【Abstract】 The electrochemical properties of perfluorosulfonic acid membrane can reflect the quality of the membrane and are important factors for the correct use of the membrane. An instrument of four-electrode system was designed for testing electrochemical properties of perfluorosulfonic acid membrane. Three basic electrochemical properties of the membrane, conductivity, potential and dielectric constant, can be tested with constant potential and constant current methods. The corresponding electric circuits are described. The electrochemical properties of NX901 membrane were tested.更多还原
