ABSTRACT:
A fluid flow plate is preferably formed with conductive member(s) and non-conductive material(s). The conductive member(s) and/or the non-conductive material(s) form portion(s) of land(s) and/or flow channel(s) on face(s) of the plate. The flow channel(s) pass between and/or among the land(s). The flow channel(s) can be optimized to service fluid(s) for a fuel cell assembly. The conductive member(s) form electrical path(s) between, among, about and/or around position(s) on the face(s) of the plate. The electrical path(s) serve to conduct electrical current generated by the fuel cell assembly. The non-conductive material(s) can form brace(s) for, and/or seal(s) with, portion(s) of the flow channel(s). The non-conductive material(s) can form portion(s) of a periphery of the face(s) of the plate, and/or portion(s) of any appropriate geometric feature(s) for the plate. The non-conductive material(s) can be injection-molded. The non-conductive material(s) can form means for aligning the fluid flow plate with an adjacent plate. The non-conductive material(s) can form means for maintaining clamping pressure on a component between the fluid flow plate and an adjacent plate.
