I have a friend who has been working on Hydrogen and fuel cells since 1999. He told me in 2001 that it was never going to happen for cars and that fuel cells just are not going to pay off except for a few instances that aren't really clear.

2016 he says the same thing. Fuel cells will never be the fuel for cars and no clear viable application. The issue is that you can't just go with hydrogen into a magical filter and split the hydrogen atoms and get energy without it costing multiple more then gas or electric.
