title = "Molecular dynamics simulation of oxygen diffusivity, solubility, and permeability in ionomer on Pt surface",
abstract = "We analyzed the dependence of the structure properties and the permeation properties of oxygen molecules in ionomer on water content. We constructed a system in which oxygen molecules permeated ionomer on a Pt surface. The ionomer/gas interface, bulk region, and ionomer/Pt interface were defined based on the density distribution of ionomer at each water content. Furthermore, the oxygen diffusivity, solubility, and permeability in each region of the ionomer were evaluated to analyze the oxygen permeation properties. As a result, the oxygen permeability in the ionomer/Pt interface is the lowest, for all water content. Moreover, comparing the contributions of the oxygen diffusivity and solubility to the oxygen permeability, it was found that the oxygen solubility plays a dominant role in the oxygen permeability, indicating that the oxygen solubility in the ionomer/Pt interface is the dominant factor in the oxygen permeability in the ionomer.",
