A wave-shaped flow board suitable for a fuel cell includes an injection-molded body substrate, a reaction zone recessed into a surface of the body substrate, and a wave-shaped current collector, which defines a plurality of independent fuel channels. The wave-shaped current collector is integrally mounted in the reaction zone and comprises a bendable conductive lug portion for providing an electrical connection between the wave-shaped current collector and a circuit on the surface of the wave-shaped flow board.
