We're looking at fuel cells for certain classes of UAVs, mostly smaller air vehicles like Shadow and Scan Eagle.
In addition to the advantages in endurance over combustion engines, fuel cells are much quieter. For small tactical UAVs, stealth is often achieved simply by dampening noise emissions.
I have a few projects with the Naval Research Lab. Cool stuff.
