The homemade catalysts were characterized using a transmission electron micrograph (TEM) and X-ray diffraction (XRD). The cyclic voltammogram analyses revealed that the Pt/MWNTs showed a higher catalytic activity for dimethyl ether electro-oxidation, compared with the Pt/Vulcan XC-72 catalyst. The membrane electrode assembly (MEA) with the Pt/MWNTs anode catalyst presented the maximum power density of 38.4 mW cm-2, which was higher than that with the Pt/Vulcan XC-72 one (32.4 mW cm-2). Moreover, the performance decay rate of the MEA with Pt/MWNTs was lower than that with Pt/Vulcan XC-72 (after a 56 h test). It indicated that the Pt/MWNTs can be expected to be a more suitable catalyst for the DDFC.
