<P>PROBLEM TO BE SOLVED: To provide a separator capable of ensuring low contact resistance between welded separators and being produced in a short time. <P>SOLUTION: The separator is made by joining an anode separator 20A and a cathode separator 20B together by welding. While two sheets of work W1 and W2 to become the anode separator and the cathode separator are carried in layers in one direction with both sides held with a pair of rotatable electrode rollers 61A and 61B having projecting electrode parts 63A and 63B projecting from the surface in accordance with the shape of a portion 26 of the anode separator 20A and the cathode separator 20B to be welded together, the two sheets of work W1 and W2 held between the projecting electrode parts 63A and 63B are welded by applying an electric current to the projecting electrode parts 63A and 63B to form the separator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
