Submarines typically generate oxygen through a process called electrolysis.
In this process, electricity is used to split water molecules into hydrogen and oxygen.
The hydrogen is then vented overboard, while the oxygen is collected and stored for use by the crew.
Some submarines also have systems that can scrub carbon dioxide from the air and release pure oxygen, which can be mixed with the oxygen generated by electrolysis to create breathable air.
Additionally, some submarines have the ability to surface and take in fresh air when necessary.
Overall, the method by which a submarine generates oxygen depends on the specific design and technology of the vessel.
