ON THE OPTIMIZATION OF CONVECTIVE HYDROGEN STORAGE BED MODEL USING LANI5H6 OR FETIH1.6

This paper is part of an integrated calculation scheme in the context of hydrogen energy systems. The work aims at the development of an optimized hydrogen storage bed based on the convective bed model and using LaNi5H6 or FeTiH1.6 metal hydride as the hydrogen charging-discharging medium. In this paper, the main factors affecting the rate of hydrogen release have been studied and found to be ordered as follows according to their potential impact on the hydrogen discharging rate: inlet hydrogen temperature, bed pressure, inlet gas mass flow rate, bed length and bed void fraction.
