Abstract:

The kinetics of hydrogen absorption in getter materials is studied. The dissociation of hydrogen molecules on the surface, penetration of hydrogen atoms into the material and bulk diffusion are taken into account. This paper extended the investigation on a wall (1D Cartesian case) performed by Liu et al. to a hollow cylinder more closed to technological application. The resolution of the equation system is solved in an analytical way (Bessel and Euler functions included) or by finite difference methods (Explicit and Implicit schemes are described). For a given time period, the filling rate of hydrogen absorbed in the container can be estimated.
