The fuel is Hydrogen, the most abundant element in the universe. You can't get any more common than that

Most fusion reactor designs use rare materials since hydrogen doesn't fuse on it's own. It needs a catalyst to begin the process. We have no method of controlling a sustained fusion reaction at the moment, so the more realistic designs generally just fuse fuel pellets and capture the energy released, using a portion of it to fuse the next pellet.
