The Fuel-Cell Powered DynAero Lafayette III experimental two-seater aircraft
  The world's first fuel-cell powered aeroplane crossed the boundary from fiction to potential reality due to advances by The Foundation for Advancing Science and Technology Education also known as FASTec.  Using a Dynaero Lafayette 3 as the vehicle they plan to gradually phase the power of the plane from normal combustion to fuel-cell energy.  First the plane will be adapted to electricity using lithium ion batteries, the same kind used in small electric cars such as the Nissan Altra EV, with test flights in 2002.
  This will be followed by a conversion to  battery power enhanced with a fuel-cell and lastly to the plane's complete reliance on hydrogen fuel-cell energy.
