NOVELTY - A current collector for collecting an electric current generated in a fuel cell comprises substrate (11); collector pattern (12) formed on one side of the substrate, the collector pattern containing conductive material; and corrosion-resistant metal layer (14a) coated over all surfaces of the collector pattern including a surface facing the substrate.    USE - As current collector for collecting electric current generated in a fuel cell.    ADVANTAGE - The current collector prevents corrosion in the current collectors while the fuel cell is operated, thus increase the life span of the fuel cell, without forming the entire configuration with an expensive corrosion-resistant metal.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) manufacturing current collector for collecting electric current generated in fuel cell by forming collector pattern involving selectively applying corrosion-resistant metal over substrate; forming collector pattern by plating conductive material over the corrosion-resistant metal, and coating corrosion-resistant metal over surface of the collector pattern;    (2) fuel cell stack comprising a pair of flat end plates, a membrane electrode assembly (MEA) interposed between the pair of end plates, the membrane electrode assembly comprising electrolyte layer, and air electrode and fuel electrode coupled to either side of electrolyte layer, respectively; and current collector to collect electric current generated in membrane electrode assembly, the current collector comprising substrate, collector pattern formed on one side of substrate, the collector pattern containing conductive material; and corrosion-resistant metal layer coated over all surfaces of the collector pattern including surface of collector pattern facing the substrate; and    (3) fuel cell power generation system comprises fuel cell stack; fuel supply unit to supply fuel containing hydrogen to the fuel cell stack; and air supply unit to supply air to fuel cell stack, where the fuel cell stack comprises pair of flat end plates, a membrane electrode assembly (MEA) interposed between the pair of end plates, the membrane electrode assembly comprising an electrolyte layer, and an air electrode and fuel electrode coupled to either side of the electrolyte layer, respectively; and a current collector to collect an electric current generated in the membrane electrode assembly, the current collector comprising substrate, collector pattern formed on one side of substrate, the collector pattern containing conductive material; and corrosion-resistant metal layer coated over all surfaces of the collector pattern including a surface of the collector pattern facing the substrate.
