Abstract:
1. A fuel cell comprising: power generation bodies each having a first electrode and a second electrode; and a plurality of separators stacked alternately with the power generation bodies so as to constitute the fuel cell, each separator including: a first surface that faces the first electrode of one of the power generation bodies; a second surface that faces the second electrode of another one of the power generation bodies; at least one first reactant gas discharge channel that is provided for discharging a first reactant gas from the first electrode facing the first surface and that extends in the separator and has, at an end of the first reactant gas channel, a discharge opening portion that is opened in the first surface; and a second reactant gas supply channel that is provided for supplying a second reactant gas to the second electrode facing the second surface and that extends in the separator and has, at an end of the second reactant gas channel, a supply opening portion that is opened in the second surface, wherein at least a portion of the discharge opening portion of the at least one first reactant gas discharge channel and at least a portion of the supply opening portion of the second reactant gas supply channel are disposed, in the separator, along substantially an entire length of a first side of a generally rectangular power generation region that faces the power generation bodies when the separator is stacked with the power generation bodies, and are positioned parallel to each other wherein the discharge opening portion and the supply opening portion are rectangular shaped longitudinal slits each having two equally sized long sides and two equally sized short sides, and the long sides being parallel to sides of the power generation region.
