Abstract

A portable power supply system for soldiers must be able to supply electric energy corresponding to the power consumption of combat support troops, and have a carrying load in a range that does not impair the combatant's ability to execute operations. In particular, as the total required power of combat equipment increases with the advances in the future soldier system, a portable, lightweight power supply system with high efficiency is essential. A fuel cell has a high energy-to-weight density compared to lithium batteries, which are used mainly as a military power source system. Therefore, it is capable of miniaturization and lightweight, making active R&D to a portable power supply system. In this paper, the characteristics of the fuel cell applied as a portable power supply system, and the R&D trends of domestic and foreign military portable fuel cell systems were investigated. The current status of domestic technology compared to the level of foreign development was analyzed. In addition, future technology development plans are presented based on the consideration factors when developing a portable fuel cell (power supply stability, portability, and cost reduction) so that it can be used when establishing a plan on the development of a portable fuel cell system for the future soldier system.

병사용 휴대형 전원은 전투원의 작전 수행 능력을 해치지 않는 범위의 휴대 하중을 지님과 동시에 전투장비의 소비전력에 대응하는 전기에너지를 공급할 수 있어야 한다. 특히 미래병사체계의 경우 전투장비의 고성능화에 따라 장비의 총 요구전력이 증가하고 있으므로 경량 고효율 특성을 가지는 휴대형 전원 개발이 필수적이다. 연료전지는 군용 전원으로 주로 적용되던 종래의 리튬 전지에 비해 중량 대비 에너지밀도가 높아 경량 소형화가 가능하여 휴대형 전원 시스템으로 활발한 연구개발이 진행되고 있다. 본 논문에서는 휴대형 전원으로 적용되는 연료전지의 특성을 살펴보고, 국내·외 군용 휴대형 연료전지 개발 현황을 조사한 후, 국외 선진 기술국의 개발 수준 대비 국내 기술 현황에 대해 분석한다. 또한, 미래병사체계용 전원으로의 적용을 위한 휴대형 연료전지 개발 시 고려해야할 주요 요소를 전력 공급 안정성, 휴대 용이성, 비용 절감 세 가지로 분류하고, 이와 관련된 기술을 중심으로 발전방안을 제시하여 향후 연료전지 기반 개인병사 체계용 휴대형 전원 기술 발전방안 수립 시 활용할 수 있도록 한다.
