<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a fuel cell stack and a separator for a fuel cell capable of improving power generation efficiency of the fuel cell by reducing contact resistance by using minimum quantity of noble metal while applying surface treatment for obtaining corrosion resistant property. <P>SOLUTION: On the fuel cell stack, concave parts 95 and convex parts 98 constituting flow passages are formed on corresponding position of anode separators 93 and cathode separators 94, and bottom face of the concave parts of the anode separator 93 and the cathode separator 94 are jointed to each other. A noble metal layer 102 is formed at least on one of bottom faces 95a, 96a of the concave parts 95, out of the anode separators 93 and the cathode separators 94. <P>COPYRIGHT: (C)2007,JPO&INPIT |
