Molecular dynamics analysis of hydriding / dehydriding of palladium hydrides Part II: Surface / interface thermodynamic and kinetic properties

Journal Article Zhou, Xiaowang ; Allendorf, Mark D. ; Stavila, Vitalie ; ...

This paper uses molecular dynamics simulations to study surface and interface properties of PdH_x that are relevant to hydrogen storage applications. In particular, surface energies, interfacial energies, surface diffusivities, and surface segregations are all determined as a function of temperature and composition. During the course of the calculations, we demonstrated robust molecular dynamics methods that can result in highly converged finite temperature properties. Challenging examples include accurate calculations of hydrogen surface diffusivities that account for all possible atomic jump mechanisms, and constructions of surface segregation composition profiles that have negligible statistical errors. Our robust calculations reveal that the Arrhenius plotsmore »« less

Modeling of temporal behavior of isotopic exchange between gaseous hydrogen and palladium hydride power

Technical Report Melius, C F ; Foltz, G W

A parametric rate-equation model is described which depicts the time dependent behavior of the isotopic exchange process occurring between the solid and gas phases in gaseous hydrogen (deuterium) flows through packed-powder palladium deuteride (hydride) beds. The exchange mechanism is assumed to be rate-limited by processes taking place on the surface of the powder. The fundamental kinetic parameter of the model is the isotopic exchange probability, p, which is the probability that an isotopic exchange event occurs during a collision of a gas phase atom with the surface. Isotope effects between the gas and solid phases are explicitly included in termsmore »« less
