| Outline of Final Research Achievements |
In order to improve the electric power of microbial fuel cell (MFC), graphite was used as conductivity material. Powder graphite and granule graphite were used. And ratios of the graphite were set to five values between 0% and 20%. And also we conducted experiments in order to find the best interval time for the repeat of discharge and charge of MFC. In addition, a mathematical model was made for simulation of the reaction. Then, the best interval time was estimated. As a result, 10% of powder graphite was the best ratio for the electric power. And also, the interval time of the repeat was less than 60 s, it was 1.2 times higher than continuous discharge. Furthermore, the model simulation shows that the best time is less than 15 s.

| Academic Significance and Societal Importance of the Research Achievements |
微生物燃料電池の課題である発電力が微小であり，不安定ということを解決するために，土壌を使用することは，実際の廃水処理としても可能である。また，内部抵抗が増加するというデメリットを改善するために，導電物質の添加の有効性を示した。また，新たな材料は使うことなく，放電－充電を繰り返すという使用方法を工夫だけで，電力が増加することを示した。さらに，最適な条件を，数式モデルを作成して検討できることも示したことにより，実処理への適用の判断材料になると考えられる。
