Abstract
A samaria‐doped celia (SDC) interlayer was used to avoid unfavorable solid‐state reactions when using (LSC) as a cathode on yttria‐stabilized zirconia electrolyte. A porous LSC cathode prepared on a thin and dense SDC interlayer exhibited very high performance even at . The performance was enhanced further by dispersing a small amount of nanometer‐sized catalysts on the LSC surface. The current density on the cathode at an overpotential of was at in . ©1999 The Electrochemical SocietyKeywords
