You can get a few bubbles with a battery, but to fill the rocket with oxygen you need a huge solar farm or something similar to power the electrolisis plant. Oxygen atoms are easy to find, sand and rust (and water) have a lot of them. The problem is isolating them to produce molecular oxygen that can be used to burn the fuel.

There are already semi-serious proposals to solve the Earth's energy problems with space based solar collectors. Of course they would have to a lot bigger further out. Perhaps Jupiter's flux tubes could be tapped.
