▎ 摘　　要

NOVELTY - The flow field comprises a graphene foam and sheet. A film is interposed between a membrane-electrode assembly and a bipolar plate, when manufacturing the fuel cell. The graphene foam is compressed graphene foam. The fuel cell is a polymer electrolyte membrane fuel cell. USE - Flow field for distributing reactants, removing generated water and managing generated heat in a fuel cell (Claimed). ADVANTAGE - The flow field comprises a graphene foam and sheet, where film is interposed between a membrane-electrode assembly and a bipolar plate and graphene foam is compressed graphene foam, and thus enables to provide excellent performance and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a fuel cell has an inlet line. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a bipolar plate.
