Abstract
In at least one embodiment, the present invention provides an electrically conductive fluid distribution plate and a method of making, and system for using, the 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 polymeric porous conductive layer proximate the plate body, with the porous conductive layer having a porosity sufficient to result in a water contact angle of the surface of less than 40°.
