As far as where do you get it. It is probably a complex/costly process, but distilled water is a readily available source of hydrogen (h2o). While hydrogen might not be as combustable as gasoline, it is still very volitaile, Hindenberg anyone? I think eventually we will see some kind of electric/hydrogen hybrids, where the car has an electric hydrogen condenser, so all you have to do is add water to the tank, then the electric portion of the car will separate the hydrogen out. The trick then would be to either manage to keep the ammount of fuel grade hydrogen low, or facilitate a storage method to lower the volatility of it. In a wreck between a pair of hydrogen cars there is a pretty good chance of an explosion I would think, however I haven't taken chemistry, so perhaps someone with more technical/chemical knowledge can either debunk my idea or lend some credibility to it.
