Abstract
Three different compositions of Pt-Re-Sn/C catalysts were prepared using the impregnation method, and their performance was tested using a direct ethanol fuel cell (DEFC). The effect of various operating parameters like cell temperature, ethanol solution flow rate, ethanol concentration, anode diffusion layer, and oxygen flow rate were studied using Pt-Re-Sn (20:5:15)/C as metal catalyst. The performance of the DEFC was found to be increased by increasing the cell temperature. Also, the effect of different supports is studied, and its performance was tested using the DEFC. The percentage of different products of ethanol electro-oxidation was also studied.
