description: In the work process of hydrogen diffusion simulated by program finite element method for studying of impact of different initial hydrogen distributions on TDS spectra. During the research following tasks were solved: 1. Analysis of existing works, concerning the hydrogen destruction, for reg-istration initial hydrogen concentration after hydrogen charging. 2. Analytical calculation of impact of different initial hydrogen distribu-tions on TDS spectrum. 3. Transfer to solving finite element method and comparing the results with analytical ones. 4. Finite element building TDS spectra for different initial hydrogen con-centrations for estimation their impact on desorption curves peaks. In the work finite element method of solution of the problem is offered, simulating hydrogen diffusion process in the sample and hydrogen desorption during the heating. The described model allows numerically build TDS spectra at different initial conditions of hydrogen charging. The given research could help correctly interpret peaks of TDS spectra, distinguish diffusion peaks from peaks, creating by hydrogen trap. It is necessary for correct analysis of TDS spectra, by which binding energy of hydrogen with structure of solid could be calculated.
