摘要： An apparatus and method for measuring an electrochemical impedance at high speed. The method for measuring the electrochemical impedance of an electrolyte at high speed includes applying a direct current (DC) voltage having the reaction potential of the electrolyte to the electrolyte via a counter electrode and, after a delay, applying a signal voltage, including a DC voltage added to a differentiated or integrated Dirac-delta function voltage, to the electrolyte; computing a digital data value related only to the differentiated or integrated Dirac-delta function voltage, obtained by converting signal current flowing in a working electrode via the electrolyte into a voltage, integrating or differentiating the voltage, and Fourier transforming the result of the integration or differentiation; and obtaining changes in magnitude and phase as a function of frequency based on the Fourier transform, to compute the impedance. By investigating impedances computed at intervals upon the application of a reaction potential and upon the application of a step voltage plus the reaction potential to the electrolyte, the influence of mass transfer and electron transfer in the electrolyte on the impedance measurement can be understood.
