<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrolyte membrane for a fuel cell electrode, capable of transferring and positioning a reinforcement film material easily and cutting off a center portion of the reinforcement film material properly and stably without damaging an electrolyte membrane material in reinforcing the electrolyte membrane material. <P>SOLUTION: Reinforcement at the outer circumference of an electrolyte membrane material 11 is performed by removing a center portion 12b of a reinforcement film material 12 after the reinforcement film material 12 has been adhered to an entire surface of the electrolyte membrane material 11 so that transfer of the reinforcement film material 12 and positioning to the electrolyte membrane material 11 are easily performed. A center portion 12b of the reinforcement film material 12 is cut off by half cutting (two half-cuts respectively from the opposite sides) to the position from both the front surface and the rear surface of the reinforcement film material 12, and thereby, excessive or insufficient biting of a blade is eliminated in the half-cut. <P>COPYRIGHT: (C)2010,JPO&INPIT |
