Abstract
즉, 본 발명은 연료전지 차량의 주차시 외기로부터 공기극으로 산소가 확산되는 것을 미연에 차단하고자, 산소농도가 기준치 이상이면 공기극에 수소를 주기적으로 퍼지함으로써, 항상 수소극에서의 수소와 산소 계면 형성을 억제할 수 있고, 그로 인해 연료전지 스택의 전극막 어셈블리에 대한 내구성 저하를 방지할 수 있도록 한 연료전지 시스템 운전 방법을 제공하고자 한 것이다.
Description
도 2는 본 발명에 따른 연료전지 시스템 운전 방법의 일 실시예로서, 공기극 측의 산소 농도에 따른 셀전압을 측정한 그래프,
도 3은 본 발명에 따른 연료전지 시스템 운전 방법의 일 실시예로서, 주차 후 스타드 업 시, 공기극 측 산소 농도에 따른 스택 전압 거동을 측정한 그래프,
Claims (5)
- 연료전지 차량의 시동 오프 상태에서의 주차 시, 주차 시간에 따른 산소 농도를 기반으로 공기극에 대한 수소 퍼지 주기를 결정하는 단계;
결정된 수소 퍼지 주기마다 공기극에 수소를 퍼지시켜 공기극에 존재하는 산소를 제거하는 단계;
를 포함하고,
상기 수소 퍼지 주기는 주차 시간이 증가함에 따라 공기극 내의 산소 농도가 기준치를 초과하는 시점으로 정해진 주차 시간별 공기극 산소농도 변화 데이터를 기반으로 결정함과 더불어 상기 산소 농도 기준치는 공기극내에 산소를 강제 유입시켜 스택의 산소 농도별 개회로전압을 모니터링하고, 모니터링된 개회로전압이 기준치 이상으로 증가되는 시점에서의 산소 농도로 정하며,
연료전지 차량의 주차 후, 스타트 업 시, 고전위 유지 시간없이 곧바로 수소극 및 공기극에 각각 수소 및 공기가 동시에 공급되는 것을 특징으로 하는 연료전지 시스템 운전 방법.
- 삭제
- 삭제
- 청구항 1에 있어서,
상기 산소 농도는 공기극 측에 장착된 산소센서에 의하여 측정되는 것을 특징으로 하는 연료전지 시스템 운전 방법.
