ABSTRACT:
Disclosed is an electrochemical cell having a structure of wetting diaphragm made of a solid polymer electrolyte in which at least a narrow path for supplying water to the solid polymer electrolyte is formed. According to the electrochemical cell of this invention, the elevation of performance of the above cell is contemplated by increasing ionic conductivity and excluding burdensome control of water vapor in a reaction gas by means of adding water in the solid polymer electrolyte through the narrow path.
