Abstract :In this study, hydrogen absorption in a metal-hydride bed is numerically investigated. The mathematical model considers the heat and mass transfer and thechemical reaction that take place during the absorption. The hydride bed heats up due to the exothermic reaction. Numerical results show that hydrogen absorption is completed faster near the cooled wall, while it takes longer at the center. Hydriding processes are investigated with the temperature histories, H/M ratio and temperature distributions at several locations in the tank. Th estimated H/M ratio is found to agree satisfactorily with the experimental data in the literature.
