A current collector, a method of manufacturing the current collector, a fuel cell stack, and a fuel cell power generation system are disclosed. The current collector for collecting an electric current generated in a fuel cell can include: a substrate; a collector pattern, which contains a conductive material, formed on one side of the substrate; and a corrosion-resistant metal layer, which is coated over all of the surfaces of the collector pattern, including the surface facing the substrate. This current collector can be utilized to prevent corrosion during the operation of the fuel cell, as well as to increase the life span of the fuel cell, without forming the entire configuration with an expensive corrosion-resistant metal.
