The present invention relates to a system for simply regenerating ammonia borane from ammonia borane (polyborazylene) dehydrogenated after being used, by means of a process using a supercritical fluid. Compared to a conventional system, a process system of the present invention is simple, so ammonia borane may be mass-produced. Regeneration yield is excellent, so high price ammonia borane may be usefully recycled. Accordingly, the system may be useful in the fields of hydrogen gas storing materials and fuel cells. The system comprises: an ammonia borane regenerating reactor having a magnetic agitator; a used ammonia borane and solvent feeding unit connected with the regenerating reactor through a used ammonia borane and solvent feeding line; a liquefied supercritical fluid tank connected with the regenerating reactor through a liquefied supercritical fluid feeding line; a supercritical fluid raw ingredient feeding unit connected with the liquefied supercritical fluid tank through a supercritical fluid raw ingredient feeding line; and a chiller for liquefying supercritical fluid raw ingredients. 본 발명은 초임계 유체를 이용한 공정에 의해서 사용 후의 탈수소화된 암모니아 보란 (폴리보잘린)을 암모니아 보란으로 간단하게 재생하는 시스템에 관한 것으로소, 기존에 비하여 공정 시스템이 간단하여 암모니아 보란의 대량 생산이 가능하고, 재생 수율이 우수하여, 고가의 암모니아 보란을 유용하게 재사용할 수 있어 수소가스 저장재 및 연료전지 분야에서 유용하게 사용할 수 있다.
