FLOW FIELD PLATE FOR A FUEL CELL

摘要

A flow field plate for a bipolar plate or bipolar plate assembly of a fuel cell or a fuel cell stack has an electrode facing front side, a backside and at least a cooling fluid manifold for supplying cooling fluid to the flow field plate. The backside includes a cooling fluid flow field for substantially uniformly distributing the cooling fluid over the flow field, plate. The flow field plate further includes a cooling fluid sub-manifold which is adapted to provide cooling fluid from the cooling fluid manifold to a cooling fluid flow field. The cooling fluid sub-manifold is fluidly disconnected from the cooling fluid flow field, a bipolar plate or bipolar plate assembly including a flow field plate, as well as a fuel cell or fuel cell stack including such a flow field plate and/or bipolar plate or such a bipolar plate assembly.
