The State Fuel Cell and Hydrogen Policy and Demonstration Database is a partnership between FuelCells.org and the DOE's Hydrogen Project. There is also a separate chart for upcoming hydrogen fueling stations, the Hydrogen Fueling Station Chart. Stationary fuel cells are listed in a different area, the Worldwide Stationary Fuel Cell Installation Database.
I poked around the main database a bit, searching for hydrogen vehicle items and found 11 hydrogen fuel cell vehicle projects here in Michigan, part of 187 in the entire country. The DOE says this database is a work in progress, so if you find information missing or that is incorrect, let them know.
