Abstract

Ba0.5La0.5CoO3 (BLC) and Pr1.9 (Ni,Cu,Ga)O4 (PNCG) composite cathode were investigated to enhance electrochemical performance in solid oxide fuel cells using Sr- and Mg-doped lanthanum gallate (LSGM) electrolyte films at intermediate temperatures (773-973 K). Effect of the calcination temperature of the composite cathode was studied on chemical compatibility, area specific resistance (ASR), and power generation property. ASR of the composite cathode was smaller than that of SSC but increased with increasing calcination temperature by chemical reaction. Improved maximum power density of 1.270 and 0.146 Wcm-2 at 973 K and 773 K was achieved on a single cell using BLC-PNCG composite as cathode on LSGM film.
