| Outline of Final Research Achievements |
Y-doped BaZrO3 is expected for next generation fuel cells. However, Ni diffusion during co-sintering with the electrode material is now serious problem. We studied various diffusion prevention method. As the results, the promising method is recovering the performance by diffusing Ni out to the grain boundary after co-sintering by reduction treatment, because Ni works as a sintering aid. In addition, it is clarified that 20% of Y-doped BaZrO3, which is often used, does not equilibrate with NiO was obtained.
