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.10585-10591openAccesselectrocatalystsethanoloxidationplatinumcarbonfourier transform spectrometersinfrared spectraalcohol fuelsdirect ethanol fuel cellsArtigo de periódico3810.1016/j.ijhydene.2013.06.026https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-9287-6071
