[0002] After years of development, traditional fuel-powered aviation technology has become highly mature. From optimizing engine performance to designing and implementing aircraft fuel tank systems, these technologies have reached near-perfect perfection. However, with the increasing scarcity of global energy resources and the rapid development of a low-carbon economy, the aviation sector, a fuel-intensive industry, faces an urgent need for transformation. To adapt to global sustainable development trends, the aviation industry must explore and adopt more environmentally friendly and efficient energy solutions to reduce its reliance on traditional fossil fuels and effectively control carbon emissions.

[0003] Fuel cell technology, as a clean and efficient energy solution, has garnered widespread attention. Fuel cell aircraft, an emerging aviation technology, boast advantages such as zero emissions, low noise, and high energy efficiency, and are therefore becoming a key direction for future aviation development. Hydrogen, the primary energy carrier for fuel cells, poses a critical challenge in the safe and efficient storage and transportation of fuel cell aircraft.

[0004] At present, the installation and fixation of hydrogen storage tanks in fuel cell aircraft usually adopt traditional means such as bolts and clips. This type of fixing method has problems such as cumbersome installation and removal process and insufficient stability. Especially during aircraft operation, frequent replacement of hydrogen storage tanks requires improving operational efficiency and reducing downtime, while ensuring the reliable fixation and safety of hydrogen storage tanks in highly dynamic environments. Existing technologies cannot effectively solve the problems of rapid installation, removal and stability of hydrogen storage tanks, which affects the operating efficiency and safety of fuel cell aircraft. Finding a method that can quickly install and remove aircraft hydrogen storage tanks while ensuring their safety has become a key challenge in the current fuel cell aircraft field.
