Title:
SEPARATOR FOR FUEL CELL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/129806
Kind Code:
A1
Abstract:
At first step S1, a passivation film (48) is removed by performing pickling on a separator (40) for fuel cell and then a new passivation film (42) is formed by performing heating at 200-280°C preferably. At second step S2, mechanical polishing is performed on the horizontal top surfaces (24a, 26a) in the waving portion (28) of the separator (40) for fuel cell, and a chipped portion (44) is provided by chipping off a part of the passivation film (42). At third step S3, the separator (40) for fuel cell is plated to form a first plating film (46) composed of gold, rhodium, platinum or an alloy of two or more kinds of them starting at the periphery of the chipped portion (44). A complex ion stabilizer for suppressing dissociation of complex ions is added to plating bath.
