| Outline of Final Research Achievements |
Solid oxide fuel cell (SOFC) is very attractive due to high energy conversion efficiency and low environmental load. It is important to improve the bondability of electrode and electrolyte for realization of a high power generation efficiency of the fuel cell. The purpose of this study is an establishment of fabrication technique of Ni-cermet consisting of Ni and electrolyte materials and a characterization in the operating environment of SOFC. The cermet samples were prepared by changing the sintering temperature and the mixing ratio of NiO and electrolyte, such as BCO andBZO proton conductors. After heat-treatment in hydrogen atmosphere, Ni-BaZr0.91Y0.08Co0.01O3-δ cermet preferably showed higher than 30% open pore ratio for electrode reaction. Behavior of the electrical conductivity of these samples thus processed was desirable for the fuel electrode. The performance of the conductivity of Ni-cermet obtained this experiment was extremely enhanced in comparison to previous work.
