Abstract
Official abstract text for this publication.
A fuel cell comprises a bipolar plate having a cationic polymer layer and a conductive and hydrophilic surface layer disposed on at least a portion of its exterior area. The surface layer comprises a conductive carbon material having a hydrophilic organic group ionically attached to its surface. A process of producing a bipolar plate and a fuel cell is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A product comprising a fuel cell bipolar plate having an external surface, a cationic polymer layer over the external surface, a conductive and hydrophilic surface layer disposed over at least a portion of the external surface; wherein said conductive and hydrophilic surface layer comprises a conductive carbon material having a hydrophilic organic group, the conductive carbon material ionically attached to one of the cationic polymer layer wherein the cationi…
