FLOW FIELD PLATE FOR A FUEL CELL

摘要

The present invention discloses a flow field plate (100; 200) for a bipolar plate or bipolar plate assembly of a fuel cell or a fuel cell stack having an electrode facing front side a backside and at least a cooling fluid manifold (102; 202) for supplying cooling fluid to the flow field plate (100; 200) wherein the backside comprises a cooling fluid flow field (1 10; 210) for substantially uniformly distributing the cooling fluid over the flow field plate (100; 200) the flow field plate (100; 200) further comprises a cooling fluid sub manifold (1 12; 212) which is adapted to provide cooling fluid from the cooling fluid manifold (102; 202) to a cooling fluid flow field (210; 1 10) wherein the cooling fluid sub manifold (1 12; 212) is fluidly disconnected from the cooling fluid flow field (1 10; 210) a bipolar plate or bipolar plate assembly comprising a flow field plate as well as a fuel cell or fuel cell stack comprising such a flow field plate and/or bipolar plate or such a bipolar plate assembly.
