Ultimate Performance of Anode-Supported SOFC by Realizing Thin-Film Electrolyte and Nano-Structure Electrode

Abstract

Thin-film electrolytes and nano-structure electrodes are essential components to lower the operation temperature of SOFCs. We will discuss how to precisely assess the impact of the thin-film electrolyte and the nano-structure electrodes which are realized on the anode supports, a realistic SOFC platform (anode-supported TF-SOFC). A peak power density over 500 mWcm -2 at 500 o C is obtained, which we believe is nearing the highest level that the SOFC can reach while using the common SOFC materials and platforms, by changing the dimension of the cell components. The potential and limitations of anode-supported TF-SOFCs in achieving the critical low-temperature performance will be discussed.
