I guess since the king is on h5 to begin with, White will never allow you to get it behind the pawn and the rook. Weird endgame...
I should check what happens when you have a g, f and e pawn. Maybe the h pawn is some kind of exception.
Edit: Checked it and it seems g and h pawns draw - with an h pawn it's significantly easier than with a g pawn. With an f or e pawn you are lost. The idea is to bring the king toward the pawn from behind - and this is achieved via series of zugzwangs. (for g and h pawns the queen does not have enough room to maneuver and thus cannot dislodge a king that defends stubbornly behind the rook and the pawn)
