Patent ID: 8703361

Claim:
A membrane electrode assembly manufacturing method, comprising: an electrode forming step for forming a first electrode on a first release paper, and forming a second electrode corresponding to the first electrode on a second release paper corresponding to the first release paper; an incision part forming step for forming first incision parts with a predetermined length in the first release paper at a predetermined interval along the edge of the first electrode formed on the first release paper and second incision parts at a predetermined length in the second release paper with a predetermined interval along the edge of the second electrode formed on the second release paper; in response to forming the first incision parts and second incision parts, performing an adhesion step for adhering the first and second release papers formed with the first and second incision parts respectively on first and second side surfaces of an electrolyte membrane, wherein the first and second electrodes respectively face the electrolyte membrane, the first release paper excluding a first electrode area covering the first electrode is adhered to the first side of the electrolyte membrane, and the second release paper excluding a second electrode area covering the second electrode is adhered to the second side the electrolyte membrane; and a removing step for removing the first electrode area of the first release paper covering the first electrode along the first incision part and removing the second electrode area of the second release paper covering the second electrode along the second incision part wherein the first and second release papers excluding the first and second electrode areas remain adhered to the electrolyte membrane, wherein the portion of the first and second release paper that retains act as a sub-gasket.
