UNIT CELL HEADER FLOW ENHANCEMENT

摘要

A fluid flow field plate (200) for an electrochemical fuel cell that includes a planar body having a first surface, a second surface. More than one header opening extends between the first surface and the second surface to define a flow path. At least one open flow field Channel with an inlet port and an outlet port is provided in the first surface. Each outlet port is in fluid communication with one of the one header openings. At least one of the outlet port or the inlet port has a baff Ie (230) extending into the flow path.
