ABSTRACT:
Disclosed is a structure for wetting a diaphragm of a solid polymer electrolyte fuel cell in which one or more hollow paths are provided in or on the diaphragm for supplying water to the solid polymer electrolyte.
According to the structure of this invention, the elevation of performances of the above cell is achieved by wetting the diaphragm at a desired level. Since the water can be supplied through the hollow paths with substantially no resistance, the amount to be supplied can be freely controlled.
