Research Abstract

これまで、Ni1-x MgxO(x=o,o.1)を燃料極材料に適用し、模擬バイオガスを供給して200時間以上に渡る固体酸化物形燃料電池(SOFC)の安定作動を確認している。当該研究では、バイオガス直接供給SOFCの性能向上を目的とし、Ni1-xMgxO-ScSZ(x=0〜0.4)のキャラクタリゼーションを行った。模擬バイオガス(CH4/CO2=1.5)供給時の、Ni1-x MgxO-ScSZアノード上で生じる改質反応の速度は、バイオガス供給初期は、xと共に直線的に増加した。この触媒能の向上は、xと共に微細なNi粒子の析出が顕著になるためであるが、高い活性を維持させるためには、x=0.4のMgO添加が必要であることが明らかとなった。Ni1-xMgxO-ScSZ(x=0〜0.4)を成型、焼成し、還元処理後、四端子法により導電率測定を行ったところ、x≧0.15では絶縁性を示し、導電性を示すx=0および0.1の場合のみ、電極に直接適用可能であることが明らかとなった。x≧0.15を電極として適用可能にするには導電性の付与が必要である。
