Determination of the Surface Diffusion Coefficient of Hydrogen Atom on a Platinum Plane
This Paper describes an experimental method that established a local Pt/Nafion interface on the Platinum Plane, so that the boundary conditions and the initial condition of the (diffusion equation about the diffusion of adsorbed hydrogen atom the platinum plane can be controlled. The average diffusion coefficient of underpotential deposition of hydrogen on a surface of platinum was obained for the first time and D=1.50 ×10-4cm2•s-1.The accuracy of the datum was discussed.
