title = "Molecular simulation of oxygen solubility and diffusivity in ionomer on Pt surface",
abstract = "We analyzed the oxygen permeability through the ionomer on the Pt surface using molecular dynamics simulations. We calculated the density distributions of ionomer components and oxygen, the number of permeated oxygen through the ionomer, and the oxygen solubility. As a result, we have found that the oxygen permeability decreases as water content increases. In the ionomer/gas interface and the bulk region, the oxygen solubility decreases. Beside, compared with the structure properties of bulk membranes, the oxygen diffusivity is considered to increase as water content increases due to the swelling of the regions. In the ionomer/Pt interface, the oxygen solubility decreases with increasing water content, besides it is considered that the oxygen diffusivity decreases with increasing water content, because the solvent fills the pores which are pathways of oxygen.",
