Abstract:
1. A wave-shaped flow board suitable for a fuel cell, comprising: an injection-molded body substrate made from injection moldable polymer materials wherein the injection moldable polymer materials comprise polyetheretherketone, polyetherketoneketone, liquid crystal polymer and their compounds; at least a reaction zone recessed into a surface of the body substrate; and at least a wave-shaped current collector comprising a substrate made from stainless steel or other metal materials that are able to resist chemical corrosion from gaseous fuel of the fuel cell, which defines a plurality of independent fuel channels, the wave-shaped current collector being integrally mounted within the reaction zone and comprising a bendable conductive lug portion as an integral part of the wave-shaped current collector for providing an electrical connection between the wave-shaped current collector and a circuit on the surface of the wave-shaped flow board.
