How Could Oxygen be Distributed Throughout a Space Station?

This might seem like a simple question, but oxygen is a gas, which probably would make it difficult to move, especially in a Space Station with no gravity. However, there is a fairly simple solution to this. Liquids are a lot more easy to move and manipulate then gasses. Liquid Oxygen is a Cryogenic Liquid, which means it has a boiling point at less then -130 degrees Fahrenheit. That's really cold, it would probably take a lot of effort to get equipment that could get that cold, but a simple solution is available. Outer Space is -454.75 degrees Fahrenheit. Astronauts could simply expose oxygen to Outer Space to turn the oxygen into liquids, and then using refrigerated tubes and pumps could circulate it throughout the station. I doubt the tubes and pumps would even have to be -130 degrees, just cold enough so that the liquid doesn't immediately turn back into a gas. The liquid could be pumped into a small tank in each room, where at room temperature it would turn back into a gas, ready to be breathed in. Some might be wondering where the oxygen would come from. Most of it would have to be shipped from Earth in tanks, but scientists also say that plants can be used to both eliminate carbon dioxide and produce oxygen. Any questions or arguments?
