Abstract

The invention discloses a conductivity representing device for a proton exchange membrane, which is used for quickly measuring the conductivity of the proton exchange membrane through the combination with an electrochemical workstation or an alternating-current impedance tester, and includes a fixing rack, membrane fixtures and a pressure device, wherein the fixing rack is formed through assembling an upper bottom plate, a lower bottom plate and two supporting screws; the membrane fixtures are at least in one group and are made of insulating material plates; each group of the membrane fixtures includes two clamping plates tightly overlapped and combined; the proton exchange membrane whose conductivity is to be tested and an electrode to be tested are placed between the two clamping plates of each group of the membrane fixtures; and the pressure device includes a pressing screw, a pressing buffer plate and a spring. Accurate testing result can be obtained through adjusting measurement parameters of the device to be matched with various proton exchange membranes with different proton conductivity for use, so that the measuring requirements of proton exchange membranes with different proton conductivity ranges can be met; and the device has the advantages of ingenious design, stable structure and stronger practicability.
