An empirical model to evaluate the contribution of alloyed and non-alloyed tin to the ethanol oxidation reaction on Pt-Sn/C catalysts based on the presence of SnO2 and a Pt(1-x)Snx solid solution: Application to DEFC performance
An empirical model is proposed to evaluate the contribution of alloyed and non-alloyed tin in Pt-z-Sn/C catalysts to the performance of direct ethanol fuel cells (DEFCs). The model is based on the presence of SnO2 and a Pt(1-x)Sx solid solution in the bimetallic catalysts. The model predicts the dependence of the performance of a single DEFC on the total Sn content and the degree of alloying of Pt-z-Sn/C catalysts used as the anode material.
