PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of being miniaturized by increasing the effective utilization factor of a power generation surface. SOLUTION: In this fuel cell stack, plural unit fuel cells each having an anode-side electrode and a cathode-side electrode formed on both sides of a solid high polymer electrolyte film are stacked through anode-side separators and cathode-side separators 16. In this case, the fuel cell stack is characterized by directly opening the air feeding side of each of the cathode-side separators 16 by eliminating a manifold on the air feeding side, and by forming an outlet- side opening part 34 continuing to the power generation surface of the cathode- side electrode and suctionally structured on each air exhaust side of the cathode- side separators 16. |
