Abstract:
A fuel cell comprising:a laminate of single cells, each of the single cells including an anode, a cathode, and an electrolyte film sandwiched between the anode and the cathode, and the single cells being sequentially stacked on each other through a separator plate provided with fuel flow channels on a first surface facing the anode for supplying a fuel fluid to the anode and oxidant flow channels on a second surface opposite to the first surface and facing the cathode for supplying an oxidant fluid to the cathode, wherein the fuel flow channels are continuous on the first surface from a fuel supply opening to a fuel exhaust opening; and t he oxidant flow channels are continuous on the second surface from an oxidant supply opening to an oxidant exhaust opening, and wherein only one communicating hole is provided at a downstream side with respect to a middle portion of the fuel flow channel of the separator plate, said communicating hole communicating with the fuel flow channel of another separator plate.
