Hi,

here is some IAI and Boeing fuel cell-powered aircraft and UAV.

AFAIK it only makes sense for a solar craft for storing the energy for the night. NASA was prototyping this when their huge solar powered flying wing crashed.

Fuel cells are still very heavy compared to internal combustion engines, though a hydrogen + fuel cell system is lighter than batteries already.
 
Hi,

the IAI fuel cell-powered UAVs.

The article mentioned that a demonstrator was scheduled to fly by the end of 2005.
Somebody knows if that flight was indeed performed or has more details on the HA-310 and HA-315?

Thanks in advance
 
Hi,

a more info about Boeing Fuel Cell project.

Something that seems like it could be relevant:
 
We identify an optimal flow regime range, broadly applicable to other liquid-fed fuel cells, in terms of the standard dimensionless Reynolds number (Re) and the Damkohler number (Da). DBFCs fulfilling these criteria provide a 2.4 times higher power density at 1.5 V compared to state-of-the-art polymer electrolyte membrane fuel cells (PEMFCs) that typically operate at 0.75 V. The high peak power density of 890 mW cm−2 at 1.1 V may offer a pathway to reduce fuel cell stack size for propulsion applications.
