Abstract
The diffussion controlling H2 desorption kinetics was found by the measurement of desorption rate of LaNi5H6. According to this result, two methods of analysing the activation energy were examined, one for diffusivity and another for temperature dependence on the desorption rate. From data obtained, the activation energy for diffusion of H was calculated. The activation energies obtained from two different analitic methods were compared with each other.
