Research Abstract |
New electrocatalysts which enable direct methane use in solid oxide fuel cells (SOFCs) were examined. The dispersion of Co_<0.5>Ni_<0.5>O and PdCoO_2 particles into a porous-platinum-based anode respectively increased the cell performance in an SOFC using a stabilized-zirconia electrolyte. Among the catalysts studied, the increase was the most prominent for these oxides. Both the anodic polarization resistance and the production rates of CO, CO_2, and H_2 in the outlet gas showed a high catalytic activity for the electrochemical oxidation of methane. These results indicate the activation of the steam-reforming reaction caused by the formation of surface active sites in relation to the specific states of these oxides ; cation vacancy in the CoO-NiO solid solution and monovalent Pd ions in PdCoO_2.
