Abstract

Hydrogen energy, a field of low-carbon substitute energy, can be produced by fossile fuel reforming and electrolysis of water etc. We developed 1kW class flat type reformer for PEM Fuel Cells. The PEMFC is highly sensitive to carbon monoxide because CO has detrimental effects on the performance of the fuel cell. Thus, reformed gas supplied to Fuel cell system, which maintained CO concentration below 10ppm. After applying optimum drive condition, reformed gas was measured with gas chromatography and could find out about each experimental condition of $H_2$ and CO concentration. As a results, The 1kW class plate type hydrogen generation system's optimum condition is A/F ratio ${\alpha}=1.3$, STR temperature 1023K, S/C ratio 3, and $PrOx1{\cdot}2$ 30cc/min. It turns out that installation of PrOx 2 stage is more efficient for reducing CO concentration.

저탄소 친환경 대체 에너지의 한 분야인 수소에너지는 화석연료의 개질 및 물의 전기분해 등 다양한 방법을 통해 얻어진다. 수소를 연료로 사용하는 연료전지인 PEMFC용 1kW급 평판형 수소생산시스템을 자체 개발하였다. FEMFC는 CO에 의한 오염에 민감하므로 공급되는 개질가스 중에 CO 농도는 10ppm 이하로 제거되어야 한다. 본 연구에서는 다양한 실험조건에서 $H_2$ 및 CO의 농도를 측정하여 최적의 운전조건을 확립하였다. 결과적으로 A/F ratio ${\alpha}=1.3$, STR temperature 1023K, S/C ratio 3, and $PrOx1{\cdot}2$ 30cc/min에서 최적임을 확인하였다. 또한 PrOx 2단이 CO 농도를 줄이는데 더욱 효과적임을 알 수 있었다.
