摘要
Under the dual pressure of energy consumption and environmental pollution, new energy generation and hydrogen energy have attracted much attention. Hydrogen fuel cell vehicle is the most widely used terminal application scenario of hydrogen energy. The on-board liquid hydrogen cylinder is widely regarded as an important type of fuel tank for fuel cell vehicles in the next stage due to its high density and lightweight. The safety and reliability of on-board liquid hydrogen cylinder are the key problems at present. In view of the complex operating environment and high accident hazards of hydrogen fuel cell vehicles, the essential safety, high efficiency and energy saving of vehicles are very important. However, the design method of on-board liquid hydrogen cylinders is not perfect, and there are failure risks such as brittle material breakage, fatigue failure and vacuum loss. In this paper, the key design links of vehicle-mounted hydrogen storage bottles are discussed from the aspects of material selection, model selection, design and testing. The historical development and related research progress are reviewed on ductile brittle transition of liquid hydrogen cylinder material, and performances of vehicle-mounted liquid hydrogen cylinders, including static and dynamic analysis, using process and the fatigue life, thermal insulation performance after loss of vacuum, pressurization design and boosting heat transfer. The research trend of on-board liquid hydrogen cylinder is forecasted. Finally, the key technology of on-board liquid hydrogen cylinder design is summarized and prospected. ? 2023 Chemical Industry Press.
