This fuel cell stack (A) has a structure wherein a plurality of single cells (20), each including a membrane-electrode assembly (33) sandwiched by a pair of separators (40, 41), are stacked to form a cell module (M), and a plurality of such cell modules (M) are stacked and sandwiched by a pair of end plates (10, 11) in the stacking direction. Seal plates (P1) for sealing a reactant gas are provided between cell modules (M) and between the cell modules (M) at both ends of the stack and the respective end plates (10, 11), and a voltage measuring terminal (PT) protruding outside the cell is provided on at least one seal plate (P1) among the seal plates. Thus, voltage measurement of portions for which measurement is necessary is possible without the addition of a separate sealing structure. |
