Attained Temperature During Gas Fuelling and Defueling Cycles of Compressed Hydrogen Tanks for FCV

In this study, we conducted hydrogen gas filling and discharging cycling tests to examine the thermal behaviour in hydrogen storage tanks under actual use conditions. As a result, it was confirmed that the gas temperature in the tank varied depending on the initial test conditions such as the ambient temperature of the tank and the filling gas temperature, and that the gas temperature tended to stabilize after several gas filling and discharging cycles.
