A fuel cell stack according to an exemplary embodiment of the present invention includes a plurality of unit cells that generate electrical energy by a reaction of fuel and oxygen, and the unit cells are arranged in series to form an aggregate structure of the unit cells. And a cooling passage formed between the fuel cell body and a unit cell corresponding to a central portion of the fuel cell body, and passing through a cooling medium, wherein each unit cell includes a membrane electrode assembly (MEA). The separator is arranged to be in close contact with both sides thereof, and the cooling passage is formed between the separators which are in close contact with each other with respect to neighboring unit cells.n n n n Fuel Cell, Body, Stack, Unit Cell, Cooling Path, Single Sided, Double Sided |
