Abstract
One end of an air passage () facing a cathode (B) of a fuel cell () forming a fuel cell stack () is connected to a first manifold (A), and the other end is connected to a second manifold (B). A water-absorbing material () is disposed at a position in contact with an air flow in the first manifold (A) and second manifold (B). The air is made to circulate according to a humidity state by changing over between a first air flow direction wherein air flows from the first manifold (A) to the second manifold (B) via the air passage (), and a second air flow direction wherein air flows from the second manifold (B) to the first manifold (A) via the air passage (), so a membrane electrolyte is efficiently humidified.
