Abstract
A fuel cell system includes a first fluid flow plate including a first plurality of first channels for flow of an oxidant or a fuel. The plurality of first channel has first channel cross-sectional flow areas. A second fluid flow plate includes a second plurality of second channels for flow of an oxidant or a fuel. The plurality of second channels has second channel cross-sectional flow areas. A membrane electrode assembly is located between the first plate and the second plate. The first flow plate includes a passage for a flow of a fluid entirely on a seam side of the first flow plate as the first plurality of first channels. The passage has a cross-sectional area for flow of the fluid smaller than the first channel cross-sectional flow area.
