Abstract:
1. A method of manufacturing a fluid distribution plate comprising: providing a metallic plate body having a body defining a set of fluid flow channels configured to distribute flow of a fluid across at least one side of the fluid distribution plate wherein the metallic plate body includes lands adjacent the channels; forming a metal-containing adhesion promoting layer having a thickness less than 100 nm on the metallic plate body, the metal-containing adhesion promoting layer including a pure valve metal layer or a valve metal-containing alloy layer; and forming a composite polymeric conductive layer disposed on the metallic layer such that the adhesion promoting layer adheres the composite polymeric conductive layer to the metallic plate body wherein the metal-containing adhesion promoting layer in the channels is substantially free of composite polymeric conductive material disposed thereon.
