Abstract: Disclosed is a fuel cell with improved thermal distribution in a stack including two more unit cells stacked therein. The fuel cell includes a stack including the two more unit cells and separators each having manifolds formed through four sides thereof, a first chamber having an internal space so as to receive air and fuel from the outside and to transfer the air and fuel to a second chamber and so as to receive the air and fuel discharged from the stack and to discharge the air and fuel to the outside, a second chamber having an internal space so as to receive the air and fuel from the first chamber and to transfer the air and fuel to the stack, and a connecting part connecting the first chamber to the second chamber so as to allow the air and fuel to flow to the second chamber from the first chamber.
