A fuel cell including at least a membrane electrode assembly (MEA), a pipe, a pump and a linkage arrangement is provided. The MEA includes an anode layer, a cathode layer and an electrolyte layer disposed between the anode layer and the cathode layer. The pump is adapted to drive a fluid flowing in the pipe to provide fuel for the anode layer. The linkage arrangement includes a first blade, at least a second blade and a connecting element. The first blade is disposed inside the pipe and located on a flowing path of the fluid, and the fluid is adapted to drive the first blade to rotate. The second blade is disposed outside the pipe, and the connecting element is adapted to connect the first blade and the second blade so that the first blade drives the second blade to rotate to bring air to flow through the cathode layer.
