Exactltly, more energy than the resultant hydrogen will yield in a fuel cell.

Actually, the point of hydrogen fuel cell cars is that you can control the pollution of 1000 nuclear or coal burning power plants making the hydrogen, better than you can 100 million individual vehicles. Also, our reliance on foriegn sources of petroleum could be curtailed with the implimentation of hydrogen fuel cell cars. However, right now the cars are very expensive and require precious metals such as platinum, acting as catalysts in the fuel cells, that until we find new catalysts the cost will never come down.

There is also the building around 1000 new nuclear power plants in 25 years to produce all of the hydrogen required for this "hydrogen economy".

It might happen in 50 years, might not. I am not a betting man, so I will stay away from placing odds.
