Abstract

Bimetallic PtRu catalysts is a conventional anode catalyst commonly used for direct methanol fuel cell application (DMFC). However, the low methanol oxidation reaction (MOR) rate has been a significant constraint to the DMFC performance and power output. Besides, expensive PtRu prevents DMFCs from being commercially as compare to batteries. Therefore, PtRu catalyst loading needs to be reduced and alternative metal should be added to ensure DMFC performance is maintained. Hence, the main objective of this study was to analyze potential alternative catalysts metals. Four potential catalysts, ferum (Fe), nikle (Ni), aurum (Au) and palladium (Pd) were simulated using computational chemistry. Material Studio software used to analyse free energy analysis and adsorption energy. The analysis using Material Studio software showed that the ferum (Fe) and nickel (Ni) had the same performance as Pt and Ru. Then, DMFC single cell was fabricated using PtRuFeNi nanocatalyst supported with multi -walled carbon nanotube (MWCNT) and found high DMFC performance compared to PtRu catalysts. The performance of single cell DMFC produced by PtRuFeNi/MWCNT nanocatalyst is 11 mW with optimum current density of 33 mA.cm-2
