PROBLEM TO BE SOLVED: To restrain a drop of performance of a fuel cell caused by dispersion of a gas quantity supplied to a passage in each unit cell to prevent gas passage inside the fuel cell from being blocked by condensed water. SOLUTION: A gas distributor 20 is provided with a disk part 24 having a hole part 23, and a rotary shutter 22 having a blade part 25. When oxidizing gas is fed from a prescribed oxidizing gas feeder through an oxidizing gas passage 70, the oxidizing gas abuts to the blade part 25 to rotate the disk part 24. The oxidizing gas is introduced into branched gas 71-74 after passing through a space arranged between the disk part 24 and the oxidizing gas passage 70 and the hole part 23 to be fed to each fuel cell stack for constituting a fuel cell through the branched gas passage. At this point, mote quantity of oxidizing is fed in the branched gas passage with its cross section overlapped to the hole part 23 than that in the other branched gas passage so as to blow away condensed water collected in the oxidizing gas passage of the fuel cell stack corresponding to it to be removed. |
