Abstract: PURPOSE:To maintain electrolyte in a sufficient water holding condition, and stabilize output of a fuel cell by forming a fuel or oxidating agent flowing passage as a bending passage continuing at least by a single turnaround and a half, and arranging it in a plurality. CONSTITUTION:Fuel or an oxidating agent supplied from outside of a fuel cell body is introduced to an inlet side fluid manifold 11 through a fluid introducing hole 9, and distributively flows to a fluid passage groove 15 as a passage arranged on the reverse of a separator 8 through an inlet side fluid communicating hole 13. In this case, the groove 15 is once reversed in the vicinity of an outlet side fluid manifold 12, and is again introduced to the vicinity of the manifold 11, and is further once again reversed. Thereby, as a result, after a passage continuing by a single turnaround and a half is formed, it is directly connected to the manifold 12. Thereby, since a humidifying moisture shortage situation of electrolyte particularly on the downstream part side of the fuel flowing groove 15 is compensated with humidifying moisture from an upstream part of the groove 15, the electrolyte can be uniformly put in a sufficient water holding condition, so that output of a fuel cell can be stabilized.
