Researchers at the Korea Advanced Institute of Science and Technology recently demonstrated a fuel cell system that can power an RC plane for up to 5 hours on just 500 grams (17 ounces) of liquid hydrogen, and is expected to power a UAV variant of the plane for up to 10 hours when the autonomous pilot system in completed. KAIST hopes to use the tech in a future Korean military UAV, and, pending funding, expects to have a complete production-ready drone within two years. I wonder how a fuel cell will effect my Asus R2H battery life! hmmm
