Abstract
In this study, the mechanical properties of the polymer electrolyte membrane according to the temperature were studied. The test specimens of polymer electrolyte membrane were heat treated at 40℃, 60℃, 80℃, 100℃, and 120℃, and then the tensile tests were performed. As results of this study, the residual stress of the polymer electrolyte membrane was removes by the heat treatment and the elastic modulus decreased due to the decrease in internal energy. In addition, in the plastic region, the mechanical properties and crystallization rate of the polymer electrolyte membrane increased in proportion according to increase of the heat treatment temperature.
