Abstract: Using the classical numerical methods for solving of hydrogen diffusion problem in the neighbourhood of small pore does not allow to calculate hydrogen concentration (for example, pressue of hydrogen). The numerical method which allows to obtain the values of concentration and flow of hydrogen into pore is developed. Precision of the numerical solution depends on the number of knots and does not depend on size of the pore. Technological thermal regimes are investigated.
