ELECTROCHEMICAL ANALYSIS APPARATUS AND ELECTROCHEMICAL SYSTEM

摘要

An electrochemical analysis apparatus 1 includes a power controller 20 that generates a rectangular wave signal having a first frequency (f1) and applies the rectangular wave signal to an electrochemical cell 10 including a plurality of electrodes 11 to 13 and an electrolyte 14, a Fourier transform section 30 that Fourier-transforms a response signal of the electrochemical cell 10 to the rectangular wave signal and calculates frequency characteristics including a component of a second frequency f2 of an integer multiple of the first frequency f1, and a calculating section 40 that calculates an impedance characteristic of the electrochemical cell 10 based on the frequency characteristics calculated by the Fourier transform section 30.
