Deposition of Pt and Pt-Ru Nanoparticles on RuO2.xH2O Using Microwave Method for Direct Methanol Fuel Cells

J. P. Zheng and V. Tiwari
Abstract—An easy and quick way to deposit platinum (Pt)-ruthenium (Ru) alloy nanoparticles on hydrous ruthenium dioxide (RuO2.xH2O) as supporting materials was developed using microwave heating. The x-ray diffractometer and selective area electron diffraction (SAED) showed that Pt-Ru alloy was formed. The transmission electron microscopic (TEM) image showed that average size of Pt-Ru was about 2-3 nm. Cyclic voltammogram of a Pt-Ru/RuO2.xH2O electrode showed high specific capacitance due to the protonation reaction in the acidic electrolyte and catalytic activity, including the methanol oxidation. The new Pt-Ru/RuO2.xH2O can be used as anode electrode materials in monolithic fuel cell/supercapacitor hybrid energy devices, since it has already been demonstrated that a layer of RuO2.xH2O sandwiched between anode catalytic layer and a membrane improved the dynamic response of the direct methanol fuel cell (DMFC).

Index Terms—Direct methanol fuel cell, super capacitor, hybrid, and RuO2.xH2O.
