Abstract
Official abstract text for this publication.
A fuel cell separator plate includes flake graphite particles having a length along a planar direction and a thickness along a generally perpendicular direction. The flake graphite has an aspect ratio of length to thickness that is less than ten.
First claim
Opening claim text (preview).
We claim: 1 . A fuel cell separator plate, comprising: a polymer; and flake graphite particles having a length along a planar direction and a thickness along a generally perpendicular direction, the flake graphite particles having an aspect ratio of length to thickness that is less than 10. 2 . The fuel cell separator plate of claim 1 , wherein the aspect ratio is less than 7.5. 3 . The fuel cell separator plate of claim 1 , wherein the aspect ratio is between 5.0 and 7.5. 4 . The fuel cell separator plate of claim 1 , wherein the thickness is at least 20 microns. 5 . The fuel cell separator plate of claim 1 , wherein the flake graphite particles are aligned with each other with the length dimension of the particles essentially parallel. 6 . A method of making a fuel cell separator plate, comprising configuring a mixture of flake graphite particles and a polymer into a desired shape of at least a portion of the fuel cell plate, wherein the flake graphite particles have a length along a planar direction and a thickness along a generally perpendicular direction, and the flake graphite particles have an aspect ratio of length to thickness that is less than 10. 7 . The method of claim 6 , wherein the aspect ratio is less than 7.5. 8 . The method of claim 6 , wherein the aspect ratio is between 5.0 and 7.5. 9 . The method of claim 6 , wherein the thickness is at least 20 microns. 10 . The method of claim 6 , wherein the flake graphite particles are aligned with each other with the length dimension of the particles essentially parallel.
