title: Hydrogen transport in non-ideal crystalline materials.
abstract: Hydrogen-transport behaviour under (non-)isothermal conditions is discussed. An extended modelling approach based on the effective diffusion coefficient is outlined for arbitrary temperature programmes, defect properties and hydrogen-loading pressures. The influence of mathematical terms, such as the trap equilibrium reaction or microstructural changes, is critically discussed and examples of thermal desorption spectra and isothermal diffusion behaviour are given.
