Design of Charging Station System for Underwater High Energy Density Oxyhydrogen Fuel Cell

Based on the physical structure of the 20-foot container, this paper carries out the theoretical analysis of underwater charging station system about energy allocation of oxyhydrogen fuel cell and lithium batteries, and carries out the analysis of the equipment and components that have a great impact on the total weight of the charging station system, and summarizes the design principles to improve the energy density of the charging station system. The energy density of the underwater charging station is comprehensively improved in the aspects of technical design, material selection, structure and technology. The maximum structural configuration of hydrogen and oxygen gas storage vessel is carried out. The oxyhydrogen fuel cell and its auxiliary system realize the compact and lightweight design. The standard pressure chamber also achieves a lightweight design under the condition of 300m underwater pressure operation. The design and calculation results show that the charging station has high energy density, simple engineering implementation and can meet the requirements of underwater closed environment operation.
