Resumo

Electrolyte-supported single fuel cells based on yttria-stabilized zirconia components with a ceria-based catalytic layer added to the anode were operated with three different fuels: hydrogen, methane, and ethanol. 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 similar to 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.
