Development of Ceramics and Glass Materials for Solid Oxide Fuel Cell and Oxygen Permeable Membrane
Yosuke Takahashi, Noritaki Co., Ltd., Japan
Mixed-ion conducting ceramics of perovskite oxides and glass sealing materials have been developed and studied. The purposes of these studies were to use the materials as cathode and sealing materials for solid oxide fuel cells (SOFCs) and as oxygen-permeable membranes. Some of these materials for SOFCs are mass-produced and industrialized. SOFCs have been actively developed as a next-generation power source because of their high power generation efficiency.
In Japan, “Energy carriers” has been launched as a theme of “Cross-ministerial Strategic Innovation Promotion Program (SIP)” since 2014. “Energy carriers” are materials for storing or transporting energy. In SIP, ammonia has been studied as a carbon-free energy carrier. In this work, ammonia was experimented to use as a fuel for solid oxide fuel cells (SOFC). As a result, with the SOFC which can directly use ammonia, the world’s largest experiment of power generation has successfully demonstrated.
