Fuel cells, as an alternative technology to reduce dependence on fossil fuels, have an important role today for a cleaner environment. The R&D studies in fuel cell technology has been increased over the last 20 years to improve air quality and reduce CO2 emissions [1]. Glycerol, as a fuel and a by-product of biodiesel production, has the advantages of being cheap, readily available, and non-toxic. Therefore, glycerol fuel cells are of importance to evaluate glycerol as an environmental-friendly fuel. In this regard, the anode catalysts studied in literature on the glycerol electro-oxidation reaction (GOR) are mainly Pt, Pd, Au, Cu, Zn on various supports [2-3]. Also, it was reported that Pd and Cu help to reduce the cost and increase the glycerol activity in GOR.
In this study, PdCu/C (wt.%20 PdCu) and Pd/C (wt.%20 Pd) catalysts were prepared via microwave assisted polyol method and tested for glycerol electro-oxidation reaction. Pd acetate, copper chloride and carbon were dissolved in ethylene glycol prior to NaBH4 addition. Later, the solution was heated in a microwave oven for 150 seconds at 700 W and aged in an ice-water bath for 24h. The solution was filtered and washed three times and dried in an oven at 80 ℃ for 18h. Characterization of the catalysts was performed by X-ray diffraction, electrochemical active surface area, cyclic voltammetry, and chronoamperometry. The GOR activity of the catalysts was found to be 27.03 mA/cm2 and 7.88 mA/cm2 for PdCu/C and Pd/C, respectively.
