摘要： A method fabricates fluid flow field plates that are suitable for use in an electrochemical fuel cell assembly. Pursuant to the method, a fluid flow field channel region such as, for example, substantially straight, parallel fluid flow field channels, is roller embossed in a sheet of compressible, electrically conductive material such as, for example, expanded graphite sheet material. A fluid distribution region such as, for example, a region containing manifold openings and supply channels, is then reciprocally embossed in the sheet material. A sheet pre-impregnated with a curable polymeric composition, such as pre-impregnated expanded graphite, can be employed, with the curing step being performed after the roller embossing and reciprocal embossing steps.

摘要： A flow field plate assembly for an electrochemical fuel cell comprises two flow field plates, each of which has channels formed on an inner surface of the plate. The plates are alignable with and engage each other such that their cooperating inner surfaces form at least one inner coolant fluid channel. The coolant channel has an essentially constant cross-sectional perimeter along its length, which is defined by the perimeters of the channels of the two plates and their difference in width at the cooperating plate surfaces. Additionally, a flow field plate assembly, which comprises a corrugated flow field plate and a staggered flow field plate, is structurally stronger under compressive load during the fuel cell operation.
