The nonlinear inverse problem of determining the hydrogen
permeability parameters of stratified materials is considered.
The model includes diffusion, invertible capture and
sorption/desorption processes on surface, which leads to
dynamical boundary conditions. For the concentration impulses
method, the equation of stationary oscillations of concentration
is obtained. Parametric identification scheme of the model is
proposed. Techniques of Fourier series and conjugate equations
