Fuel-cell vehicles are suddenly getting a lot of attention. This past week, Toyota (NYSE:TM), Honda (NYSE:HMC), and Hyundai (NASDAQOTH:HYMTF) all presented show vehicles powered by hydrogen fuel cells -- and all three said that similar models will soon go into production.

Those three are just the bow wave of a slew of new hydrogen cars that are expected to hit the U.S. market in the coming years. In this video, Fool contributor John Rosevear explains why fuel-cell cars are suddenly in the limelight -- and when you'll start seeing them on American roads.
