Method of coating a surface of a fuel cell plate
A method of coating a surface of a fuel cell plate is disclosed herein. The method involves forming a sol gel mixture including a metal oxide modified with at least one functional group, where the at least one functional group is configured to improve adhesion; and adding carbon modified with a hydrophilic functional group to the mixture, thereby forming a suspension. The suspension is applied to the surface of the fuel cell plate, and is activated to form a porous, hydrophilic, and conductive film on the surface of the fuel cell plate.
