An Experimental Study of Short Stack on the Performance of the Proton Exchange Membrane Fuel Cell for the Residential Power generation

소형 모듈 스택을 이용한 가정용 연료전지 성능의 실험적 고찰

Proton Exchange Membrane Fuel Cell (PEMFC) is an attractive candidate for residential power generator due to fast start-up and stop, high efficiency, low emission, and high power density. In this study, we employ short module stack to understand the performance of the unit cell of the stack in terms of operating temperatures. To simulate the practical fuel cell stack of residential power generator, the structure and active area of the short module stack is kept the same as that of the practical fuel cell. The results shows that the electric potential of short module stack is different from the number of cells times the potential of unit cell because of cell-to-cell variation.
