Abstract

The effort to realize the concept of stratospheric airship, which can fly at about 20km altitude, has been persevered since late 1980's. Referring to the feasibility study of ensuring the flight duration of the airship over 1year, total weight is about 30 tons, the length is about 200m. There are lots of key technologies to be solved to develop the system, and one of the essential prerequisite technologies is regenerative fuel cell system. In this paper, design requirement of regenerative fuel cell system is introduced with the feasibility study results of the challenging stratospheric airship.
