The performance simulation of air-cooled hydrogen storage device with plate fins

摘要

This paper presents the heat and mass transfer performance of an air-cooled, multi-tube hydrogen storage device with plate fins and LaNi₅ as a hydriding alloy. The effects of number of tube rows, bed thickness and ratio of pitch distance to tube diameter (s/d) on the sorption performance of the device are reported. The influence of operating parameters such as air velocity and temperature on hydrogen sorption is also presented with emphasis on charging time and total system weight.
