Proton conductivity of Nation membrane has been thought to be affected by the cluster structure of the membrane. We applied Small-Angle Neutron Scattering (SANS) under in-situ condition (T = 353 K, R.H. = 0, 20, 40, 60 and 70 %) and the simulation of Dissipative Particle Dynamics (DPD) to clarify the relationship between the cluster structure and molecular structure. We evaluated two types of Nafion membrane with has different molecular structure; 1) N115, 2) NE151F. We found/confirmed that there were three different sized periodic structures in the Nafion membrane, this periodicity was affected by molecular structure and cluster structure was swelled by humidity increase. We also obtained similar results by DPD. We conclude that the shift of scattering curve at q=0.2[Å-1] suggest swelling of cluster structure.
