The increase in temperature of a gas has been measured during filling at a high pressure. Heat transfer between the compressed gas and the tank affects the strength of CFRP gas tanks which should be operated below 80℃. The experimental conditions are that filling gas is Hydrogen at 35MPa and at a filling mass flow rate of 50-180g/min. The temperatures are measured either vertically or horizontally at five positions in the tank. The characteristic of the gas temperature increase during filling and after filling are categorized into 4 regions. Coefficient of natural convective heat transfer is also given for different filling rates and for Hydrogen and Nitrogen.
