PROBLEM TO BE SOLVED: To provide a fuel battery stack that makes it difficult for water and dust to accumulate on a gas permeable membrane at a ventilation hole of a case.SOLUTION: The fuel cell stack includes a fuel cell main body including a stacked body 11 formed by stacking a plurality of fuel cell single cells in the stacking direction S, and a case having four side walls and at least one opening surrounding the fuel cell main body along the stacking direction and accommodating the fuel cell main body while compressing it. The four side walls include an upper side wall 22a1 disposed on the upper side when the fuel cell stack is mounted on the moving body. The case is provided with a ventilation part 4 formed on the upper side wall. The ventilation part includes a through hole 40 formed in the upper side wall and communicating the inside and the outside of the case, a through hole 40 formed by the gas permeable film 45 and extending from the periphery of the through hole to the outside of the case so that the gas permeable film is self- A tubular wall portion 41 provided, and a lid portion 42 attached to an outer end of the tubular wall portion.SELECTED DRAWING: Figure 5 |
