Abstrakt: The problem of hydrogen diffusion in a metal with pores was formulated. Pores are the traps of hydrogen absorption. Traps were considered to be point-like and distributed uniformly over the entire volume of the metal. Solutions to the problem of diffusion in a defective body were obtained. In particular, expressions for determining the concentration of both diffusible and trapped hydrogen for the plate were obtained. The ratio for determining the amount of hydrogen sorbed by a defective plate at an arbitrary moment of time during the plate hydrogen charging was also obtained. The amount of hydrogen sorbed by a defect-free plate and a plate with uniformly distributed traps was compared. A 2–3 time excess of hydrogen content in the defective plate compared to the defect-free plate was established. [ABSTRACT FROM AUTHOR]
