GC를 이용한 고분자전해질형 연료전지의 공기극 채널 내 산소 농도 분포에 관한 실험적 연구
An Experimental Study on Measurement of Oxygen Concentration in the Cathode Channel of PEMFC by Using GC
초록
Fuel cell has been well known as a clean alternative power for vehicles. Recently, an experimental technique has been developed measurement of species and distributions by using gas chromatograph. In this study, cathode channel oxygen distributions as various conditions were investigated using gas chromatograph and cell visualization. And discussed relation between flooding and oxygen concentrations. As a result of experiment, oxygen consumpt ion is affected wi th flooding. Flooding is observed in channel near hydrogen inlet, and oxygen consumption is low at that region.
