| Outline of Final Research Achievements |
An anode-supported honeycomb solid oxide fuel cell with nine flow channels (3x3) was prepared by applying an electrolyte and a cathode layers on the anode support in house and fired. When the ratio of the number of the anode flow channels to the number of the cathode channels was changed, an increase in volumetric power density was observed owing to an increase in the number of the cathode flow channels. In addition, the current-voltage characteristics showed a promising volumetric power density compared with conventional electrolyte-supported honeycomb SOFC. This is probably because fuel diffusion is promoted three-dimensionally in the porous honeycomb anode support. From three-dimensional hydrogen partial pressure and current distribution analyses by applying the finite element method, three-dimensional fuel diffusion behavior due to the flow channel arrangement was shown, clarifying essential design factors.
