Abstract
In at least one embodiment, the present invention provides a hydrophilic electrically conductive fluid distribution plate and a method of making, and system for using, the hydrophilic electrically conductive fluid distribution plate. In at least one embodiment, the plate comprises a plate body defining a set of fluid flow channels configured to distribute flow of a fluid across at least one side of the plate, and a composite conductive coating having a water contact angle of less than 40° adhered to the plate body. In at least one embodiment, the composite coating comprises a polymeric conductive layer adhered to the plate body having an exterior surface, and a particulate carbon layer adhered to the exterior surface of the polymeric conductive layer.
