<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell of which electrode peeling by a heat cycle at a long-time operation is prevented, and capable of sustaining a stable power generation performance. <P>SOLUTION: The solid oxide fuel cell includes a power generation cell 5 arranged with a fuel electrode layer 4 and an air electrode layer 3 on both sides of a solid electrolyte layer 2. The fuel electrode layer 4 is structured by a plurality of layers 4a to 4c in a thickness direction, and also, its outermost electrode layer 4c is partitioned into a plurality of electrode patterns 10 forming a hexagonal shape by a groove 10. <P>COPYRIGHT: (C)2008,JPO&INPIT |
