This disclosure provides a manufacturing method for manufacturing a fuel cell separator. The manufacturing method includes: providing a material sheet including a fiber sheet, carbon particles, and a resin, the carbon particles and the resin being applied to the fiber sheet; and pressing the material sheet into a recess-projection shape by which a gas circulation passage is to be formed, and forming a top portion and a shift portion. In the pressing of the material sheet, the material sheet is pressed such that a draft of the top portion is higher than a draft of the shift portion.

Fuel cell separator and manufacturing method for manufacturing fuel cell separator

The disclosure provides a fuel-cell separator excellent in conductivity and a method for producing the separator. A fuel-cell separator comprising a metal substrate and a surface layer formed on a surface of the substrate, wherein the surface layer comprises an antimony-containing tin oxide film in an outermost surface thereof, and the antimony-containing tin oxide film has a value (%) representing orientation of the (200) plane and calculated in accordance with Expression (1): where individual peak intensity values are obtained by X-ray diffraction, of 35 or more.

Fuel-cell separator

A method for forming an iron sprayed coating on a substrate with droplets of a wire molten by an electric arc includes: a step of forming a first iron sprayed coating on the substrate, the wire for arc spraying being a first wire containing iron and 0.03 to 0.10% by mass of carbon and the compressed gas being inert gas; and a step of forming a second iron sprayed coating on the first iron sprayed coating, the wire for arc spraying being a second wire containing iron and 0.03 to 0.10% by mass of carbon and the compressed gas containing 10 to 21% by volume of oxygen gas.

Method of forming a sprayed iron coating and coated member

A method of depositing a carbon particle-containing film that contains carbon particles includes: manufacturing film deposition slurry by mixing liquid into film deposition powder that contains carbon powder formed of the carbon particles; and depositing the carbon particle-containing film by spraying the film deposition slurry to a surface of a base material so that the liquid is vaporized.
