To enable proper control of the flow rate of fuel gas, air, or cooling water to be supplied to plural fuel battery laminated body with a proper space efficiency and control method with less control quantity.

In the case where fuel gas supplied from a fuel gas supply main pipe 2 is separated, supplied to fuel battery laminated bodies 1a, 1b, and 1c, and discharged from a fuel gas discharge main pipe 5, first orifices 7a, 7b, and 7c for compensating for the difference in the pressure loss caused by the difference in the shapes of fuel gas supply divergent pipes 3a, 3b, and 3c, second orifices 8a, 8b, and 8c for compensating for the difference in the internal pressure loss of the fuel battery laminated bodies 1a, 1b, and 1c, and third orifices 9a, 9b, and 9c for compensating for the difference in the pressure loss caused by the difference in the shapes of the fuel gas discharge divergent pipes 4a, 4b, and 4c are incorporated, and flow rate is adjusted by means of a fuel gas flow rate control valve 6.
