| Outline of Final Research Achievements |
A method to control the reaction rate in a reforming domain for getting a desired temperature distribution was established by using the paper-structured catalyst (PSC) technology. Aiming at the development of a compact and highly-efficient solid oxide fuel cell (SOFC), one-cell module (single cell integrated with plate-type reformer) was designed and developed. PSC segments with uniform or graded arrays were packed in the reformer, and power generation tests of the one-cell module were conducted by feeding simulated biogas at the furnace temperature of 800oC and 0.2 A cm-2. Graded PSC arrays leading to the uniform temperature distribution resulted in the twofold durability of the module compared to the uniform PSC arrays which caused strong temperature gradient at the fuel inlet side. This achievement was applied to the two-cell module (PSC-packed plate-type reformer sandwiched by two cells), and power generation efficiency of 41% was recorded at 0.8 A cm-2 (Fuel utilization 70%).
