Outline of Final Research Achievements

Porous film forming technique was developed to reduce the operating temperature for SOFC. Using the technique, porous anode film can be made from porous fine particles synthesized by the advanced spray pyrolysis method. The electrochemical properties of SOFC such as the power density and the reaction resistance were improved by the synthesis condition of the particles and the formation condition of the film.

Academic Significance and Societal Importance of the Research Achievements

本研究の対象であるセラミック微粒子およびセラミック薄膜は、燃料電池だけでなく、全固体電池や触媒、ガス分離膜などにも使われる材料である。セラミック膜の作製には高温下での焼結が必要であるが、高温下では細孔が塞がり多孔質構造が失われる。本研究の技術を利用すれば、他の材料でも多孔質構造を維持した膜の成形が期待される。
