Abstract:

Objectives The onboard hydrogen supply system serves as a core component of hydrogen fuel cell vehicles. How to achieve complete hydrogen gas recycling and improve hydrogen utilization efficiency have become one of the key bottlenecks limiting the development of hydrogen fuel cell vehicles. Therefore, an analysis of the current development status of onboard hydrogen supply systems is conducted. Methods This paper introduces the basic working principles of onboard hydrogen supply systems, and summarizes the structure, working principles, and development status of six types of hydrogen-recycling supply systems and two types of non-recycling supply systems. The advantages and disadvantages of different hydrogen supply system modes are compared. The technical status of key components in onboard hydrogen supply systems, such as hydrogen storage cylinders, hydrogen refueling modules, and combination valves is reviewed. Additionally, the development status of core valves such as pressure relief valves, overcurrent valves, and manual valves is analyzed. Finally, the development trends and research directions for onboard hydrogen supply systems are discussed. Conclusions The recycling mode of hydrogen supply systems is the main development direction for the future. Advanced information technologies, automatic control technologies, and intelligent decision-making algorithms will be gradually applied to onboard hydrogen supply systems. The components of onboard hydrogen supply systems will gradually evolve towards lightweight, high reliability, low cost, standardization, and modularization.
