Abstract
The invention disclosed is a novel fluid flow field plate for use in a solid polymer electrolyte fuel cell. The plate includes in a major surface thereof, a continuous open-faced fluid flow channel which traverses the central area of the plate surface in a serpentine manner. The channel has a fluid inlet at one end for receiving a reactant gas and a fluid exhaust at the other end for removing excess reactant gas and reaction products from the cell.
