>> Nafion ionomer located in electrode helps to increase the platinum utilization and proton conductivity.To achieve higher performance in PEMFCs, it is important an optimum Nafion content in the electrode. As theplatinum loading and fabricated method depend on the optimum Nafion content. In this study, we have examinedthe interrelationship between platinum loading and Nafion content fabricated by decal transfer method. For electrodes with 0.25 and 0.4 mg/cm 2 Pt loading, best performance was obtained at 25 wt.% Nafion ionomer loading.It is also found that MEA with 0.25 mg/cm 2 Pt, the optimum Nafion content appears differently at low and highcurrent density. Key words : PEMFC(), Nafion contents( ), MEA(-), Pt loading( ), Decal-transfer method() † Corresponding author : eacho@kist.re.kr [  : 2012.4.10  : 2012.4.23  : 2012.4.27 ] 1.                .
