Abstract

See full text

The present invention concerns an alloy film for a metal separator for a fuel cell characterized by containing at least one noble metal element selected from Au and Pt and at least one non-noble metal element selected from the group consisting of Ti, Zr, Nb, Hf, and Ta, at a content ratio of noble metal element/non-noble metal element of 35/65 to 95/5, and having a film thickness of 2 nm or more. The present invention also relates to a manufacturing method of an alloy film for the metal separator for the fuel cell and a target material for sputtering, as well as the metal separator and the fuel sell. The alloy film for the metal separator for the fuel cell according to the invention is excellent in the corrosion resistance, has low contact resistance, can maintain the low contact resistance for a long time even in a corrosive environment, and is excellent further in the productivity.
