Abstract
A fuel cell stack structure in which unit cells are stacked includes first window frames and second window frame. The second window frames each have an area larger than an area of a first window frame and are periodically disposed at a predetermined interval in a direction in which the unit cells are stacked. Heat movement is promoted, a temperature deviation in the fuel cell stack structure is mitigated, and a temperature distribution is uniformized.
