고분자전해질 연료전지용 Poly(arylene ether sulfone) 막의 특성 = Characteristics of Poly(arylene ether sulfone) Membrane for Proton Exchange Membrane Fuel Cells

다국어 초록 (Multilingual 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.
