Radically New Hydrogen Fuel Cell Technology to Transform Aviation, Backed by USAF - autoevolution

"This innovative fuel cell system was proven to deliver up to 2,000 watts per kilogram of specific power (three times more than liquid-cooled hydrogen), and an energy density of up to 1,500 watt-hours per kilogram, for a major increase in range."

That's about the same power density (specific power) as the best high-energy batteries and at least 6 times the energy density (specific energy). Very impressive if true.
