Resumo
The effect of ethanol concentration on the direct ethanol fuel cell (DEFC) performance and products
distribution were studied in situ using a single fuel cell/ATR-FTIR setup. The experiments were performed at 80 C using commercial Pt3Sn/C as anodic catalyst and the concentrations of ethanol solution
were varied from 0.1 to 2.0 mol L1
. An increase in power density was observed with the increase of
ethanol concentration to 1.0 mol L1
, while the band intensities analysis in the FTIR spectra revealed an
increase of acetic acid/acetaldehyde ratio with the increase of ethanol concentration. Also, from FTIR
spectra results, it could be concluded that the acetic acid production follow parallel mechanisms; that is,
it does not require the presence of acetaldehyde as an intermediate.
