Analysis of Radiation Induced Phenomena in a Polymer ElectrolyteMembrane with Positron Annihilation Technique

摘要：

Degradation of polymer electrolyte membrane (PEM), appearing as the reduction of generation voltage, proton conductivity and the lack of mechanical strength, has been investigated to improve durability. In this study, we focused on the reduction of proton conductivity in PEM, since the initial change in degradation is thought to appear in proton conductivity. The proton conductivity must be affected by the electronic state near the ion exchange site, namely hydrophilic site, as well as the structure of nanoscale spaces.
