Patent ID: 8820132

Claim:
A method for producing a separator for use in a polymer electrolyte fuel cell, comprising: adjusting and guiding a material to be formed, which is uncoiled by an uncoiler from a coil while controlled against meandering, in inclination angle by an approach angle adjuster into a separator-forming mill, introducing and pressurizing said material to be formed between a pair of rolls in said separator-forming mill, said rolls being vertically oppositely arranged to each other and each having circumferentially alternately a forming area with concaves and convexes created on a surface and a non-forming area with no concaves and convexes to continuously form a separator having passages created correspondingly to said concaves and said convexes, discharging and tension controlling the separator formed by said separator-forming mill by a pinch roll device with opposite widthwise ends of the separator being pinched, and cutting the separator discharged by the pinch roll device without stopping the same by a flying shear at portions with no passages formed.
