We have developed high performance anode for medium-temperature solid oxide fuel cells. Mixed conducting samaria-doped ceria (SDC) particles were employed in combination with highly dispersed metal electrocatalysts on their surfaces. A small amount of Ni nanoparticles (6-8 vol%) enhanced the anode performance significantly at 700-800degreesC in humidified H-2. The dispersion of nanometer-sized Ni increased the reaction area (contact portion with SDC) more effectively than micrometer-sized Ni in the cermet-type anode. (C) 2003 The Electrochemical Society.
