Fueling Cars with Water: Korean Research Team Develops Tech to Mass Produce Hydrogen

7. I trust that your math may be better than mine but it looks resonable

If I could purchase a hydrogen powered
vehicle at an affordable cost and be able to "fill it up" for the equivalent of ~$5/gallon, I'd be driving one.

Some quick data on the Electric Nissan Leaf

"
The pure electric Nissan Leaf costs just 3.5 cents a mile based on the national average of 11 cents/kWh of electricity. That’s less than half of what it costs to drive the most fuel-efficient four-door car we’ve tested, the Toyota Prius. (This calculation doesn’t include other costs such as maintenance or depreciation. But maintenance on an electric car is theoretically miniscule compared with gasoline cars. And depreciation is unknown for such a new technology.)"
