Abstract

Single-element all-perovskite solid oxide fuel cells (SOFCs) incorporating (LSGM) electrolyte, (LSGMn) anode, and (LSC) cathode were fabricated by a combination of dry pressing and screen printing. Deleterious effects due to interfacial reactions between electrolytes and anodes or cathodes were not found. Furthermore, an increase of SOFC conductivity was observed due to interdiffusion between electrolytes and electrodes. The maximum power density of the single-element all-perovskite SOFC cell was determined to be 250 and , respectively, at 700 and under test conditions with at the anode side and at the cathode.
