PROBLEM TO BE SOLVED: To provide a fuel cell unit cell that maintains favorable electrical connectivity even after a long period of use, and to provide a fuel cell stack.SOLUTION: A fuel cell unit cell 3 includes: a cell main body 20 that is positioned between a pair of interconnectors (hereinafter referred to as ICs) 12 and 13 and that has electrodes 14 and 15 formed on two respective sides of an electrolyte 2; and a collector member 190 that electrically connects the electrode 15 and the IC 13. The collector member 190 has: a connector contact portion 190a that is in contact with the IC 13; a cell main body contact portion 190b that is in contact with the electrode 15 of the cell main body 20; and a connecting portion 190c that connects the connector contact portion 190a and the cell main body contact portion 190b. The connector contact portion 190a, the cell main body contact portion 190b, and the connecting portion 190c are formed continuously. The collector member 190 also has a spacer 580 that is arranged between the connector contact portion 190a and the cell main body contact portion 190b. The collector member 190 and the spacer 580 have elasticity in a direction in which a gap between the cell main body 20 and the IC 13 widens. The spacer 580 has a greater amount of elasticity than the collector member 190. |
