| Outline of Final Research Achievements |
Depletion of fuel and oxygen in a solid oxide fuel cell greatly affects the cell performance, giving rise to current distribution in a cell. The current distribution affects the cell thermo-mechanical durability since it leads to temperature distribution in the cell. The current distribution also prevents effective use of whole electrode area in the cell geometry. Oxidation of nickel catalyst is caused as well. In particular, syngas fuel leads to the degradation by carbon deposition. Thus we clarify longitudinal current distributions for syngas fuel by electrode-segmented cells. Spacial surface temperature measurements give internal reforming reaction rate distribution along the cell.
