Abstract
Novel fluid flow field plates for use in a solid polymer electrolyte fuel cell include in a major surface thereof, multiple continuous open-faced fluid flow channels each of which traverses the central area of the plate surface in a serpentine manner. Each of the channels has a fluid inlet at one end and a fluid outlet at the other end which are directly connected to common fluid supply and exhaust openings, respectively, defined in the plate.
