890ZV SOFC Test Load

벤치탑 모델 890ZV는 프로그래밍 가능한 전자 로드, 연료 및 온도 제어, 데이터 수집 기능으로 구성됩니다. 파워서플라이가 내장 돼 있어 890ZV는 연구, 실험실 및 교육용 소형 단일 셀 SOFC 작업에 특히 적합합니다.

890ZV는 비용과 크기에 최적화되어 있으며 추가 하드웨어 기능과 Scribner Associates의 FuelCell® 소프트웨어를 제공합니다.

890ZV는 일반적으로 SOFC 연료 전지, 적합한 퍼니스 및 연료 제어 장치와 함께 사용먀 Scribner 885 통합 연료 전지 Potentiostat과 호환됩니다.
