Fuel Cell / Energy Expert needed for Power Problem (endurance)

Without saying to much about this project, we need someone to find a better solution to power 4 motors much longer than our current 11.1V 20Amp LiPO RC battery is capable of doing.

Weight is a big factor, as we need to keep the weight as low as possible, and we could potentially have to work at .5 miles up in the air, possibly more.

We think Fuel Cells are the way to go here, but are willing to look at any and all solution(s) that will work.

We need to maintain 11.1V 20Amps for at least 3 hours.
Currently, the LiPO battery we use is giving us 35 minutes, and we could add a second and get to an hour, but can do no better with LiPO, and they work better for us than any other conventional battery type we have used.

If this job is of any interest to you, please let us know and we will gladly send you an NDA and discuss payment/deliverables/details, etc...

Thank you for looking,

Trevor
