Abstract

외부 개질형 MCFC 연료전지 시스템에 적용할 평판형 개질기를 제작하고 성능 시험을 수행하였다. 연소실과 개질실의 온도 분포를 측정하고 수소 연소율, 메탄 전환율 및 생성물 조성을 분석하여 개질기 초기 온도와 공간 속도에 대한 운전 특성을 고찰하였다. 80%의 연료이용률로 운전되는 연료 전지 시스템을 모사한 조건하에서 개질기의 정상 상태 운전이 가능하였고 99% 이상의 수소 연소율과 98% 이상의 메탄 전환율을 유지하면서 수 kW급의 수소를 생산할 수 있었다. 개질기 운전 중 측정된 온도 분포 곡선에서 개질기내 위치에 따른 반응 진행 상태를 보여주는 endotherm이 관찰되었다.

The plate reformer consisting of combustion chamber and reforming chamber, which can be integrated in the MCFC fuel cell system, has been prepared and the performance test was carried out. In order to study the effect of initial temperature and space velocity on the performance of reformer, the temperature profiles were measured and the conversion of hydrogen and methane and the composition of products were analyzed. Upon the operating condition based on fuel cell stack having fuel utilization of 80%, the reformer was able to generate hydrogen for several kW fuel cell stack, maintaining the hydrogen conversion of above 99% and methane conversion of 98%. The temperature profile recorded during the test showed the endotherm representing the operating state of reformer.
