Abstract
The present invention provides a method of production of a separator for a solid polymer type fuel cell characterized by shaping a substrate comprised of stainless steel, titanium, or a titanium alloy and then spraying the substrate surface with superhard core particles comprised of conductive compound particles of an average particle size of 0.01 to 20 μm mixed with a coating material and coated on their surfaces under conditions of a spray pressure of 0.4 MPa or less and a spray amount per cmof the substrate of 10 to 100 g in blast treatment. The ratio of the conductive compound to the mass of the core particles is 0.5 to 15 mass %.
