Abstract

PURPOSE:To absorb and store a moving electrolyte for a long time to prevent deterioration in cell performance caused by movement of electrolyte by storing a larger amount of electrolyte in a cathode end cell and an anode end cell than an intermediate cell in a cell stack. CONSTITUTION:A larger amount of electrolyte is stored in a cathode end cell and an anode end cell than an intermediate cell in a cell stack. A fuel gas passage 16 and a spacer 17 are made of porous bodies, and can store a large amount of electrolyte. The cathode end cell can supply the electrolyte toward the anode end cell for long hours. A fuel gas passage 20 and a spacer 21 are also made of porous bodies. The electrolyte amount in the anode end cell in the initial stage of operation is smaller than that in the cathode end cell. The anode end cell absorbs and stores the electrolyte moved from the cathode end cell for long hours. Deterioration in cell performance caused by movement of electrolyte can be prevented.
