Abstract
In order to reduce the time to charge a MH-tank, the heat exchange performance of a tank has to be improved. In this study, several MH-tanks with an effective storage capacity of 1.25Nm^3 were manufactured in different structures. Through the charging tests and the heat transfer simulation, influences of structure on the temperature distribution inside the tank and on the charging time were investigated. Based on the data, the structure of the MH-tank with an actual capacity as a storage device for a FCV of 31.25Nm^3 was optimized. The 80% of an effective storage capacity could be charged within 10min.
