제목 | Anodic electro-oxidation of alcohols using carbon-supported Pt based electrocatalyst for direct alcohol fuel cells (DAFCs) |
초록 | Fuel cells employing alcohols directly as fuel – direct alcohol fuel cell (DAFC) – are attractive as power sources for mobile, stationary and potable applications. The alcohol is fed directly into the fuel cell without any reforming process to extract H2 and is oxidized at the anode while oxygen is reduced at the cathode. This feature avoids problems related to production, purification and storage of hydrogen[1]. However, alcohols’ complete oxidation to CO2 is difficult due to the difficulty in C-C bond breaking and to the formation of CO-intermediates that poison platinum anode catalysts. It is well known that the catalytic activity of the metal is strongly dependant on particle shape, size and size-distribution[2]. In this study, we examine electrochemical oxidation properties of various alcohols (e.g. methanol, ethanol) using the cyclic voltammetry (CV) over different carbon supported Pt based catalysts whose structure was investigated by X-ray diffraction (XRD).
