Abstract

The sustainable production of electric power is a society's concern. The fuel cells PEMFC (Proton Exchange Membrane Fuel Cells) are promising for electric power generation for stationary applications in reason of the high potency density and low temperature operation. However, for PEM cells that use alcohol as fuel, several problems still exist that difficult their industrialization. In the intention of solving part of these problems, in this project two slopes will be developed: i) development of eletrocatalysts for ethanol oxidation and ii) tests of these catalysts and measures of current distribution of the cell operating with ethanol as fuel. In the attempt of increasing the electrocatalytic activity, a second and third metal have been added to the catalysts of Pt and Pt-Sn, respectively, usually used in this type of cells. The literature presents few works about Pt/C and Pt-Sn/C modified with rare earth (Ln). The present project aims for studying the effect of these metals in catalysts of Pt-Ln/C and Pt-Sn-Ln/C for ethanol eletrooxidation. The main objectives are to increase the efficiency of the ethanol oxidation reaction, to understand the reason of the variations in the catalytic activity, to evaluate the stability of the catalysts and to analyze the current distribution in the conditions of operation of the cell.
