Abstract
An ionic conductivity measurement device of an electrolytic membrane includes a humidification chamber configured to accommodate an ion-conductive electrolytic membrane and having concave grooves respectively formed at both sides thereof which face the electrolytic membrane to form a measurement space for measuring ionic conductivity of the electrolytic membrane; a plurality of channels formed at a bottom surface of each of the concave grooves; a gas distribution unit detachably coupled to each of the concave grooves with the electrolytic membrane being interposed therebetween; and a plurality of electrodes provided in contact with one side of the electrolytic membrane and supported by the gas distribution unit, the plurality of electrodes being disposed side by side to measure an impedance of the electrolytic membrane.
