Abstract
The present invention provides a polymer electrolyte fuel cell capable of eliminating condensate water, and preventing flooding due to an excessively humidified electrode by a simple structure and easy processing composition. A fuel cell comprising a plurality of stacked cells where separators having respectively a fuel gas passage or an oxidant gas passage formed on the surface thereof are opposed to a fuel electrode or an air electrode and an electrolyte membrane is arranged between the fuel electrode and the air electrode, in which a drainage means is disposed downstream the middle of the fuel gas passage or oxidant gas passage. In addition, a temperature adjustment means for adjusting the temperature of the fuel or the oxidant is provided at least at one point in the path from the supply inlet to the discharge exit of at least one passage of fuel electrode side or the air electrode side.
