840 Fuel Cell Test System


840 Advanced Fuel Cell Test System은 연료 전지 연구 및 대학 교육 프로그램을 위한 턴키 테스트 스테이션입니다. 840은 통합된 벤치탑 장치로  컴퓨터에서 완전한 제어가 가능하며 소형에서 대형 싱글 셀 또는 숏스택과 함께 사용하도록 설계되었습니다.


모델 840은 최대 12 SLPM의 가스 유량을 필요로 하는 응용 분야를 대상으로 하며 검증된 850 연료 전지 테스트 스테이션을 기반으로 합니다. 840은 RH 사이클링에 이상적인 넓은 범위의 정확한 유량 제어를 위해 애노드와 캐소드 각각 두개의 MFC 가 있습니다. 또한 애노드 및 캐소드 가스를 3개 중 한개를 선택할 수 있는 소프트웨어로 제어되는 입력 가스 선택 밸브와 추가 전압 및 온도 측정을 위한 16채널 데이터 수집 모듈이 포함되어 있습니다.


840은 정확하고 광범위한 전류 측정을 위해 Scribner의 890 다중 범위 전자 로드를 사용합니다. 또한  840에는 스테이션 작동 및 실험을 제어하기 위한 업계에서 가장 강력하고 사용자 친화적인 애플리케이션 소프트웨어인 FuelCell®이 함께 제공됩니다.
