Abstract
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.
Claims5
A method of manufacturing a fuel cell, the method comprising:
- blanking a continuous MEA withdrawn from an MEA winding roll into individual MEAs and forming release-purpose surface roughness on a surface of a scrap electrolyte membrane located at the continuous MEA;
- and
- bonding the individual MEAs to a sub-gasket withdrawn from a sub-gasket winding roll,
- wherein, when the individual MEAs are bonded to the sub-gasket, the scrap electrolyte membrane is configured to prevent the scrap electrolyte membrane from being attached to the sub-gasket by the release-purpose surface roughness.
