Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel gas humidifying device for a fuel cell bipolar plate installed in the middle stage of a fuel cell positive electrode side gas flow path, improving performance of the fuel cell by overcoming lack of humidity contained in the fuel gas at the middle and latter stage of the fuel gas flow path. SOLUTION: The fuel gas humidifying device for the fuel cell bipolar plate is designed so as to directly introduce humidifying water in the fuel gas flow path of the fuel cell bipolar plate through a water absorbing material stuck to a mutual communication flow path installed at the middle stage of the fuel gas flow path and covering thereof, to make the fuel gas in the fuel gas flow path obtain sufficient moisture, to increase a humidity content of a proton exchange film, and to improve efficiency of the fuel cell.
