Abstract

The invention discloses a test clamp for conductivity of a proton exchange membrane. The clamp is capable of combining an electrochemical workstation to test the conductivity of the proton exchange membrane by using a four-electrode method. The clamp is formed by upper and lower parts. The upper part is a four-electrode fixing frame, and comprises an upper seat and two voltage electrode fixing plates. The upper seat is opened with a membrane flat window and an observing window. The lower part is a proton exchange membrane support base. The base is provided with an electrode fixing contact column, a membrane flat window, an observing window and a waterproof condensation hole. The proton exchange membrane is installed between the four-electrode fixing plate and the support base to execute the conductivity test. The clamp can be suitable for the test of the low-temperature, intermediate-temperature and high-temperature proton exchange membrane conductivity, and suitable for the conductivity test under the conditions of deionized water and relative humidity atmosphere. The clamp has the advantages of simple design, convenient operation, and high measurement accuracy.
