A humidification system for a fuel cell includes a humidifier having a bundled plurality of tube type hollow thread members made of a water permeable membrane. The humidifier transfers a water content contained in a discharge gas, which is emitted from a fuel cell, to a supply gas, which is supplied to the fuel cell, when one of the discharge gas and the supply gas is passed through the inside of the tube type hollow thread members and the other one of the discharge gas and the supply gas is passed through between the tube type hollow thread members. Manometers P1, P2, P3, and P4 detect a difference in pressure of the supply gas and the discharge gas, respectively, between an upper stream side and a down stream side of the humidifier. A determination unit determines a generation of clogging in the humidifier based on detection signals from the manometers.
