Its surface characteristics were systematically analyzed using XRD and TEM and anodic electrocatalytic activity was studied using a linear sweep voltammetry technique in 0.5 M H2SO4 + 1 M HCOOH. In addition, the voltage-current curve and power density of home-made AuPt-based membrane-electrode-assembly (MEA) and commercial Pt0.5Ru0.5-based MEA was measured at 60 degrees C in 9 M formic acid. The maximum power density of Au0.6Pt0.4-based MEA was 30% higher than that of PtRu-based MEA which were 200 mW cm(-2) and 155 mW cm(-2), respectively. (c) 2007 Elsevier Ltd. All rights reserved.
