In addition, if the thicknesses of the latching protrusions in the first direction are the same and the widths of the first slits in the first direction are the same, the separators may be regularly or equally spaced apart from each other in the first direction. Thus, the stacking tolerance of the separators in the first direction may be eliminated. As such, the separators may be in a good aligned state so that receiving recesses defining a receiving space may be aligned without positional shifts. Thereby, the cell-monitoring connector may be easily assembled to the separators. Further, when the cell-monitoring connector is mounted to the separators, the inner edge of each separator, which is contiguous with the first, second and third sides of the receiving recess, may be prevented from being bent (deformed) or damaged.

In addition, when the fuel cell according to the embodiment is installed in a vehicle, if the cell-monitoring connector shakes in the third direction due to vibration and impact caused by travel of the vehicle, it is not possible to accurately measure the voltage value. That is, the measured voltage value changes unstably, and thus the reliability of the measured value is lowered. The cell-monitoring connector may, in the worst case, be separated from the separators. However, according to the embodiment, the cell-monitoring connector is prevented from being shifted in the third direction using a third gasket, which serves as a shift-preventing part, and a shift-preventing groove, thus preventing the above problem.

In addition, according to an exemplary embodiment of the present disclosure, since adjacent separators are alternately fitted into second slits of two different sections, the interval between adjacent separators in the first direction may be reduced.
