Ceria-carbonate Electrolyte Ceramic Membrane for Intermediate and Low Temperature Solid Oxide Fuel Cells: A Review

Abstract

A solid oxide fuel cell (SOFC) is a potential energy conversion technology with high efficiency and high fuel impurity tolerance. Its electrolyte layer is a crucial component and a novel ceria-carbonate electrolyte ceramic membrane has been developed for the intermediate and low temperature SOFCs (IT-LT SOFCs). The ceria-carbonate electrolyte can be produced by either a two-steps process which produces microscale particles or a one-step process which produces nanoscale materials. The ceria-carbonate composite ceramic membrane facilitates both of the oxide ion and proton conductions thus this material has a potential to raise the multi-ions transportation and improve performance of IT-LT SOFCs.
