PROBLEM TO BE SOLVED: To operate a fuel cell while regulating the amount of gas supply thereto responding to the load of the fuel cell in a gas supply system using an ejector. SOLUTION: A fuel cell system is used. The system comprises a fuel cell 1 for generating power, gas humidifying parts 4 and 5 that contain water, circulation pipes 20-1 to 3 and 21-1 to 3 that connect the gas humidifying parts 4 and 5 and circulate the water, water circulation pumps 8 and 9 that circulate the water in the circulation pipes 20-1 to 3 and 21-1 to 3, ejectors 6 and 7 that are connected in the way of the circulation pipes 20-1 to 3 and 21-1 to 3 for drawing the gas in the fuel cell 1 to the circulation pipes 20-1 to 3 and 21-1 to 3 from the fuel cell 1 by the flow of the water, and a regulation part 31 that regulates the rotation number of the water circulation pumps 8 and 9 based on the output current of the fuel cell 1. |
