A terminal plate, an insulating plate, and an end plate are stacked on a stack body. The terminal plate has current collectors at least at lower portions of an oxygen-containing gas supply passage, a coolant supply passage, a fuel gas discharge passage, a fuel gas supply passage, a coolant discharge passage, and an oxygen-containing gas discharge passage. The current collectors contact the water generated in the reaction or a coolant for collecting electricity.
