固体酸化物形燃料電池電解質へのフィン構造作製方法

抄録

Due to the growing demand for high efficiency power generation system, solid oxide fuel cell (SOFC) is one of the candidate systems because of its high efficiency and fuel flexibility. In order to improve efficiency and reliability of the electrodes, introduction of fin structures in the electrodes are effective. However, fabrication of fin structures on SOFC electrode is challenging, because electrodes are made of hard brittle ceramics which are difficult to manufacture. To solve this issue, a combined process of powder metallurgy and micro molding is developed. The developed combined process enables flexible patterning of hard brittle ceramics material. In addition, micro scale molds can be copied easily, which is suitable for mass-production.
