Abstract
In a solid electrolyte polymer fuel cell system, a fuel cell includes ribs integrally formed with an anode or an anode chamber, ribs integrally formed with a cathode or cathode chamber, and a water distributor. The water distributor may be a beam provided with slits, an electroconductive body, a wick, or a combination of the beam with slits and a hydrophilic body. Fuel gas and water distributed by the water distributor are passed through the ribs of the ribbed anode or ribbed anode chamber to provide sufficient hydrogen ions and water of inclusion with the solid polymer electrolyte. Oxidizer gas and water to be discharged are passed through the ribs of the ribbed cathode or ribbed cathode chamber. Water is discharged efficiently.
