Abstract
⺠A model is developed that simulates exchange of hydrogen isotopes in a spherical metal hydride particle. ⺠Diffusion depends on the concentration gradients of both isotopes in addition to the site vacancies. ⺠Thermodynamic coupling is derived from the Gibbs free energy of mixing and the excess chemical potential. ⺠Unknown diffusion coefficients are determined by fitting to available experimental data. ⺠Example calculations illustrate times required for isotope exchange.
