Abstract: This paper presents the efficient use of platinum catalyst ruthenium with in the anode of a Direct Methanol Fuel Cell (DMFC). This is achieved by depositing platinum and ruthenium nano-particles on the pre-refluxed multi-walled carbon nano-tubes (MWCNT). MWCNTs were synthesized using the Chemical Vapor Deposition (CVD) with floating catalyst technique. The synthesized carbon nanotubes (CNT) were refluxed in 12M nitric acid to produce anchoring sites on the surface of the CNT. The platinum and ruthenium nano-particles were in a ratio of (3:1). These particles are deposited on the surface of the CNT at 60 wt % by reduction in ethylene glycol. Transmission micrograph (TEM) and scanning electron micrograph (SEM) images show the success of the deposition method.
Keywords: DMFC, floating catalyst CVD, multi-walled carbon nano-tubes, platinum-ruthenium nano-particles.
