Fabrication and Characterization of Miniaturized SOFC by Colloidal Process

Abstract

Miniaturized solid oxide fuel cells (SOFCs) have drawn increasing interest as next generation portable and mobile power sources recently. For these applications, operation and fabrication temperature reduction along with miniaturization of SOFCs should be achieved. For these purposes, we investigated miniaturized SOFC fabrication through various processing techniques including colloidal processes. Anode- supported cells with thin electrolytes and well-controlled electrode structures are obtained by the combination of the processes such as spin-on, electrostatic spray deposition, and microwave sintering at lower fabrication temperature. The properties of cell components and the overall cell performance have been characterized and will be presented.
