When we fooled around making hydrogen and oxygen from water in Chemistry class, the hydrogen would ignite very readily and there was always a bit of water in the test tube. I don"t know if it was all from the hydrogen combining with oxygen to form water, or if some of it was from water vapor.
Maybe water vapor is the problem, but something will float in water or air by weighing less than the water or air it displaces. My guess is that there is not enough hydrogen in the balloon to weigh less than the air a balloon+hydrogen of that size displaces. It might work to fill the balloon with more hydrogen. And I would guess that there is some way to remove the water vapor from the hydrogen.
Hydrogen is notoriously difficult to contain. They had a terrible time containing the hydrogen in the pressurized gas bags in the Hindenburg and other lighter than air craft of the day. Modern plastics might work better, but hydrogen will always be difficult to work with and very inflammable. I doubt that we ever see large craft lifted by hydrogen again, at least in commercial service.
Have fun with your balloons, but remember, the hydrogen will burn very rapidly and could be dangerous to you or others. Good luck!
