Effects of nano structure of platinum electrocatalyst on electrochemical behavior of new Nafion/Pt/GDL electrode

Mostafa Dehghani Mobarakeh


In this study, effects of structural properties of new Nafion/Pt/GDL electrode on electrochemical behaviors of electrodes were investigated. For this purpose a new gas diffusion electrode based on Pt-coated Nafion membrane was fabricated. Electroless method was used to deposit platinumon Nafion membrane. The electrochemical and structural properties of samples were evaluated by electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV), scanning electron microscopy (SEM) and X-ray diffraction. In the optimum condition; 85 m V dec-1 for Tafel slope, 2×10-3 A for exchange current density (i0) and 8? for charge transfer resistance (Rct) were obtained. For this electrode the platinum particle size is 4 nm.
