Patent ID: 11309548

Abstract:
A fluid flow plate having first and second fluid flow channels on a fluid flow plate with an active area of fluid flow fields having one or more arrays of fluid transfer points (301, 302, 303) disposed along an edge of the flow field for communicating fluid into or out of flow channels. A first and second distribution gallery (15, 16, 21) with peripheral edge portions bounded by the arrays including at least one pair of inlets in external edges of the fluid flow plate and wherein the first fluid distribution gallery is shaped such that the combined lengths of the first-gallery second peripheral edge portions are longer than the first-gallery first peripheral edge portion, and wherein the internal edges of the flow plate comprise edges of a hole, aperture, or port passing through the flow plate, and the external edges of the flow plate comprise an outer peripheral edge of the plate. The edges each may comprise a castellated structure (31, 32, 34).
