Title: Electrochemical cell

Abstract

A separator plate and a frame member for an electrochemical cell are provided. The separator plate includes a plurality of protrusions extending therefrom to define a flow field. A pair of end features arranged along opposite sides of the flow field, each end feature extending substantially the length of the flow field. A periphery portion is provided having a first set of openings and a second set of openings. Wherein the plurality of protrusions and pair of end features extend from a plane defined by the periphery portion. The frame member includes features for facilitating assembly and reducing the risk of an over constrained condition. The frame member further having ports divided by a bridge member to support the frame member under operating pressures.
