Outline of Final Research Achievements

Ni-YSZ is widely used as a fuel electrode material for solid oxide fuel cells (SOFCs). However, issues such as carbon deposition, sulfur poisoning and coarsening of Ni have been reported. Nickel-free fuel electrodes which do not use nickel have been investigated to improve the long-term durability. For example, perovskite materials such as LaxSr1-xCryMn1-yO3-δ (LSCM) are attracting attention as one of the promising alternative materials for nickel. Not only carbon precipitation and sulfur poisoning resistance, but also stability under the redox cycle has been reported. In this study, we conducted series of experiments on the LSCM-GDC fuel electrodes, and systematically evaluated the design parameters such as sintering temperature, fuel electrode thickness and mixing ratio.

Academic Significance and Societal Importance of the Research Achievements

固体酸化物形燃料電池(SOFC)および電気分解セル(SOEC)は,燃料電池の中でも最も高効率であること,多様な燃料に対応できることから,次世代の電気と化学エネルギー変換において不可欠なデバイスである.その普及に向けて最大の課題とも言えるのが,燃料極に用いられているニッケルの運転中の移動や凝集であり,この課題を克服するために世界的に熾烈な競争が繰り広げられている.本研究は,その鍵となるニッケルフリー燃料極の特性を系統的に明らかにしたものである.
