Patent ID: 8247134

Claim:
A fuel cell comprising: a separator having two sides, the separator being adapted to allow a fuel to flow to both sides of the separator; anode portions disposed at both sides of the separator so that the separator is interposed between the anode portions along a stacking direction, each of the anode portions comprising a path member having channels forming a flowpath therein for the fuel to flow along a plane of the anode portions, the plane of the anode portions being perpendicular to the stacking direction; membrane-electrode assemblies disposed in close contact with the anode portions; and cathode portions disposed in close contact with the membrane-electrode assemblies, the cathode portions being adapted to allow air to circulate through the cathode portions, wherein the separator comprises a first fuel pathway configured to supply the fuel to the anode portions and a second fuel pathway separated from the first fuel pathway and configured to discharge the fuel from the anode portions.
