Abstract

Each of power systems of solar cell and fuel cell were configured and validated for long endurance UAV, as the preliminary research for the integration of power systems. Solar power system consisted of solar modules fabricated by solar cells of Sunpower's C60, commercial solar MPPT controller and Li-po battery, and then was validated. The re-start characteristics of hydrogen production from $NaBH_4$ hydrolysis was validated for operating the commercial fuel cell. The average voltage drop of Li-po battery in solar power system was -2.9 V/hour. The performance of re-start characteristics of $NaBH_4$ hydrolysis was stable in sequence mode of mission profile. Each of single systems were satisfied for the proposed mission profile.

장기체공 무인기용 동력원으로 활용될 태양전지-연료전지 복합 동력원 통합 전 단계로 태양전지와 연료전지 개별 시스템에 대한 구성과 평가를 수행하였다. 태양전지 시스템은 Sunpower사의 C60 태양 전지를 활용한 모듈, 상용 태양광 MPPT 제어기, 그리고 리튬-폴리머 배터리를 이용하여 구성하고 평가하였다. 연료전지 시스템 운용을 위하여 $NaBH_4$ 가수분해를 이용한 수소공급장치의 재시동 특성을 확인하였다. 태양전지 시스템에 속한 배터리의 성능이 평균 -2.9 V/hour임을 확인하였다. 수소공급장치의 재시동 특성이 운용임무 조건에서 안정적인 성능이 나타남을 확인하였다. 본 연구를 통하여 제시된 임무조건에서의 각 단일시스템의 성능이 적합함을 확인하였다.
