1. An air-cooled fuel cell comprising:
a cell stack;
an air inlet manifold configured to allow air to flow into the cell stack therethrough;
an air outlet manifold configured to allow the air to flow out of the cell stack therethrough; and
a manifold opening/closing controller disposed at the air inlet manifold or the air outlet manifold to allow or interrupt inflow or outflow of the air based on an operation state of the cell stack
wherein the manifold opening/closing controller comprises:
a first opening/closing controller disposed at the air inlet manifold; and
a second opening/closing controller disposed at the air outlet manifold, and
wherein each of the first opening/closing controller and the second opening/closing controller comprises:
a driving unit configured to be rotated by a motor;
a power transmission unit configured to transmit rotational force of the driving unit as power; and
a valve seat configured to be moved upwards and downwards by the power transmitted from the power transmission unit to open or close the air inlet manifold or the air outlet manifold.
