Abstract
A fuel cell stack includes a plurality of power generation cells stacked in a direction of gravity. In a cathode side separator of the power generation cell, an oxygen-containing gas discharge passage is connected to an oxygen-containing gas flow field, and a water guide member is provided for the oxygen-containing gas discharge passage for allowing condensed water to be directly dropped in the direction of gravity along the oxygen-containing gas discharge passage. The water guide member is a plate member protruding into the oxygen-containing gas discharge passage and inclined toward the direction of gravity.
