Boeing Working on Fuel Cell Aircraft

"Boeing is working with development partners on a fuel cell-based small aircraft. It seems like a logical use of the technology. Now if they can come up with a quiet, personal-sized VTOL craft a la Paul Moller's Skycar (which is anything but quiet), we'll really have something." From the article "A Boeing research director was quoted as saying, "While Boeing does not envision that fuel cells will provide primary power for future commercial passenger airplanes, demonstrations like this help pave the way for potentially using this technology in small manned and unmanned air vehicles."

Reliability?

[mcrbids]

One of the biggest problems with smaller aircraft is reliability. Simply put, piston engines are not as reliable as jet engines. They must be rebuilt every 2,000 hours of flight under the best circumstances. And, with smaller planes at slower speeds, jets just don't make sense.

Turboprop engines are a good middle ground for mid-sized planes starting at the 12-seat size or so, but are very expensive for the smallest aircraft. (2 and 4 seaters)

Electric motors, other the other hand, can be incredibly reliable. If designed for it, they have just a single moving part, and can run continuously, 24x7x365 for many years without issues. This kind of reliability in a small plane would be just incredible!
