Abstract
Official abstract text for this publication.
A process including coating a fuel cell component with an aqueous solution including a polyelectrolyte polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A process comprising: providing a bipolar plate having a surface that delineates a plurality of lands and channels which define a gas flow field; applying an aqueous solution comprising a polyelectrolyte polymer having cationic functional groups to the surface of the bipolar plate to form a polyelectrolyte polymer layer on at least a portion of the surface; applying a hydrophilic second coating having anionic functional groups to the polyelectrolyte polymer layer so that an ionic bond is formed between the cationic functional groups in the polyelectrolyte polymer layer and the anionic functional groups in the hydrophilic second coating, wherein the second coating is derived from a material having the formula: wherein R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 , each may be H, Cl, or a saturated or unsaturated carbon chain having 1 to 4 carbon atoms, and wherein R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 , may be the same or different, and at least one of R 1 , R 2 , R 3 , R 4 , R 5 , or R 6 is a carbon chain with at least one carbon atom.
