Summary: The type IV hydrogen storage tank with a polymer liner shows promise as a storage solution for FCEVs. The polymer liner reduces weight and increases storage density. However, hydrogen tends to permeate through the liner, especially at high pressure. Comprehensive understanding of decompression damage is crucial for developing suitable liner materials and commercializing the type IV hydrogen storage tank. This study discusses the mechanism of decompression damage, including characterizations, evaluations, influential factors, and prediction. Future research directions for further investigating and optimizing tanks are proposed.

Summary: Fuel-cell vehicles (FCVs) are a cutting-edge and zero-emission car technology that can be promoted by establishing efficient hydrogen refueling stations (HRSs). This study records and analyzes the quantity of FCVs and HRSs in China to understand past and future scenarios, focusing on HRS location and FCV refueling distance. After 2018, there has been a decrease in the FCV/HRS ratio due to the rapid growth of HRSs, indicating an improved refueling experience and reduced refueling distance. The Roadmap of China aims to build 5000 HRSs by 2035. By concentrating the projected HRSs in cities with diverse population sizes, the refueling distance in 2035 could be as short as 5 km, which aligns with consumer expectations for fossil fuel-powered vehicles. Moreover, by centralizing the limited HRSs in cities with over 5 million people, the refueling distance may be further reduced to 3 km. This work provides a feasible and applicable strategy to prioritize the development of necessary HRS networks in densely populated city regions to promote FCV adoption.

Summary: Hydrogen has garnered significant attention as a clean energy source due to its high thermal conversion efficiency, recyclability, and non-polluting properties. The increasing number of hydrogen fuel cell vehicles and refueling stations globally underscores their research prominence. However, the rapid increase in internal temperature caused by high-pressure hydrogen filling poses a major challenge. This review systematically elucidates the temperature rise principle, summarizes the impact of refueling parameters on tank state, and proposes mitigation measures and solutions to limit or mitigate temperature rise effects, such as pre-cooling hydrogen, reducing initial hydrogen content, and maintaining low ambient and initial tank temperatures. Furthermore, safe refueling strategies and methods are presented. The comprehensive study in this paper refines the crucial relationship between refueling parameters and tank temperature rise, providing valuable insights for advancing new refueling strategies and hydrogen fuel cell vehicles.

Summary: This study investigates the effects of charge/discharge cycles on the performance of a commercial automotive metal hydride hydrogen storage system in a fuel cell electric vehicle. A mathematical model is proposed based on uncertain physical parameters, and the variation of these parameters allows for an assessment of tank degradation. The results show that tank degradation can be predicted by developing laws of variation of these parameters as a function of the real conditions of FCEV use.

Summary: New energy vehicles such as electric vehicles (EVs) and hydrogen fuel cell vehicles (HFCVs) are being developed to replace internal combustion engine vehicles and fossil oil. A comparative analysis reveals that electric passenger vehicles have more advantages in terms of economy, safety, and environmental impact, while hydrogen fuel cell passenger vehicles face significant obstacles. However, hydrogen fuel cell commercial vehicles have unique application scenarios. The dislocation and complementarity principle should be considered when implementing EVs and HFCVs in different scenarios.

Summary: This work provides essential insight into the evaporation process of a thin film on an extended surface. The study reveals that introducing nanoparticles can enhance heat transfer in the thin film, but electrostatic interactions can increase the total disjoining pressure and reduce the capillary pressure. Neglecting electrostatic interactions can lead to an exaggeration of the thickness increment and an underestimation of heat transfer. Therefore, electrostatic interactions cannot be overlooked in studying the evaporating nanofluid meniscus of a polar liquid.
