Furthermore, we have developed a new numerical prediction method related to the diffusion flow characteristics and combustion limits of hydrogen leaking due to crack propagation failure of high-pressure tank bulkheads. Practical Application We contribute to the design of hydrogen storage containers for various types of transportation equipment and the development of safety guidelines and risk management for hydrogen station configurations.
