Fluid flow plate for a fuel cell

A method of directing a fluid flow, the method comprising:

• forming a plurality of first fluid flow channels extending across an active area of the flow plate to define a first fluid flow field of the fluid flow plate;
• forming a plurality of second fluid flow channels extending across the active area of the flow plate to define a second fluid flow field of the fluid flow plate;
• providing an array of first fluid transfer points disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels;
• providing an array of second fluid transfer points disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels;
• a first fluid distribution gallery with a first peripheral edge portion bounded by the array of first fluid transfer points having second peripheral edge portion with a first fluid communication edge configured to provide for delivery of fluid into the first fluid distribution gallery and comprising a pair of inlets in the external edges of the fluid flow plate;
• a second fluid distribution gallery with a second fluid communication edge configured to provide for delivery of fluid into the second fluid distribution gallery and comprising at least two portions of the internal edges of the fluid flow plate;
• 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.
