A FLUID FLOW FIELD PLATE AND A SOLID POLYMER ELECTROLYTE FUELCELL

摘要

A fluid flow field plate for use in a solid polymer electrolyte fuel cell includes in a major surface (15) thereof, multiple continuous open-faced fluid flow channels (44) each of which traverses the central area of the plate surface in a serpentine manner. Each of the channels (44) has a fluid inlet (46) at one end and a fluid outlet (48) at the other end which are directly connected to common fluid supply and exhaust openings, (45,47) respectively, defined in the plate.
