Structural investigation of electrochemically active ceramic anodes for next-generation solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs)

Abstract

Electrochemically active ceramic anodes for next-generation solid oxide fuel cells (SOFCs) were studied by controlling the anode structure at the submicro-scale. Specifically, the effect of highly porous metal-ceramic structures on electrochemical properties such as power density and conversion efficiency at an intermediate temperature was investigated. Moreover, the structural control technology of active fuel electrodes for direct hydrocarbon SOFCs was discussed. In addition, high-temperature steam solid oxide electrolysis cells (SOECs) with highly porous fuel electrodes have been developed for advanced ceramic reactors.
