Abstract

Recently, there are many efforts focused on development of more economical non-fluorinated membranes for use in PEMFCs (Proton Exchange Membrane Fuel Cells). In this study, characteristics of poly(arylene ether sulfone)(PAES) were compared with fluorinated membrane at PEMFC operation condition. I-V polarization curve, hydrogen crossover, electrochemical surface area, membrane resistance and charge transfer resistance were measured. PAES membrane showed similar performance compared with fluorinated membrane at 100% relative humidity, but the performance of PAES membrane decreased largely due to low ionic conductivity at low relative humidity.

최근에 저가의 고분자전해질 연료전지(Proton Exchange Membrane Fuel Cells, PEMFC)용 비불소계 전해질 막 연구개발이 활발히 진행되고 있다. 본 연구에서는 PEMFC 운전 조건에서 Poly(arylene ether sulfone)(PAES) 막과 불소계막의 특성을 비교하였다. I-V 분극곡선, 수소투과도, 전기화학적 표면적, 막저항 및 부하 전달 저항 등을 측정 분석했다. PAES 막은 상대습도 100%에서는 불소계 막과 비슷한 성능을 보였으나 낮은 상대습도에서 이온전도도가 낮아 성능감소가 컸다.
