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.
Claims10
A fuel cell stack structure comprising:
- a plurality of unit cells stacked in a first direction;
- interconnectors which are disposed and stacked at opposite sides of each of the plurality of unit cells so that an upper surface and a lower surface of each of the plurality of unit cells directly contacts one of the interconnectors;
- and
- window frames which support sides of the unit cells at edges of the interconnectors,
- wherein the window frames include at least one first window frame and at least one second window frame having an area larger than an area of the at least one first window frame,
- wherein the at least one second window frame is periodically disposed at a predetermined interval in the first direction, and
- wherein a thickness in the first direction of the at least one second window frame is larger than a thickness in the first direction of the at least one first window frame.
