【Abstract】 The methods about measurement of ionic conductivity of proton exchange membrane were introduced briefly.The normal component of conductivity was measured by two-probe ac impedance spectroscopy.The results show that the conductivity of proton exchange membrane can be measured exactly after being sealing and zero correcting of equipment resistance,and the conductivity at subzero temperature can be measured successfully.更多还原
