EMBOSSED FLUID FLOW FIELD PLATE FOR ELECTROCHEMICAL FUEL CELLS

摘要

An embossed fluid flow field plate (100) for electrochemical cells comprises a compressible, electrically conductive sheet (101). The sheet has two oppositely facing major surfaces. At least one of the major surfaces (102) has an embossed surface which has a fluid inlet (116) formed therein. The embossed surface has at least one open-faced channel embossed therein extending from the fluid inlet for conducting pressurized fluid introduced at the fluid inlet. The compressible, electrically conductive sheet preferably comprises graphite foil.
