Abstract:
1. An electrically conductive fluid distribution plate comprising: a metallic plate body defining a set of fluid flow channels configured to distribute flow of a fluid across at least one side of the plate wherein the metallic plate body includes lands adjacent the channels; a metal-containing adhesion promoting layer having a thickness less than 75 nm disposed on the plate body, the metal-containing adhesion promoting layer comprising a valve metal selected from the group consisting of titanium, zirconium, tantalum, niobium and mixtures thereof, the metal-containing adhesion promoting layer including a pure valve metal layer or a valve metal-containing alloy layer wherein the metal-containing adhesion promoting layer in the channels is substantially free of composite polymeric conductive material disposed theron; and a composite polymeric conductive layer disposed on the metal-containing adhesion promoting layer such that the metal-containing adhesion promoting layer adheres the composite polymeric conductive layer to the metallic plate body.
