrochemically irreversible systems which may produce noise level chronoamperometric currents by potentiostatic techniques.
