APPARATUS FOR ESTIMATING WETTABILITY OF ELECTROLYTE IN ELECTROCHEMICAL SYSTEM INCLUDING POROUS ELECTRODES AND METHOD THEREOF

摘要

An apparatus for estimating wettability of electrolyte in electrochemical system is provided to measure wettability of the electrolyte of the electrochemical system in short time by using an electrochemical method. An impedance measuring unit(11) measures the impedance of the electrochemical system by applying AC voltage to an electrochemical system. A microprocessor(13) receives for each frequency impedance data from the impedance measure method, and the microprocessor calculates the parameter which is for each frequency impedance data fine to the equivalent circuit including the constant phase element. Microprocessor outputs the wettability of the electrochemical system with parameter to the quantized value.
