When the technical problems are resolved. And not the least of which is - where do you get the energy to make the hydrogen?

When they are cheap enough, can travel far enough, and people can get fuel conveniently.
This may be never. Hydrogen is perfectly clean to burn or to generate electricity in a fuel cell, but there are some impracticalities that do not have easy answers.
A gasoline car that gets 25mpg can go about 300 miles on 12 gallons of fuel (About $40). You can fill up in less than 5 minutes just about anywhere.
No one is going to jump to an exotic technology just because it is clean. It has to meet the other needs of cost, availability and convenience. Many more prosaic technologies have a better chance of doing that in the near term (Hybrids, battery electrics, clean diesels). While not as clean as hydrogen, they all reduce the amount of fuel burned and therefore are cleaner than what folks are doing now with 15mpg gasoline vehicles.
