Innovative Hydrogen Storage Tank for Flying Fuel Cell Power System

Abstract

More and more often aerospace designers are considering hydrogen PEM (Proton Exchange Membrane) fuel cells for the on-board power system. Nowadays, the use of these systems is limited to aircraft that require low power demand such as small UAVs and ultra-light airplanes. This solution has always been considered appealing, but just recently has started to become also practical because of the dramatic decreasing of the specific weight of the fuel cell stacks
