Can fuel cell and battery energy storage improve aircraft performance?
Recent developments in fuel cell (FC) and battery energy storage technologies bring a promising perspective for improving the economy and endurance of electric aircraft. However, aircraft power system configuration and power distribution strategies should be reasonably designed to enable this benefit.
Should onboard energy management be integrated in the aircraft design methodology?
To improve these results, it has been proposed to integrate onboard energy management in the aircraft design methodology ( Perullo and Mavris, 2014 ). In the context of hybrid vehicles, onboard energy management is defined as the management of the different energy sources available onboard during a mission ( Serrao et al., 2011 ).
