Abstract
A fuel cell stack assembly and method of operating the same are provided. The assembly includes a fuel cell stack column and side baffles disposed on opposing sides of the column. The side baffles and the fuel cell stack may have substantially the same coefficient of thermal expansion at room temperature. The side baffles may have a laminate structure in which one or more channels are formed.
Claims5
A fuel cell stack assembly comprising:
- a fuel cell stack column having an open face and opposing sides extending perpendicular to the open face;
- and
- side baffles disposed on the opposing sides of the column, the side baffles each comprising first, second, and third ceramic baffle plates that are laminated to one another, the second baffle plates being disposed between the first and third baffle plates, and the fuel cell stack column is disposed between the third baffle plates of the side baffles, such that the open face is exposed between the side baffles;
- and
- wherein the second baffle plates comprise air channels configured to cool the column and that extend through the second baffle plates and bypassing the fuel cell stack column in a direction perpendicular to the open face of the fuel cell stack column and perpendicular to a stacking direction of fuel cells of the column.
