Abstract:
A fuel cell (3) includes interconnectors (hereinafter, IC) (12, 13), a cell body (20) disposed between the ICs and including an air electrode (14) and a fuel electrode (15) on both surfaces of an electrolyte (2), and current collecting members (18, 19) disposed between at least one of the electrodes (14, 15) and the ICs. The current collecting members (19) include connector contact portions (19a) in contact with the IC (13), cell body contact portions (19b) in contact with the cell body (20), and connecting portions (19c) that are bent approximately 180 degrees and connect both the contact portions. The connector contact portions include asperities (19e) on outside surfaces of the connector contact portions on the side where the connector contact portions are in contact with the IC 13, and a spacer (58) is disposed between the connector contact portions and the cell body contact portions.
