I found this article at Space.com (see link in related links) I hope is helps.
"Built by Russian engineers, the Elektron device aboard the space station uses electrolysis to separate water into hydrogen, which is dumped overboard, and oxygen. The 1,500-pound (680-kilogram) OGS rack works in much the same way, and will be able to provide 12 pounds of breathable oxygen daily under normal operations, NASA officials said."

Why do scientists use full scale mockups of space vehicles and the International Space Station before a real mission?

Why did they make the international space station?
They made the international space station, because astronauts in earth orbit, can do experiments and learn stuff, they could not do on the planet. They can study outer space more easily, when there are no clouds blocking the view. They can look down at the earth and study pollution and weather much better from outer space. A space station has more room than the 3rd stage of a Saturn V moon rocket that was used for the Skylab space station in 1973. Having people in orbit offers many opportunities that being earth bound does not.
