Flight Test Results for a Fuel Cell Unmanned Aerial Vehicle

Fuel cell -powered aircraft are an emerging and impo rta nt application of fuel cell and advanced aircraft technologies. This paper presents and analyzes test results for a fuel cell powered unmanned aerial vehicle. The aircraft under analysis is a fully functional technology demonstrator that uses a polymer ele ctrolyte fuel cell system fueled by compressed hydrogen . The tested performance of the fuel cell system, propulsion system and aircraft is critically evaluated using data from flight and laboratory testing.
