This work presents a new method to study the ethanol oxidation reaction in a functional
fuel cell adapting the single cell on an ATR-FTIR accessory. Using this configuration it was
possible to observe the formation of the main products d acetaldehyde and acetic acid d
and also measure the decay of the ethanol concentration at various temperatures.
Furthermore, it was ascertained that the increment of power density with the temperature
increase in the Pt/C anode fuel cell favors the acetaldehyde production. The proposed setup
is a very promising characterization technique for studies of in situ electrochemical
oxidation of small organic molecules.
