Methane and ethanol were directly fed to the fuel cells without water or any oxidizing agent. Fuels were interchanged during continuous polarization and fuel cell accumulated ~160 hours of operation delivering comparable current densities for each fuel. This result was supported by stability curves, impedance spectroscopy, and energy-dispersive X-ray spectroscopy analyses, which showed that deleterious carbon deposits were absent in the anode of tested fuel cells.2885-2891openAccessfuel cellsfuel substitutionsolid oxide fuel cellselectrolytesyttrium oxideszirconium oxidescerium oxidescatalystslayersanodeshydrogenethanolimpedancex-ray spectrometersspectroscopymethanespectroscopyArtigo de periódico15710.1149/05701.2885ecsthttps://orcid.org/0000-0003-0708-2021
