Abstract

The promotion of hydrogen fuel cell electric vehicles (HFCEVs) is of great significance for reducing carbon emissions and strengthening environmental protection effects. However, the temperature drop occurred during discharging, becomes a key safety hazard for the reliable operation of HFCEVs. In this study, a type IV hydrogen storage tank with a pressure of 70 MPa is adopted to research the thermal behavior during discharging. The discharge expansion of high-pressure vapor hydrogen, the turbulent heat transfer at high velocity, the thermal conductivity through the tank structure layers and the convective heat exchange between the storage tank and the ambient, are considered in model construction. A one-dimensional unsteady heat... (More)

The promotion of hydrogen fuel cell electric vehicles (HFCEVs) is of great significance for reducing carbon emissions and strengthening environmental protection effects. However, the temperature drop occurred during discharging, becomes a key safety hazard for the reliable operation of HFCEVs. In this study, a type IV hydrogen storage tank with a pressure of 70 MPa is adopted to research the thermal behavior during discharging. The discharge expansion of high-pressure vapor hydrogen, the turbulent heat transfer at high velocity, the thermal conductivity through the tank structure layers and the convective heat exchange between the storage tank and the ambient, are considered in model construction. A one-dimensional unsteady heat transfer theoretical model is proposed and the detailed derivation process is presented. The temperatures of hydrogen gas within the storage tank, inner liner and outer wall of the storage tank, are obtained by iterative solution. Two discharging experiments are selected to validate the proposed theoretical model, and the temperature deviations between the simulated results and experiment data are limited within ±2 %. The impacts of the discharging parameters, initial settings, dimensions and thermal properties of the tank liner and laminate, on the discharging of HFCEV storage tanks are investigated. The results indicate that a small discharge rate and a low ambient temperature will cause a large temperature drop inside the tank. A low initial tank pressure leads to an increasing trend in discharge temperature. Increasing the thickness of the tank liner and laminate enhances thermal storage capacity of material layers, thereby alleviating the temperature drop within the storage tank. Furthermore, increasing the tank length improves temperature control and benefits long-term operation of HFCEVs. This work can deepen researchers’ understanding of the temperature drop of on-board hydrogen storage tanks during discharging, and provide technical references for the optimal operation design of HFCEVs.
