Abstract:
Electrocatalytic oxidation of methane over anodes in single-chamber solid oxide fuel cells, 0-10 wt % Pd-30 wt % Ce 0.8 Sm 0.2 O 1.9 (samaria-doped ceria, SDC)- Ni | SDC | Sm 0.5 Sr 0.5 CoO 3 , was studied in a mixture of methane and air between 450 and 550°C. The addition of a small amount of Pd (0.145 mg cm −2 ) to the anode significantly promoted the partial oxidation of methane by oxygen to form hydrogen and carbon monoxide, which resulted in electromotive forces of ca . 900 mV from the cell and extremely small electrode-reaction resistances of the anode. The peak power densities, when using a 0.15 mm thick SDC electrolyte, reached 644, 467, and 269 mW cm −2 at 550, 500, and 450°C, respectively. © 2002 The Electrochemical Society. All rights reserved.
