<p>The slow hydrogen absorption kinetics, primarily caused by significant exothermic effects and resulting temperature variations, restrict the practical application of metal hydride. This study presents both experimental and numerical investigations of the Ti₂₄Zr₁₃Cr₂₅Mn₃₂Fe₆-based bed. The necessary kinetics and thermodynamic parameters for the simulation model were determined, showing a high degree of agreement between the experimental measurements and the fitted results. A cylindrical test reactor was also developed to evaluate the hydrogenation behaviours of the metal hydride bed under various operational conditions, using 9 Kg of powder in the larger reactor. The absorption and desorption processes of the AB₂-type metal hydride were simulated within this reactor. In order to improve heat dissipation and decrease experimental duration, internal square fins and heat exchange tubes (1/4′′, SS 316) were integrated into the reactor (outer diameter 76 mm, SS 316). The temperature evolution curves obtained experimentally were found to align closely with the simulation results, validating the numerical model’s accuracy and supporting the optimization of future metal hydride tank designs. This study offers valuable insights into the application of numerical simulations in advanced hydrogen storage systems.</p>
