This project aims to design and develop a hybrid submarine that is capable of generating its own fuel, breathable air, and drinkable water from the seawater surrounding it. The submarine will be powered by a combination of conventional diesel propulsion and hydrogen combustion, which will provide the necessary energy to power the onboard systems and propulsion. The submarine will be equipped with a desalination system that will convert seawater into drinkable water using reverse osmosis and electrolysis technology. Additionally, the submarine will have an air purification system that will extract oxygen from the seawater and remove any impurities, providing the submarine with breathable air. The submarine will also be equipped with a fuel generation system that will use seawater to produce hydrogen fuel. This will be achieved through a process called electrolysis, where seawater is split into hydrogen and oxygen using an electric current. The hydrogen will then be stored in onboard tanks and used to power the secondary hydrogen engine, providing the submarine with a sustainable and renewable energy source. The project will also focus on the optimization of the submarine's design and systems to ensure maximum efficiency and minimize the impact on the environment. This will include the use of advanced materials, such as composites, to reduce weight and increase the submarine's stealth capabilities. Overall, this project aims to develop a hybrid submarine that is self-sufficient and able to operate in a sustainable and environmentally friendly manner. This technology has the potential to revolutionize the way submarines are designed and operated, making them more efficient and reducing their reliance on finite resources. This paper gives an overview of the systems onboard to operate the fuel cell, namely, hydrogen and oxygen storage, as well as the safety aspects related to fuel cell operation inside the closed atmosphere and sustainability.
