The mechanism of oxygen permeation through an ionomer of polymer electrolyte membrane fuel cell (PEFC) was not analyzed in detail and it is too difficult to research by experiment. Moreover molecular dynamics simulation of the structure of catalyst layer and oxygen permeability has not yet reserched. We made the system including nafion, water, oxonium ion, nanoparticle platinum on a carbon layer by using molecular dynamics study, and researched about the structure of ionomer and the permeability of the oxygen molecule.
