Notes:

No possibility at this time to estimate aircraft production cost at an assumed up-scaled production level.

1. Durability of the fuel cell system until 10% power degradation.

2. Percent amount of time that the aircraft is able to operate versus the overall time that it is intended to operate.

3. Actual cost of the fuel cell system - excluding overheads and profits for mass production volumes.

  • Ram air turbine - emergency system replacement (RAT) (15-50 kW)
  • Propulsion (40 kW)
  • Cabin Loads - APU (5-20 kW)

4. FC Stack & Power converter.
