Abstract

Due to the climate changing, the world's countries are tightening regulations on CO2 and air pollutants emission to solve them. In addition, eco friendly vehicles is increasing to replace automobiles in internal combustion engine. Recently, the government is supporting the expansion of hydrogen refueling infrastructure and localization of core equipment in refueling facilities according to the hydrogen economy road map. In this study, design of the Excess flow limiting device in FCEV cylinder valve using by finite element analysis and performed performance tests on prototype. Major test results as hydrostatic strength, continued operation, operation, pressure impulse, leakage showed that the excess flow limiting device meets the performance requirements according to ISO 12619-2 and ISO 12619-11.

기후변화에 대응하기 위해 세계적으로 이산화탄소 및 대기오염 물질 배출 규제가 점차 강화됨에 따라 내연 기관 자동차를 친환경 자동차로 전환하려는 추세이다. 이는 정부의 수소 에너지 활성화 정책에 따른 충전 인프라 구축, 충전 설비 핵심 부품의 국산화 지원으로 가속화되고 있다. 본 연구에서는 유한 요소 해석을 통해 수소 연료 전지 자동차 용기 밸브의 과류 방지 장치를 설계하고, 시험을 통해 성능을 평가하였다. 주요 시험 항목인 정수압, 연속 작동, 압력 임펄스, 누설, 작동 시험을 ISO 12619-2, ISO 12619-11의 시험 방법에 따라 수행한 결과 요구 조건을 만족함을 확인하였다.
