“…Another similar study has also shown the effectiveness of upward injectors. [26] This study infers that the upward injectors may have two benefits: one is to prevent the thermal fields in FCEV tanks from being unevenly distributed, and the other one is to increase the hydrogen's heat convective transfer coefficients to effectively transfer heat from the hydrogen gas to the liners.…”

Herein, the temperature of the inner tank walls, or plastic liners, of composite pressure tanks in fuel cell electric vehicles during fueling using three‐dimensional computational fluid dynamics (CFD) models is evaluated. The liner materials are limited to 85.0 °C to prevent thermal stress causing material failure that would result in a hydrogen leak. Therefore, the temperature of hydrogen gas must be limited to below 85.0 °C during the fueling process as dictated by the current fueling protocol. However, there are limited experimental or simulation data confirming that the temperature changes do not exceed the threshold. Herein, the liner temperatures with CFD tank models for two sizes of type IV tanks representative of the upper and lower system bounds that are close to the SAE J2601 fueling protocol (36.0 and 244.0 L) are evaluated. First, each model's reliability is validated with experimental data and then analyzed, and the data are used to evaluate the maximum hydrogen and liner temperatures under real‐world fueling conditions. The evaluation shows that the maximum liner surface temperature of each tank model is at least 7 °C lower than that of the hydrogen. Additionally, there is at least 12 °C difference found between the upper limit and actual liner temperatures.

“…To address temperature rise effects, Zhang et al [ 89 ] suggested measures such as pre-cooling of hydrogen, staged filling, controlling filling rate, and selecting suitable lining materials for hydrogen storage tanks. Wu et al [ 90 ] introduced time-delayed filling strategies that significantly reduced filling time under normal conditions. This approach saved 62 % of the time compared to constant mass flow filling.…”

“…In addition, some numerical models have been built to research and optimize the thermodynamic effects on the hydrogen tank during the fast-filling process [4][5][6][7][8][9][10][11]. A hydrogen fueling station thermodynamic model was introduced to simulate the hydrogen temperature, hydrogen pressure, and mass flow rate at any position during the charging process [4].…”

A reasonable inflating strategy must be developed for filling an onboard hydrogen storage tank with hydrogen gas. The inflow hydrogen temperature has always been a constant value in filling cases. However, in our opinion, the optimal inflow hydrogen temperature is not supposed to be a fixed value but a value that constantly changes and adjusts with filling time, i.e., the inflow hydrogen temperature is a function of the filling time. How to determine this functional relationship is a critical problem to be addressed. Herein, an approach is introduced. A dual-zone model is presented to research the thermal effect during the process of charging hydrogen storage tanks. Based on the numerical results of the dual-zone model, the charging process was divided into three stages, allowing us to obtain data for 1331 filling cases. Then, a back propagation (BP) neural network model was built to analyze the data, and the implicit relationship between the inflow hydrogen temperatures and maximum hydrogen temperature pressure could be deduced. With this implicit relationship, the critical values of the inflow hydrogen temperatures can be obtained from the critical situation. Suppose the inflow hydrogen temperatures in a practical case are higher than the critical values. In that case, the highest hydrogen temperature in the tank will exceed the limited safety value of 358 K. In contrast, if the inflow hydrogen temperatures are lower than the critical values, then more energy will be needed to precool the inlet hydrogen temperature. Thus, theoretically, the critical inflow hydrogen temperatures should be at their optimal values.
