At UAF we fly UAV's for many different research projects. A lot of the time our flight times are small because of the battery. We are looking for ways to fly longer times and we know that fuel cells are the way to go! Some of our sensors that we fly are around 500kg. But we need to fly longer. Somethings I think we are work on is how does a fuel cell handle in extreme cold climates. I have access to some of the coldest places in Alaska with temperatures down in the -50F. We think that coming together with other Universities is way more beneficial then giving some big name company thousands of dollars. You gain knowledge along with it. I think the biggest question here is what progress have you made and is it something that could help us out a lot.
I hope that I have answered your question. As I believe it will be really great work and very beneficial in the future to tell people about this type of technology flying in UAV's today.
I have been following your works on the hydrogen cell and am about ready to go into that subject. Are there any 'Tips' that you can share and also do you have a schematic wiring diagram for your 100W system? Thank you.
