For more information about hydrogen fuel-cells read this Ottawa Citizen story.
It has a very canadian bias, but it also contains a lot of great information. For example, many people are stating that fuel-cells are free of emissions, but that is not true. The hydrogen has to come from somewhere, and the most abundant source is fossil fuels!
Depending on how the hydrogen is extracted, the CO2 emissions can be nearly as high as engines currently produce. An onboard gasoline converter, as mentioned in the story, produces 90% as much CO2 as a combustion engine.
