The temperature of the compressed air is usually greater than 250 °C at a pressure of 10 bar. Adiabatic compressed air energy storage without thermal energy storage tends to have lower storage pressure, hence the reduced energy density compared to that of thermal energy storage [75]. The input energy for adiabatic CAES
Introduction. Fuel cell vehicles (FCVs) are considered a potential solution for the reduction of emission for transportation by substituting fossil fuels with green hydrogen produced from renewable energy [1, 2].However, the high cost of hydrogen fuel is still hindering the large scale application of FCVs [3] order to be as competitive as fossil
This paper aims to systematically review these behaviors by utilizing the ''mechanical origins – structural changes – electrochemical changes – performance'' logic.

During the fast-filling of a high-pressure hydrogen tank, the temperature of hydrogen would rise significantly and may lead to failure of the tank. In addition, the temperature rise also reduces hydrogen density in the tank, which causes mass decrement into the tank. Therefore, it is of practical significance to study the temperature rise and
