Main Parameters Quoting for Components of a Hybrid Power Source for HAPS

Abstract

This paper presents a method for quoting of necessary power of a hybrid power source on board of High Altitude Pseudo-Satellites (HAPS). Considered power source contains as main energy sources a fuel cell and a photovoltaic panel which function complementary daytime and nighttime. For unexpected situations a small capacity battery is provided in the system aiming to ensure the system functioning along 15 minutes. Photovoltaic panels feed also an electrolyzer which uses water produced by the fuel cell and obtains hydrogen in order to recover the fuel reserve on board for next night functioning.
