dc.description.abstractIn this chapter, an overview of electro-catalysts for direct ethanol fuel cells based on polymer electrolyte membranes is presented, with special attention given to the alkaline anion exchange membrane-based devices. Considering the anodic reaction, it is evidenced that a substantial effort has been dedicated towards increasing the fuel cell efficiency by developing electrocatalysts with higher catalytic activity. In this sense, palladium is pointed out as a promising substitute to platinum with regards to electrocatalytic activity, price and element availability. Furthermore, palladium-based nanoparticles are pointed out as the electrocatalysts with the highest electrocatalytic activity for ethanol electro-oxidation in alkaline media. Taking into account the support materials for the electrocatalysts nanoparticles, it was possible to observe an evolution in carbon-based materials, first carbon nanotubes overcame the carbon black, where more recently, graphene is addressed as the best support choice for catalysts nanoparticles. Different efforts have been made to improve the properties of the support materials, such as doping with nitrogen or with metal oxides like TiO2, for example. Considering the cathode materials, the main goal is to develop catalysts with enhanced activity to the oxygen reduction reaction as well as tolerance to ethanol molecules that crossover the electrolyte membrane.pt_BR
