Abstract
A more compact humidifying apparatus for a fuel cell can be implemented. In the present invention, hydrogen humidifying modules 30A and 30B are disposed so as to be separated vertically on the front surface side of the humidifying unit 20, the air humidifying modules 30C and 30D are disposed separated vertically on the back side surface thereof, and the air humidifying modules 30E is disposed at the center, surrounded by the humidifying modules 30A, 30B, 30C, and 30D. The axis direction of all of the humidifying modules 30A to 30E are disposed so as to be parallel to each other, only the hydrogen humidifying module 30A is disposed so that its position is shifted to the left (the longitudinal direction) of the axial direction of the other humidifying modules 30A to 30E, and the air off gas discharge pipes 43 of the air humidifying modules 30C to 30E are disposed in the space formed by this shift.
