Hi,

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

Boeing working on Fuel Cell Airplane

March 28, 2007 With all the effort we are witnessing in developing environmentally progressive technologies for automotive applications, it’s great to see that Boeing researchers and industry partners throughout Europe are planning to conduct experimental flight tests this year of a manned airplane…

Hi,

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

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.
