Abstract
In a fuel cell stack that is made by stacking unit cells in alternation with separators, lower edges of collector members that are in contact with oxygen electrodes of the unit cells project downward, providing projecting portions that project below lower edges of frames. Water-repellent regions are provided on lower edges of the projecting portions, facilitating shedding of water from the projecting portions.
