摘要：Oxygen is one of the chemical elements in its atomic number is 8. It is a bio-element and it is found everywhere on the universe from each to air. Oxygen molecule is unstable the thermodynamically and it is produced through photo synthesis of nonaerobic bacteria and in the plants. Oxygen in standard pressure and heat is in the form of a gas that consists of two atoms of oxygen (O2). Oxygen is an important element of the air that is produced through photosynthesis of plants and it is necessary for all living beings. The aim of present research is designing a system for producing oxygen from sea water. In this design the water in the container is analyzed to photosynthesis Oxygen and hydrogen by electricity and then it is separated by a special machine and each of the gases are entered into breathing capsule and a balloon by internal and external sucking. Results of this research will help divers to remove their problems
