Outline of Final Research Achievements

Preparation of Ni-based cermet anodes, which is effective for the direct oxidation of methane in solid oxide fuel cells, and their electrochemical characteristics have been investigated. The anode performance was evaluated with a combination of ceria-based electrolyte and zirconia-based electrolyte materials. The results of electrochemical measurements and microstructural characterization revealed that the enhancement of the direct oxidation of methane was caused by the optimum modification of microstructure in the cermet anode. The adsorptive abilities of several anode particles for CH4,CO, and H2 were found to affect the anodic oxidation of methane.
