Title:
COMPOSITE METAL FOIL FOR FUEL CELL SEPARATOR, FUEL CELL SEPARATOR, FUEL CELL, AND METHOD FOR PRODUCING COMPOSITE METAL FOIL FOR FUEL CELL SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2015/152379
Kind Code:
A1
Abstract:
The present invention provides a composite metal foil in which a surface of a titanium foil or titanium alloy foil is coated with a conductive layer, wherein a conductive film in which the percentage of the total occupied by TiO [ITiO/(ITi+ITiO)] at an X-ray diffraction peak of the surface of the titanium foil or titanium alloy foil, said percentage being determined from the TiO diffraction peak maximum strength (ITiO) and the titanium metal diffraction peak maximum strength (I­Ti), is at least 0.5%, and which has TiO dispersed inside an oxide film, is formed on the surface of the titanium foil or titanium alloy foil, and the conductive layer comprises 20-90 mass% of silver particles having an average particle size of 10-500 nm, inclusive, 0.2-1.0 mass% of a dispersing agent, and a balance consisting of an acrylic resin or an epoxy resin, and has a thickness of 5-50 µm.
