Abstract
A fuel cell includes a first separator and a second separator. A second protrusion is formed on a first sealing portion of the first separator. A concave portion is formed in a second sealing portion of the second separator. When fuel cells are stacked together sequentially in the vertical direction without displacing relative to one another, the center of the second protrusion and the center of the concave portion are aligned with each other. Even if the fuel cells are displaced while being stacked together, the upper fuel cell in the vertical direction is moved to decrease the distance between the center of the second protrusion and the center of the corresponding concave portion.
