Abstract

In this research, we investigated the hydrogen-gas filling characteristics of ultra-light composite tanks that have a plastic or aluminum liner inside the composite shell. The study was performed for different gas and tank temperatures. The temperature changes at various positions in the Type-4 tank during hydrogen-gas filling were monitored in order to understand the effects of the filling conditions. The results were compared with those obtained for a Type-3 tank. As the filling speed was increased, a quicker temperature rise was observed, and the temperature distribution over the entire region showed significant discrepancies.

본 연구에서는 연료전지자동차의 초경량 복합재료 수소 탱크에 대한 수소 충전 특성을 파악하고, 충전 조건에 따른 수소 탱크의 안전성을 확인하기 위해 플라스틱 라이너를 사용하는 Type 4 수소 탱크와 알루미늄 라이너를 사용하는 Type 3 수소 탱크에 대해 수소 충전 시, 수소 탱크 내부의 가스 온도 및 압력 변화, 라이너 및 복합재료 층의 온도 변화 등을 측정하여 그 특성을 고찰하였다. 그 결과 충전 속도가 증가함에 따라 탱크 내부 가스의 온도가 증가하였고, 탱크 내부 가스의 온도 분포가 다르게 나타났다.
