Abstract
Abstract High catalytic activity PrBaCo 2 O 5+ δ (PBC) cathode with impregnated Sm 0.5 Sr 0.5 CoO 3− δ (SSC) was investigated as a highly active cathode for intermediate-temperature SOFCs (IT-SOFCs) with BaZr 0.1 Ce 0.7 Y 0.2 O 3− δ (BZCY7) electrolytes. The nanoscale impregnated SSC particles were deposited on the surface of the PBC framework. The single cell with impregnated SSC cathode was tested from 600 to 700 °C with humidified hydrogen (~3% H 2 O) as the fuel and the static air as the oxidant, and showed higher performance than the cell with pure PBC cathode. The results indicated that the impregnation method can be promising ways to improve the catalytic activity of cathode for proton-conducting SOFCs.
