| Outline of Final Research Achievements |
The ability of the infiltration technique to control microstructures of solid oxide fuel cell anodes has been investigated to achieve desirable porous microstructures that can enhance anode performance. Characteristics of the infiltrated Ni-YSZ anodes were investigated using electrochemical and 3D microstructural analysis. The anodes fabricated by infiltration based on thermal decomposition and electrodeposition exhibited superior performance than the conventional anodes. This can be attributed to the increased active reaction site density owing to the smaller metal Ni particles. On the other hand, the anodes fabricated by infiltration based on electroless deposition did not show sufficient electrochemical activity. This is due to the inhomogeneous distribution of the deposited Ni particles, which indicates controlling deposition rate is important to achieve desirable anode microstructures.
