Summary:PROBLEM TO BE SOLVED: To provide a humidification system of a fuel cell capable of determining whether a dew-point sensor is faulty, without interruption of a performance test or the like of the fuel cell. SOLUTION: The system comprises a failure determination part 5p determining whether dew-point sensors M1, M2 are properly working based on measured dew points measured by the dew-point sensors M1, M2 and predicted dew points or preset dew points in case a value of an environment parameter is smaller than a given volume, and a control switching part 5g for switching over for operation from a feedback dew-point control part 5i to a feed-forward dew-point control parts 5j, in case the failure determination part 5p determines that the dew-point sensors M1, M2 are not properly working during operation of the feedback dew-point control part 5i.
