Abstract
Disclosed is a fuel cell stack comprising fuel cell units and first and second separators which are alternately stacked with each other. Wedge members are integrally inserted, over the plurality of fuel cell units, into communication holes of a fuel gas supply passage, an oxygen-containing gas supply passage, and a cooling water supply passage, as well as a fuel gas discharge passage, an oxygen-containing gas discharge passage, and a cooling water discharge passage. A fluid is uniformly delivered to each of the fuel cell units by the aid of the wedge members. Accordingly, the fluid of any one of a fuel gas, an oxygen-containing gas, and a cooling medium is uniformly delivered to each of the fuel cell units. Further, it is possible to simplify the arrangement of the fuel cell stack.
