PROBLEM TO BE SOLVED: To provide a fuel cell system having high reliability and capable of maintaining a stabilized operating condition while securely preventing drying of a solid high molecular electrolyte film without hindering miniaturization of the system. SOLUTION: A temperature sensor 19 for detecting the temperature is fitted to a fuel cell body 1. A temperature and humidity exchanger 2 for exchanging temperature and humidity between the non-reacting air and the reacted air is provided, and an air supply fan 5 is fitted to the temperature and humidity exchanger 2 through a non-reacting air supply pipe 6. A control unit 8 for controlling the air supply fan 5 on the basis of the detected temperature is connected to the temperature sensor 19. |
