<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a membrane-electrode assembly in which short circuit between opposing electrodes through fluffy ends generated at cutting of gas diffusion layers is avoided, and a decrease in gas utilization efficiency at the power generation of a fuel cell can be suppressed. <P>SOLUTION: The method for manufacturing the membrane-electrode assembly includes cutting the membrane-electrode assembly 10 with a gas diffusion layer comprising, on both surfaces of an electrolyte membrane 11, catalyst layers 12a, 12b, and gas diffusion layers 13a, 13b thereon laminated in order so as to form a cut surface in the laminating directions T. The manufacturing method involves cutting the membrane-electrode assembly 10 while moving a cutting blade 30 perpendicularly to the laminating directions T. <P>COPYRIGHT: (C)2010,JPO&INPIT |
