Estimating the term…
The present invention provides a solid polymer type 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 a oxidizing agent gas passage formed on the surface thereof are opposed to a fuel electrode or an air electrode and a membrane shape electrolyte 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 oxidizing agent gas passage. In addition, a temperature adjustment means for adjusting the temperature of the fuel or the oxidizing agent 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.
A fuel cell comprising a plurality of stacked cells where separators having respectively a fuel gas passage or a oxidizing agent gas passage formed on the surface thereof are opposed to a fuel electrode or an air electrode and a membrane shape electrolyte is arranged between the fuel electrode and the air electrode, wherein a discharge means is disposed more downstream than the middle of said fuel gas passage or oxidizing agent gas passage.
A fuel cell supplied with fuel and oxidizing agent for power generation, wherein a temperature adjustment means for adjusting the temperature of the fuel or the oxidizing agent is provided at least at one point in the path from the supply inlet to the discharge exit of at least one passage of a fuel electrode side or an air electrode side.
A fuel cell supplied with fuel and oxidizing agent for power generation, wherein a humidity control means for adjusting the moisture of the fuel or the oxidizing agent is provided at least at one point in a path from a supply inlet to a discharge exit of at least one passage of a fuel electrode side or an air electrode side.
