Direct ethanol fuel cells (DEFCs) are very promising as they are capable of giving high-power
density at low and intermediate temperatures. It has concerned a great deal of interest as a power
source in plentiful applications because ethanol is a nontoxic, safe, and high density energy carrier,
which is commonly available from the reformation of numerous kinds of biomass [1,2]. Several
researches have been done on the using of metal oxide to improve Pt catalytic EOR activity.
PtSnO2 and PtSn alloy catalyst were synthesized and the investigation of the products
demonstrated that the addition of SnO2 improved the total oxidation to CO2. SnO2 is recognized
for being potentially able to provide OH-species to oxidize toughly bound intermediates such as
CO [3].In the present work, an experimental study on the performance of a passive DEFC is
described. The PtSnO2/C (3:1) and Pt/C are used for anode and commercial Pt/C is used for anode
material. A maximum power density of 1.78 mW cm-2, was obtained using a Nafion 115
membrane, 4 mg cm-2 of PtSnO2 and 3 mg cm-2 of Pt on the anode and cathode catalyst layer.
