Claim 12:
13. A method of operating an apparatus for fabricating a membrane-electrode-subgasket assembly comprising a feeding unit comprising a sheet feeding roller configured to feed a membrane-electrode assembly sheet having catalyst layers provided on both surfaces thereof; a cutting unit comprising a cutting roller and a support roller configured to rotate in engagement with the cutting roller, wherein the cutting roller is configured to partially punch portions outside each of the catalyst layers; a first pressing unit comprising a suction roller and a first hot roller; and a second pressing unit comprising second hot rollers, the method comprising:
feeding the membrane-electrode assembly sheet using the feeding unit;
forming a cut line in the fed membrane-electrode assembly sheet using the cutting unit, wherein forming the cut line comprises partially punching portions outside each of the catalyst layers;
separating a membrane-electrode assembly from the membrane-electrode assembly sheet having the cut line formed therein using the suction roller;
laminating the separated membrane-electrode assembly onto a first subgasket using the first pressing unit; and
laminating a second subgasket onto the membrane-electrode assembly using the second pressing unit.
