Abstract
In order to make efficient hydrogen storage utilization as a fuel in fuel cell plant, there is need
for its effective storage. Previous studies on hydrogen storage considered the hydrogen adsorption/
desorption in radial direction only which is one dimensional approach in this project, two dimensional
computational model is implemented in CFD software to simulate the diffusion and heating
of hydrogen in both radial and axial directions. The model consists of a system of partial differential
equation (PDE) describing two-dimensional heat and mass transfer of hydrogen in porous matrix.
Mathematical model was developed to simulate heat and mass transfer in a packed bed reactor with
metal hydride as a material for hydrogen absorption and desorption. Importance of bed porosity
radial distribution and correct equation for effective thermal conductivity is discussed.
