Oxygen Generating System (OGS)

An Oxygen Generating System (OGS) is a device used to produce breathable oxygen, typically on spacecraft or submarines. It works by separating oxygen from other gases in the environment, often through a process called electrolysis, which uses electricity to split water into oxygen and hydrogen. The generated oxygen is then stored or supplied directly for crew respiration. The OGS ensures a continuous and reliable supply of oxygen, maintaining safe living conditions in environments isolated from the Earth's atmosphere. This system is vital for long-duration missions where resupply is not possible.
