Abstract
Provided is a fuel cell stack including a plurality of stacked cells each having separators, in which the corrosion (dissolution) of the base material of each separator used for the end cell, which includes one or more cells located at the positive-side end of the fuel cell stack, can be prevented at low cost and without the productivity decreased. In the fuel cell stack including a plurality of stacked cells each having separators, the base material of each of the separators used for the end cell located at the positive-side end of the fuel cell stack and the base material of each of the separators used for the other cells are different metallic materials, and the base material (e.g., Ti) of each of the separators used for the end cell has higher corrosion resistance than the base material (e.g., SUS) of each of the separators used for the other cells.
