Abstract
Official abstract text for this publication.
A plate for a fuel cell includes a first plate body defining a first flow field channel in a first surface thereof. The first flow field channel has a cross-sectional area that varies as a function of depth from the first surface of the plate body toward an opposed second surface. The cross-sectional area can increase and/or decrease from the first surface toward the opposed second surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A plate for a fuel cell comprising: a first plate body defining a first flow field channel in a first surface thereof, wherein the first flow field channel has a cross-sectional area that varies as a function of depth from the first surface of the plate body toward an opposed second surface; and a second plate body defining a second flow field channel in a first surface thereof, wherein the second flow field channel has a cross-sectional area that varies as a function of depth from the first surface of the second plate body toward an opposed second surface, wherein the first surface of the second plate body is adjacent the first surface of the first plate body such that the first flow field channel and the second flow field channel define a continuous flow field path. 2. The plate of claim 1 , wherein the cross-sectional area of the first flow field channel increases from the first surface toward the opposed second surface. 3. The plate of claim 1 , wherein the cross-sectional area of the first flow field channel decreases from the first surface toward the opposed second surface. 4. The plate of claim 1 , wherein the cross-sectional area of the second flow field channel increases from the first surface toward the opposed second surface. 5. The plate of claim 1 , wherein the cross-sectional area of the second flow field channel decreases from the first surface toward the opposed second surface. 6. The plate of claim 1 , wherein the cross-sectional area of the flow field path perpendicular to the first surface of the first plate body and the first surface of the second plate body is I-shaped. 7. The plate of claim 6 , wherein a width of a first end of the flow field path is less than a width of a second end.
