Description
まず、本実施形態において対象とする燃料電池の構造の一例について説明する。図1は、燃料電池100の模式的断面図である。図1を参照して、燃料電池100は、金属支持体10上に、アノード20、電解質層30、およびカソード40がこの順に積層された構造を有している。
実施例1〜4では、アノード20として、1mmの厚さのNi/GDC=60/40wt%複合体を用いた。また、電解質層30として、13μmの厚さのGDC(Ce0.9Gd0.1O2)を用いた。
比較例1では、金属酸化物粉末を焼成することによってカソードを形成した。金属支持体10上にアノード20および電解質層30が積層された積層体を準備した。アノード20として、1mmの厚さのNi/GDC=60/40wt%複合体を用いた。また、電解質層30として、13μmの厚さのGDC(Ce0.9Gd0.1O2)を用いた。
比較例2では、乾燥させたカソード構成材料に対して、さらに、大気中、1100℃で4時間焼付け処理を行った。
実施例1〜4および比較例1,2に対して発電評価を行った。アノードガスとして、H2=200cc/minを用いた。カソードガスとして、Air=400cc/minを用いた。また、運転温度を600℃とした。発電結果を図3および表2に示す。図3は、V−I特性を表したものであり、横軸は電流密度I(A/cm2)を示し、縦軸は発電電圧E(V)を示す。
