Hydrogen fuel cell vehicles in the future, near or far?

Hydrogen fuel cell driven cars are on the road today, like the Honda HCX(sorry if the letters are wrong) which are out in Japan. They have these on small islands in Japan where clean cars are all they use. these cars have their own fueling stations in these places. also, they emit water after combustion. so far, Honda is the only car manufacturer i've seen that has made a successful hydrogen fuel cell vehicle.

Hydrogen Fuel cell project is really a great success

But the cost of implementing still remains high

As a result the practicality of the vehicle is less

Researches are going on in this field. Future of Fuel Cell is bright , but have to wait for that distant future to see them frequently on road
