The ethanol electro‐oxidation on platinum catalyst in acid media leads to the formation of acetaldehyde and acetic acid as main products. Another problem is the poisoning of the electro‐catalyst surface with CO formed during the fuel oxidation reaction. To increase the performance of Direct Ethanol Fuel Cells (DEFCs) it is necessary to develop new electrode materials or modification of the existing...
This work has focused on the development of metallic amorphous microparticulated alloys of composition Ni59Nb40Pt0.6Cu0.4 and Ni59Nb40Pt0.6Cu0.2Sn0.2, obtained by mechanical alloying (MA), for use as anodes in direct alcohol fuel cells (DAFCs). The addition of copper modifies the electronic properties of platinum due to its special electronic configuration (3d104s1), demonstrating a better performance...
