摘要： Disclosed is an apparatus for manufacturing a fuel cell. When blanking a continuous membrane electrode assembly (MEA) into individual MEAs and then bonding the individual MEAs to a sub-gasket, a scrap electrolyte membrane located at the continuous MEA is prevented from being bonded to a sub-gasket by release-purpose surface roughness formed on a surface thereof, so that it is possible to prevent manufacturing defects of the fuel cell. Further, when the individual MEAs are bonded to the sub-gasket, the continuous MEA is intended to be well bonded to the sub-gasket up to edge portions of the individual MEAs by the pressing force of a pattern roll.

摘要： Disclosed are a method of manufacturing a membrane electrode assembly for a fuel cell and a membrane electrode assembly for a fuel cell manufactured using the same. The planar membrane electrode assembly for a fuel cell may include an ionomer membrane formed on both side surfaces of an electrode and between the electrode and an electrolyte membrane, thereby increasing interfacial bonding force between the electrode and the electrolyte membrane and improving the durability of a cell. In addition, the membrane electrode assembly may include planar or smooth surfaces such that formation of voids or surface steps between the electrode and a sub-gasket may be prevented, thereby improving airtightness and preventing deterioration attributable to concentration of pressure.
