Direct Oxidation of Methane by Pd–Ni Bimetallic Catalyst over Lanthanum Chromite Based Anode for SOFC

Abstract Steady generation of electricity with dry CH4 fuel, 150 mW·cm−2 at 1073 K and 360 mW·cm−2 at 1173 K, was successfully performed by a low loading of Pd–Ni bimetallic catalyst on a lanthanum chromite based porous-composite anode for solid oxide fuel cells (SOFC). The amounts of carbon deposition were quite small under the open and closed circuit conditions. The electrocatalytic activity of the Pd–Ni catalyst was significantly higher than that of Pd or Ni catalysts.
