Fuel Cell-powered UAV Flies Continuously for Seven Hours

The ProCore UAV propulsion system is a fuel cell that couples stack technology that can achieve 1,000W/kg (454W/lb) power output with a chemical hydride for storing its hydrogen fuel.

Aerovironment's Puma unmanned air vehicle has flown continuously for over 7h using the US fuell cell company Protonex's ProCore UAV system.

The US Air Force Research Laboratory UAV development project already achieved a 5h endurance in June last year with a Protonex powered Puma, which has a wingspan of 2.59m (8.5ft), is hand-launched, has a rechargeable battery powered flight time of 2.5h, can fly autonomously and uses satellite navigation. It provides aerial observation at line-of-sight ranges up to 10km (5.4nm).
