Abstract A 3D numerical heat-and-mass transfer model was used for the comparison of H<inf>2</inf> uptake performances of powdered cylindrical MH beds comprising MmNi<inf>4.6</inf>Al<inf>0.4</inf> hydrogen storage material. The considered options of heat exchange between the MH and a heat transfer fluid included internal cooling using straight (I) or helically coiled (II) tubing, as well as external cooling of the MH bed without (III) and with (IV) transversal fins. The dynamic performances of these layouts were compared based on the numerical simulation. The effect of heat transfer coefficient was also analysed. © 2015 Elsevier B.V.
