Abstract

Direct methanol fuel cells (DMFCs) have attracted much attention over the past decades due to their ease of handling and ability to operate at low temperature with high efficiency. Here, the DMFC catalyst was further investigated to determine the optimum conditions for achieving the optimum DMFC performance by using PtRu catalyst supported by TiO2 nanotubes (TNTs) and Carbon. TNTs are one-dimensional (1D) nanostructures that able to exists as bundles tubes with range of diameter between 30 and 80 μm and length of 10-220 μm. PtRu/TNT-C was synthesized and further used as an anode catalyst in the methanol electro-oxidation reaction (MOR), and the results were compared with those of previous studies. The optimum amount of catalyst loading (PtRu) and catalyst support ratio based on TNTs (TNT: C) were investigated by design of experiment (DOE) using traditional one-factor-at-a-time (OFAT) and standard Response Surface Methodology (RSM) design. RSM is a statistical and mathematical method for optimization that employed experimental design to generate multiple regression equation regarding to the factors involved. From the analysis, the optimum PtRu loading and catalyst support ratio (TNTs) were 20.92 wt% and 40.11 wt%, respectively. The relationship of the two factors was thoroughly investigated by cyclic voltammetry (CV) analysis. In this study, PtRu/TNT-C showed good electrochemical performance, and the optimized conditions provided an optimum current density of 51.9 mAcm-2. This study proved that PtRu/TNT-C is an excellent catalyst for methanol electro-oxidation with highest current density recorded compared to the other researcher with similar condition.
