Abstract: With the increasing awareness of environmental protection, hydrogen fuel cell vehicles have attracted much attention because of their advantages such as high energy efficiency, no pollution and low noise. However, as the core component of fuel cell vehicles, the limitations of hydrogen storage system of hydrogen storage system, such as small hydrogen storage quality, short range, self-significant and high cost, restrict the development of fuel cell commercial vehicles. This paper focuses on the application of different hydrogen storage methods in fuel cell commercial vehicles, and conducts in-depth research and analysis of the integration, lightweight, large volume, and localization of high-pressure gas hydrogen storage system. Finally, the future development and research direction of the on-board hydrogen supply system are discussed.
