    • Abstract

       

      Herein, carbon felt (CF), a porous carbonaceous material is used as an anode in a direct methanol fuel cell (DMFC) application. In order to enhance the electrochemical activity of this electrode, modification of the CF electrode is performed with a polymeric-platinize nanocomposite by a pure electrochemical method. In the modification process, 4-methyl-1,2-diaminobenzene is electropolymerized on the CF surface and then, Pt nanoparticles are electrodeposited on this substrate. Physical characteristics of the synthesized nanocomposite, Pt/p-MDAB/CF, are investigated by field emission scanning electron Microscopy and energy-dispersive Xray spectra. The electrochemical studies such as cyclic voltammetry, chronoamperometry, and electrochemicalimpedance spectroscopy prove the Pt/p-MDAB/CF superiority over Pt/CF towards methanol oxidation. This superiority that results from the cooperation effect between carbonaceous-polymeric layer and Pt nanoparticles, introduces Pt/p-PDAB/CF as the suitable candidate anode for methanol oxidation reaction (MOR).
