Diffusion of hydrogen into a bulk of molybdenite crystal that is exposed to hydrogen gas is studied by measurement of gas emitted from a bulk crystal during cleavage experiment. The cleavage experiment is performed to observe the change of hydrogen concentration in the bulk by the sample heating. The experiment shows that amount of emitted hydrogen molecules and water reduces but emitted hydrogen atoms do not reduce much when the molybdenite crystal heated at 300°C is cooled to room temperature. This suggests that hydrogen molecule adsorbed dissociatively on the surface, and then the hydrogen atoms diffuse into the molybdenite crystal.
