Claim:
1. A method of depositing a conductive material to provide a uniformly conductive surface across an assembly of fuel cell components, the method comprising: providing a plate selected from anode plates, cathode plates, bipolar plates, or combinations thereof, wherein the plate comprises a side comprising gas flow channels; providing a diffusion media; mating a surface of the diffusion media with the gas flow channel side of the plate to form an assembly comprising an interfacial area between the diffusion media and plate, said interfacial area comprising electrically conductive contact points; and simultaneously depositing a conductive material to the mated diffusion media and plate by infiltrating the interfacial area with conductive material using a chemical vapor infiltration (CVI) process, thereby providing a uniformly conductive surface across the assembly.
